Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 to 11 and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Embodiments of the invention are described in further detail below with reference to the drawings.

Referring to fig. 1, an embodiment of the present invention provides an equidistant hole distribution step blasting method, and a main flow of the equidistant hole distribution step blasting method is described as follows:

step 100: and acquiring blasting area information.

The blasting area information is information of an area position where blasting is required. The acquisition mode is a manual input mode, namely a preset manual region. That is, the area is drawn in a CAD drawing, and in this embodiment, the blasting area information in the general planning process that needs to be known is generally a relatively regular pattern, and is generally rectangular.

Step 101: dividing the area corresponding to the blasting area information into a plurality of regular area information and irregular area information, wherein the areas corresponding to the regular area information are parallelograms, and the areas corresponding to the irregular area information are other areas except the regular area information in the blasting area information.

The pattern of the regular area information is an image of a parallelogram. The pattern corresponding to the irregular area information is other areas except the regular area information in the blasting area information. As shown in fig. 2, in order to realize the concept of the optimal free surface and solve the problems of the wide hole pitch small resistance line blasting technique in popularization and practicality, a quasi-equal resistance free surface step drilling blasting technique is adopted, and the quasi-equal resistance free surface step drilling blasting technique refers to equal hole pitch hole arrangement, so that the distances from each blast hole to adjacent blast holes are equal. The pattern corresponding to the regular region information is a parallelogram, and the minimum internal angle of the parallelogram is 60 degrees. When the blasting area is not a parallelogram, the blasting area can be divided into a plurality of parallelograms and other shapes, and the images of the other shapes are the areas corresponding to the irregular area information. When the blasting area information is known, the blasting area information is drawn in a CAD drawing according to an equal proportion, then patterns corresponding to the regular area information are sequentially placed in the CAD drawing, and the rest areas are the irregular area information.

Step 102: and determining equilateral triangle information according to the preset blast hole diameter information and the regular region information.

The blast hole diameter information is information of the diameter of the blast hole filled with explosive. The equilateral triangle information is information of a shape formed by connecting three adjacent blast holes in series. As shown in fig. 2 and 3, the rock drilling and blasting technique of equi-hole distance hole arrangement refers to arranging holes according to an equilateral triangle row by row along the direction of the free surface of a working line, so that the distance between each blast hole and an adjacent blast hole is the same. The determination mode is set by a worker according to the actual blasting environment, the side length of the regular triangle is 25-40 times of the diameter of the blast hole, and the diameter of the blast hole is selected according to the actual situation.

Step 103: and analyzing coordinate points and equilateral triangle information of the region corresponding to the rule region information to obtain the point position information of the reference blast hole.

The reference blast hole point location information is information of the location of the blast hole from which the first blasting starts. As shown in fig. 2, after the regular region information is divided, each regular region information has four boundary lines and boundary inflection points, then the boundary inflection point of the maximum interior angle position is obtained, and then the point position which is in the same equilateral triangle and is not on the boundary line is the reference blast hole point position information.

Wherein, the big gun hole is vertical setting, and perpendicular big gun hole promptly, perpendicular big gun hole can avoid the slope drilling to cause drilling direction and detonation direction inconsistent and influence blasting effect.

Step 104: and determining the residual blast hole point position information according to the reference blast hole point position information and the equilateral triangle information.

The remaining blast point position information is remaining other blast point position information than the reference blast point position information, and as shown in fig. 2, all blast points and adjacent blast points of the reference blast point position information and the remaining blast point position information form an equilateral triangle every three.

Step 105: and determining detonating isochrone information according to the reference blast hole point position information and the residual blast hole point position information.

The detonating isochronous line information is the information of the straight line formed by connecting the blastholes detonated simultaneously. As shown in fig. 2, the straight line 3 in the figure is determined by CAD drawing.

Step 106: and determining detonation sequence information according to the reference blast hole point position information and the detonation isochrone information.

