After the blasting area is obtained, the conditions of the peripheral free surfaces and the constraint conditions thereof in the blasting area need to be judged. It is worth mentioning that the blasting area of the open bench in the method comprises at least one free surface.
Specifically, the implementation process of step S101 is shown in fig. 2, and includes:
step S21, determining the blasting area of the open bench and the corresponding blasting range thereof according to the collected geological data of the open bench;

and step S23, determining the position data and the charging data of the blast hole according to the blasting parameters.
After the blasting range of the blasting area is determined, the position data and the charging data of the blast hole can be obtained; generally, the blast holes are uniformly distributed in the blasting area and are arranged in the blasting area in an arrangement mode. The charging data of the blast holes are determined according to the geological conditions of the actual positions of the blast holes, and the data can be automatically generated by using corresponding tools.
In a specific scene, an actual blasting area is planned according to geological data of an open bench blasting area, and then corresponding parameters such as ore rock performance parameters, explosibility grading, drilling diameter and explosive performance, free surface conditions around the blasting area, blasting effect requirements and the like are input into a related computing system, so that position data and charging data of blast holes are directly obtained.
And S102, determining the blasting holes in the blast holes by using the free surface data of the blasting area and the expected blasting effect, and sequentially determining the blasting order of other blast holes according to the blasting holes.
The blasting hole is used as the starting point of blasting and is the most key blast hole in the blasting network; the blasthole is determined by combining the free surface condition of the blasting area and the final expected effect of blasting; since the blasting area may simultaneously include the mixed situation of the ore and the rock or the blasting areas of different grades of ore, the number of the blasting holes can be set according to the situation of the ore area and the rock area, and the number of the blasting holes can be multiple.
In some embodiments, the step S102 is shown in fig. 3, and includes:
step S31, determining a row of blast holes on the back boundary line of the blasting area as back rows of blast holes according to the position data of the blast holes;
step S32, acquiring free surface data of a blasting area, selecting blast holes capable of achieving the expected blasting effect from the first row of blast holes under the constraint of the free surface data, and determining the blast holes as blasting holes;
and step S33, sequentially determining the blasting order of other blast holes except the initial blast hole according to the corresponding blasting expected effect.
In the process of determining the plurality of the detonating holes, the blast holes are respectively designed for the corresponding physical and mechanical property parameters in the ore area and the rock area, and meanwhile, the positions of the respective detonating holes are determined. Wherein the rock mass data involved at least comprise: the integrity coefficient of the rock, the density of the rock, the firmness coefficient of the rock, and the step height; the corresponding blast hole parameters include at least: the type of the drilling machine, the diameter of a drill bit, the diameter of a drilled hole, blast hole charging data, a hole distribution mode, the type of explosive and the like. And determining the blasting sequence of each blast hole by calculating the data by taking the final blasting effect as a target. Generally, the principle of selection of the initiation hole is to make the best use of the free surface as possible.
When ore rocks are selected in the blasting area to mine blasting or ores of different grades, setting blasting points on the ore area and the rock area or ore areas of different grades respectively on the basis of ore rock boundary lines to complete a blasting network; when the explosion area has a side free surface, the explosion point position can be arranged at a convex part at the junction of the two free surfaces. The position of the optimal initiation point and the initiation time of the two initiation points are determined through calculation, so that blast holes at the boundary of ore rocks or at the boundaries of ores of different grades are initiated at the same moment, and the blasting directions are opposite.
And S103, sequentially determining blasting delay time of the blast holes and the detonating holes according to the corresponding blasting sequence of the blast holes according to the geological conditions of the blast holes, and determining the blasting delay time as the detonating time data of the blast holes.
And determining the blasting delay time of the blast hole and the blasting initiation hole on the premise of meeting the blasting requirement according to the geological condition of the blast hole and the blasting parameters. In general, after the initiation hole is detonated, the adjacent blast holes are blasted one by one, so that for other blast holes, the blasting delay time of the rest blast holes is determined.
Specifically, the process of obtaining the blasting delay time is shown in fig. 4, and includes:
and step S41, determining the inter-hole delay time and inter-row delay time of other blast holes and the initiation hole by using the geological condition parameters of the blast hole.
In an actual scene, a row of blast holes on the back boundary line of the blasting area can be determined as back rows of blast holes according to the position data of the blast holes; and determining a row of blast holes on the crest line of the blasting area as a first row of blast holes. Generally, the time delay between holes of the first row of blast holes is 5-17 ms; the inter-row delay time is 25-50 ms; the inter-row delay time of the blast holes in the back row is 65-100 ms.
And step S42, according to the blasting sequence of the blast holes, sequentially determining the blasting delay time of the blast holes by using the inter-hole delay time and the inter-row delay time of other blast holes and the initiation hole.