The detonation sequence information is that the detonation is carried out row by row according to the sequence of 1, 2 and 3 in the figure from the reference blast hole point position information with two free surfaces, if the detonation by row is adopted, the ignition time of each blast hole is specially noted, and the whole detonation sequence is ensured to be unchanged. The hole-by-hole detonation technology ensures that the isochrone and the detonation sequence are basically consistent, and the jump phenomenon cannot occur.

Step 107: and after explosive is filled in blastholes corresponding to the basic blasthole point position information and the residual blasthole point position information, sequentially detonating the blastholes row by row according to the detonation sequence information from the basic blasthole point position information.

The explosion delay time of the adjacent isochrones is 4-6 ms of the interval between the adjacent isochrones, the blastholes corresponding to the explosion isochrones 3 are simultaneously detonated, so that each blasthole is detonated to act independently and instantaneously, the detonated explosion body collides with the explosion body of the blasthole detonated before, the kinetic energy obtained by the explosion body is converted into the energy of broken rock, and the utilization rate of the explosive energy in open-air step drilling explosion is improved.

With reference to fig. 3 and 4, the free face AB of the blasthole O becomes two free faces AB, AC, and the blasthole density coefficient m (hole pitch/row pitch) becomes superficially large, and with reference to fig. 2, m=2tan 30 °, which is approximately equal to 1.15, when the inter-row sequence is initiated front. Referring to fig. 3, when the side detonation (including inter-row sequence or inter-row hole-by-hole sequence) is performed, m=2tan 60°, which is approximately equal to 3.46, the blasting with wide hole pitch and small resistance line is effectively realized, and the utilization rate of explosive energy in the blasting is improved.

Referring to fig. 4, from the ideal free surface concept, an optimal m coefficient diagram is derived, in fig. 4, ABCO is the gun hole position, AB length is the hole pitch, OP is the row pitch, and the ratio of AB to OP is m. Let the ratio of fan OEF to diamond ABCO area be a function f (m) of the blast hole density coefficient m, namely:

The change in f (m) at m=2.6 to 8 is shown in table 1.

As can be seen from table 1, the maximum value of f (m) is obtained when m=3.2, that is, the degree of fit between the sector and the diamond is the best, and at this time, the explosive energy is fully utilized, and the specific charge of the same rock breaking degree is the smallest.

Whereas drilling is performed with equal pitch arrangement, the diagonal sequence detonates, m=3.46, f (m) =90.69%, f (m) is reduced by 0.32% compared with the optimal value m=3.2, but the arrangement is more convenient. And when m=4 to 8, f (m) gradually decreases as m increases.

Referring to fig. 5, the method of acquiring blast area information includes:

step 200: and acquiring actual blasting surface information.

The actual blasted surface information is information of the surface of the blasted area, that is, information of one plane in general, but when the blasted area is on a mountain, the surface is easily rugged, so that blasthole depths of the entire area are easily inconsistent. The acquisition mode can be that the detection robot detects, namely the robot is provided with a locator and an altitude tester, and then cruises in the blasting area and outputs coordinate points and altitude in real time.

Step 201: and analyzing and determining the lowest point position information and the horizontal area information according to the actual blasting surface information.

The lowest point location information is obtained by carrying out equivalence on the whole actual blasting surface information in a planar mode, then simulating coordinate points corresponding to the basic blast hole point location information and the residual blast hole point location information, searching corresponding altitude one by one, and then screening out the lowest altitude, wherein the blast hole point location corresponding to the lowest altitude is the lowest point location information. The horizontal area information is formed after any blast hole point which becomes an equilateral triangle in the whole actual blasting surface information is located in the same altitude information.

Step 202: and determining the actual blast hole height information according to the minimum point position information and the preset required blast hole depth information.

The actual blast hole height information is information of a height which ensures the explosion efficiency by punching a blast hole with a coordinate point corresponding to the lowest point position information and at least the blast hole with the depth consistent with the depth of the required blast hole depth information. The required blasthole depth information is information of the depth of blastholes to be drilled in order to achieve the blasting effect and in the case that the blasting influence distance is one pitch. The determination mode is to subtract the depth value of the required blast hole depth information from the altitude corresponding to the lowest point position information.

Step 203: and determining blasting area information according to the actual blast hole height information and the horizontal area information.

Since a point and a plane parallel to the blast zone information are known, information of the plane passing through this point can be obtained. The determined manner may be that of Solidworks. In this embodiment, after knowing the altitude of the lowest point, the drilling depth of each other point can be set according to the altitude of the lowest point, where the drilling depth is generally the sum of the altitude difference of the lowest point and the corresponding blasthole and the required blasthole depth information, and then all the blasthole points are connected to form blasting area information; the height of each hole site may also be verified in accordance with the horizontal area information.

Referring to fig. 6, a further determination method of blasting area information includes:

step 300: and acquiring the point position information of the current blast hole.

The current blast hole point position information is information of the point positions of randomly selected blast holes, and comprises reference blast hole point position information and residual blast hole point position information. The acquisition mode is a direct screening mode.

Step 301: and calculating actual blast hole depth information corresponding to the current blast hole point position information according to the actual blast hole height information.

The actual blasthole depth information is information of the punching depth corresponding to the actual blasthole height information needed to be achieved at the current blasthole point position information.

Step 302: and judging whether all the actual blast hole depth information is smaller than preset influence depth information.

The depth-affecting information is information of the deepest depth of the deep hole blasting, that is, the depth or less does not generally affect the effect of the blasting. That is, the purpose of the judgment is to determine the case where the blast cannot be performed once because the actual blast hole depth is too deep.

Step 3021: if the actual blast hole depth information which is smaller than the influence depth information exists, screening out the current blast hole point position information with the maximum actual blast hole depth information, and defining the blast hole point position information as the highest blast hole point position information.

The highest blasthole point location information is current blasthole point location information with the largest blasthole depth when drilling is carried out according to the actual blasthole depth information. And comparing the actual blast hole depth information of each blast hole point one by one, and selecting the actual blast hole depth information. The purpose of screening is to blast from top to bottom, so it is necessary to determine the first descent height thereof. If so, it is indicated that the blasting cannot be completed by one time, and two or more blasting operations are required.

Step 3022: and if the blast area information is smaller than the horizontal area information, determining the blast area information according to the actual blast hole height information and the horizontal area information.

If the blast area information is smaller than the actual blast hole height information, the blast area information can be determined directly according to the actual blast hole height information and the horizontal area information. The determination method is consistent with step 203.

Step 303: and determining primary blasting area information according to the highest blast hole point position information, the horizontal area information and the influence depth information.

The primary blasting area information is information of a blasting area in which blasting is performed for the first time. Namely, knowing the altitude of the highest blast hole point location information and then knowing the influence depth information thereof, the altitude of the blasting horizontal plane in the largest influence range can be calculated. The determination method is to subtract the depth affecting the depth information from the altitude of the highest blast hole point location information, then obtain a coordinate point located in the primary blasting area information, and then determine the plane of the primary blasting area information according to the horizontal area information parallel to the primary blasting area information, where the determination method is consistent with step 203, and details are not described herein.

Step 304: and determining primary reference blasthole point position information and primary residual blasthole point position information in the area corresponding to the primary blasting area information, updating the current blasthole point position information after performing row-by-row blasting, and continuously judging whether all the actual blasthole depth information is larger than the influence depth information.

The primary reference blast hole point location information is the reference blast hole point location information determined by the method of steps 100-106 after the primary blasting area information is taken as the actual blasting area. The primary residual blast hole point location information is residual blast hole point location information determined by the method of steps 100-106 after the primary blasting area information is taken as an actual blasting area. At this time, the punching depth of the point positions corresponding to all the primary reference blast hole point position information and the primary residual blast hole point position information is smaller than or equal to the influence depth information. Then, since all the blast hole points have disappeared after blasting, the steps 100-106 are re-simulated to make the simulated blast hole points appear, but since the altitude of the blast hole point at this time is reduced due to the primary blasting, the current blast hole point information needs to be updated again, and then whether all the actual blast hole depth information is larger than the influence depth information is continuously judged.

Referring to fig. 7, the method for loading explosives in blastholes corresponding to the reference blasthole point location information and the remaining blasthole point location information includes:

step 400: and acquiring the stemming soil property information corresponding to the current stemming point position information.

The blasthole soil quality information is information of the quality of soil near the blasthole position corresponding to the current blasthole point position information. Can be obtained by sampling and detecting in advance by staff.

Step 401: and calculating the hole pitch information of the blast holes according to the equilateral triangle information.

The hole pitch information is the information of the distance between two adjacent holes. As shown in fig. 3, it can be clearly known that the hole pitch information is triangle side length information corresponding to the equilateral triangle information.

Step 402: and calculating the current blasthole depth information according to the current blasthole point position information and the actual blasthole depth information.

The manner of calculation is identical to step 301.

Step 403: and carrying out matching analysis according to the blasting explosive quantity information and the blasthole pitch information stored in the preset explosive quantity database, the current blasthole depth information and the blasthole soil property information to determine the blasting explosive quantity corresponding to the blasthole pitch information, the current blasthole depth information and the blasthole soil property information, and defining the blasting explosive quantity as current blasting explosive quantity information.

The current blasting explosive quantity information is information of the explosive quantity which can influence the soil quality in the range of the hole pitch of the blast hole under the conditions of the current depth of the blast hole and the soil quality of the blast hole. The database stores mapping relations of blasting charge information, blasthole pitch information, current blasthole depth information and blasthole soil property information, and results are obtained by workers in the field according to actual work and test experiments. When the system receives the hole pitch information, the current hole depth information and the hole soil information, the corresponding current blasting charge information is automatically searched from the database and output.

Step 404: and carrying out matching analysis according to the distribution proportion information stored in the preset distribution database and the current blasthole depth information to determine the distribution proportion corresponding to the current blasthole depth information, and defining the distribution proportion as current distribution proportion information.

The current distribution proportion information is information of the explosive quantity distribution of which the explosion influence of each depth is identical at different depths in the same blast hole. The distribution database stores the mapping relation between the distribution proportion information and the current blast hole depth information. The distribution ratio is recorded by the workers in the field after distributing different depths according to actual conditions until the explosion influence is the same.

Step 405: and filling the current blast hole point position information according to the current blasting explosive quantity information and the current distribution proportion information.

When the current blasting explosive quantity information and the current distribution proportion information are known, filling can be carried out according to the corresponding explosive quantity and proportion.

Referring to fig. 8, the method of determining rule area information includes:

step 500: and acquiring mining band width information.

The mining strip width information is information of the width of an actual rock mass which is mined by one excavator at a time. Is determined by the excavating radius and unloading radius of the excavator and the blasting parameters. The acquisition mode can be obtained through direct calculation or direct test and excavation.

Step 501: and analyzing the blasting width information and the blasting length information according to the blasting area information.

The blast width information is information of a width value of the blast area. The burst length information is information of the length of the burst area. The analysis mode is obtained by direct measurement from CAD drawings.

Step 502: judging whether the mining band width information is smaller than a width value corresponding to the blasting width information.

The purpose of the judgment is to determine whether or not a rule area information of the mining strip width can be set.

Step 5021: if the length information is smaller than the blasting width information, calculating theoretical length information according to the preset length-width ratio information and the mining bandwidth information.

The aspect ratio information is information of the length and width of the parallelogram set for human. Typically greater than 3, in order to reduce clip fabrication and damage to subsequent drilling platforms. The theoretical length information is information of a theoretical length obtained by calculating the length according to the width of the mining belt as the width of the rule area information and then the length according to the aspect ratio information. If the information is smaller than the preset value, the information can be set with the width of the mining band width information in the width direction, and whether the theoretical length information can be put in or not is only needed to be judged. The purpose of the blasting area set to be one mining area width is to facilitate the user to excavate it once without leaving residues after blasting.

Step 5022: if the length is larger than the explosion width information, calculating actual length information according to the length-width ratio information and the explosion width information.

The actual length information is information of a length corresponding to the actual width obtained by taking the blasting width information as the width of the regular area and then calculating the length according to the aspect ratio information. If the width is larger than the width, the width of the mining area cannot be reached, the blasting can only be carried out according to the actual blasting width, and whether the actual length information obtained according to the blasting width information and the aspect ratio information can be placed in the blasting area or not can be calculated.

Step 503: and judging whether the theoretical length information is smaller than the blasting length information.

The purpose of the judgment is to determine whether the calculation can be performed in accordance with the theoretical length information.

Step 5031: if the length information is smaller than the blasting length information, the width of the mining band is taken as the width of the rule area information, and the length of the theoretical length information is taken as the length of the rule area information to divide the corresponding rule area information.

If the information is smaller than the preset value, the description can be set according to the theoretical length information, and the area is divided according to the most suitable mining band width information as the width and the theoretical length information as the rule area information of the length.

Step 5032: if the length information is larger than the blasting length information, the mining band width information is used as the width of the rule area information, and the blasting length information is used as the length of the rule area information to divide the corresponding rule area information.

If the length is larger than the predetermined length, it is determined that the length cannot be set as the length of the regular area information according to the theoretical length information, and the regular area information is set according to the blasting length information so as to be as close to the aspect ratio as possible.

Step 504: and judging whether the actual length information is smaller than the blasting length information.

The difference between the step 503 is that the actual length information and the name of the theoretical length information and the actual length value are the same, and the purpose of the judgment is the same.

Step 5041: if the length information is smaller than the blasting length information, the blasting width information is used as the width of the regular area information, and the actual length information is used as the length of the regular area information to divide the corresponding regular area information.

If smaller than, the description may be set according to an appropriate aspect ratio, and the division of the area is performed according to the relatively appropriate blasting width information as the width and the actual length information as the regular area information of the length.

Step 5042: if the length information is larger than the explosion length information, the explosion width information is used as the width of the rule area information, and the explosion length information is used as the length of the rule area information to divide the corresponding rule area information.

Step 5032 is performed with the difference that the specific values of the two are different.

Referring to fig. 9, the method for dividing the area corresponding to the blast area information into a plurality of regular area information and irregular area information after dividing the corresponding regular area information by using the mining bandwidth information as the width of the regular area information and the theoretical length information as the length of the regular area information includes:

step 600: and acquiring elongation information according to the regular region information.

The elongation information is the value of the length of the longer side in the parallelogram, i.e. the value of the hypotenuse in the vertical direction, and is the distance value of the AC side in the horizontal direction as shown in FIG. 4. The acquisition mode is to measure on a CAD drawing.

Step 601: and calculating the actual demand length information from the blasting length information and the extension length information.

The actual required length information is a value that the length of the actual required changes due to the fact that the distance value in the length direction occupied by the parallelograms after being overlapped with each other is increased by one more extension length information. The manner of calculation is the burst length information minus the extension length information.

Step 602: dividing the actual demand length information and the theoretical length information, and rounding, wherein rounded data are defined as length multiple information.

The length multiple information is information of the maximum number which can be placed by arranging the rule area information in length according to the length information of the actual requirement. The calculation mode is that the actual demand length information is divided by the theoretical length information, and then the integer part is taken. Since the length of the superimposed regular region information is an integer multiple of the theoretical length information, the result obtained by calculation can only take an integer part and cannot be larger than the value.

Step 603: dividing the blasting width information and the mining bandwidth information and rounding, wherein rounded data are defined as width multiple information.

The width multiple information is information of the maximum number which can be placed by arranging the rule area information in width according to the length information of the actual requirement. The manner and purpose of the calculation is the same as in step 602.

Step 604: and acquiring the initial length boundary information and the initial width boundary information of the blasting area information.

The purpose of the acquisition is to determine the starting position of the arrangement rule area information.

Step 605: and determining initial rule area information according to the initial length boundary information and the initial width boundary information.

The initial rule area information is first divided rule area information. The determination mode is that the long side of the regular area information is attached to the boundary line corresponding to the initial length boundary information, then the hypotenuse of the regular area information is close to the initial width boundary information until the long side and the initial length boundary information are intersected, and the position of the initial regular area information is obtained.

Step 606: and sequentially determining the information of the remaining rule area according to the length multiple information and the width multiple information.

Remaining rule area information remaining determined rule area information after the initial rule area information is divided. The determining mode is that the oblique sides of the initial regular area information and the initial width boundary information are attached to one side of the initial regular area information, and the long sides of the initial regular area information and the initial length boundary information are attached to one side of the initial regular area information and the initial width boundary information and then are sequentially overlapped and determined until the next regular area information cannot be put down in the remaining area according to the arrangement mode of the initial regular area information.

Step 607: and determining irregular area information in the blasting area information according to the initial regular area information and the residual regular area information.

When all the initial regular area information and the residual regular area information are determined, the residual areas in the blasting area information are irregular area information.

Referring to fig. 10, the determination of blast hole point location information within irregular area information includes:

step 700: and acquiring adjacent regular area information of the irregular area information and corresponding adjacent boundary line information.

The adjacent regular region information is information of a regular region adjacent to the irregular region. The adjacent boundary line information is information of a boundary line on one side close to the irregular area information. Since the irregular area information cannot be put down in the irregular area information, the irregular area information is smaller than the regular area information in at least width or length and is necessarily adjacent to the regular area information.

Step 701: and determining simulation rule area information according to the adjacent rule area information and the adjacent boundary line information.

The simulated rule area information is the information of the simulated rule area with the same length and width as those of the adjacent rule area information and the same placement mode. The simulated regular region information is attached to adjacent boundary line information of adjacent regular region information, so that the position and shape of the simulated regular region information can be obtained.

Step 702: and analyzing coordinate points and equilateral triangle information of the area corresponding to the simulation rule area information to obtain simulation reference blast hole point location information.

The simulated reference blast hole point location information is the reference blast hole point location information in the simulated regular region information. When the simulation rule area information is determined, the reference blast hole point location information thereof may be determined according to step 103.

Step 703: and determining simulated residual blast hole point position information according to the simulated reference blast hole point position information and the equilateral triangle information.

The steps of step 104 are the same as those of step 104, and will not be described in detail herein.

Step 704: and determining the simulated detonation isochrone information according to the simulated reference blast hole point position information and the simulated residual blast hole point position information.

The steps in this step are the same as step 105, and will not be described in detail here.

Step 705: and determining the simulated detonation sequence information according to the simulated reference blast hole point position information and the simulated detonation isochronal line information.

The steps of step 106 are the same as those of step 106, and will not be described in detail herein.

Step 706: according to the irregular area information, determining simulated reference blasthole point position information, simulated residual blasthole point position information, simulated detonating isochrone information and simulated detonating sequence information which fall into the irregular area information, and respectively defining the simulated reference blasthole point position information, the simulated residual blasthole point position information, the simulated detonating isochrone information and the simulated detonating sequence information which fall into the irregular area information into actual reference blasthole point position information, actual residual blasthole point position information, actual detonating isochrone information and actual detonating sequence information.

The actual reference blasthole point location information, the actual residual blasthole point location information, the actual detonating isochrone information and the actual detonating sequence information are simulated reference blasthole point location information, simulated residual blasthole point location information, simulated detonating isochrone information and simulated detonating sequence information which fall into the irregular area information respectively. The determination mode is that coordinate analysis is directly carried out on the CAD graph, and if the coordinates are in a coordinate range corresponding to the irregular area information, the actual reference blast hole point position information, the actual residual blast hole point position information, the actual detonating isochrone information and the actual detonating sequence information can be determined.

Step 707: and detonating the blastholes corresponding to the actual reference blasthole point position information and the actual residual blasthole point position information row by row according to the actual detonating sequence information.