If there is ore rock or a mixed area of different grades in the blasting area, it is necessary to set the blasting points on both sides based on the dividing line, so as to complete the design process of the blasting circuit, where step S103 includes, as shown in fig. 5:
step S51, determining a boundary of the mixed region according to the position data of the mixed region; wherein the dividing line includes at least: the boundary between the ore region and the rock region and the boundary between the ore regions of different grades;
step S52, respectively determining corresponding detonating holes in the mixed area by using boundary lines; the blasting holes corresponding to the areas on the two sides of the boundary are arranged in the same row of blast holes, and the blasting holes on the two sides of the boundary correspond to the blast holes between the boundaries one by one;
and step S53, dividing other blast holes in the areas on both sides of the boundary line in sequence, and determining the blasting sequence according to the corresponding blasting expected effect.
Drawing a boundary of ore rocks or ores of different grades in the same explosion area, and respectively arranging explosion points at two sides of the boundary. Whether the side surface of the explosion area has a free surface or not, the position of the optimal initiation point and the initiation moments of two initiation points are determined; finally, adjacent blast holes at the boundary of each ore discharge rock or at the boundary of ores of different grades are detonated at the same time.
If there are additional blast holes in the regions on both sides of the boundary in the direction away from the boundary, the blast orders of the additional blast holes are determined in order in the direction away from the boundary.
And step S104, generating the blasting network of the open bench by using the position data of the blast holes, the time data of the blast holes and the charging data of the blast holes.
The following describes the design method of the open bench blasting network in combination with a specific scene, the blasting area of the open bench can be planned according to geological data of the blasting area of the open bench from the figure 6, and corresponding ore performance parameters, explosive classification, drilling diameter and explosive performance, free surface conditions around the blasting area and blasting effect requirements are input through related tools, so that automatic design of blast holes is completed, and position data and charging data of the blast holes are determined. Meanwhile, according to the positions of the blast hole and the free surface, the position of the detonating hole is arranged at the lower left corner in the figure 6.
In the blasting hole detonation process in fig. 6, a high-precision detonator or an electronic detonator is adopted for detonation, and the optimal delay time of a detonation zone is determined according to the position of a blasting hole and the corresponding geological condition, wherein the delay time between front row holes is 5-17ms, the delay time between rows is 25-50ms, and the delay time between the last row holes is 65-100 ms. After the corresponding delay time of each blast hole is obtained, the layout of the open bench blasting network can be obtained. As can be seen from fig. 6, each blast hole corresponds to the blasting delay time, and the blasting sequence is from the lower left corner, extends to the right side in a consistent manner, and finally completes the blasting in turn.
The sorting mining blasting of the boundary area of the ore or the ore areas of different grades is carried out by firstly drawing an ore boundary line in the blasting area, arranging blasting areas of ore and rock or ore of different grades in the blasting area, respectively arranging blasting points, and carrying out sectional blasting on blasting circuits of ore and rock or ore areas of different grades at the same time, as shown in figure 7.
FIG. 7 includes two blastholes, one in each of the first rows of blastholes in FIG. 7; the blasting direction of the left blasting hole is rightward and upward; correspondingly, the blasting directions of the right-side blasting holes are leftward and upward. And blasting the blast holes on the two sides in opposite directions respectively at the preset boundary positions to form a deep groove. As can be seen from fig. 7, the delay times of the blastholes on the two sides of the deep trench are in a one-to-one correspondence relationship.
Specifically, in fig. 7, a boundary of ore rocks or ores of different grades is arranged in the same blasting area, and blasting points are respectively arranged on two sides of the boundary. Whether the side surface of the explosion area has a free surface or not, the position of the optimal initiation point and the initiation moments of the two initiation points can be determined; finally, adjacent blast holes at the boundaries of each ore discharge rock or at the boundaries of ores of different grades are detonated at the same time, and the time delay between the blast holes at the two sides of the boundaries is 75-100 ms.
It should be noted that the right-side detonating hole has corresponding blast holes to be blasted on the right side, and the time intervals of the blast holes can be obtained by referring to a single detonating hole mode, which is not described herein again.
In the respective detonating circuits in the ore area and the rock area or the ore areas with different grades are detonated, high-precision detonators or electronic detonators are needed to ensure that blast holes corresponding to the boundary line between the ore area and the rock area or the ore areas with different grades can be detonated simultaneously, and finally a deep groove is formed at the boundary line between the ore and the rock or the ore areas with different grades. The deep groove is beneficial to sorting and mining, so that the dilution rate of the ore is reduced.
According to the design method of the open bench blasting network, after the blast holes are distributed, the method can automatically determine the detonation position according to the free surface condition around the blasting area and the requirement of the blasting effect, and determine the optimal detonation time of each blast hole in the blasting area. For the mixed situation of ore, rock and ore explosion areas of different grades in the blasting area, the ore rock can be divided out according to a plan view or the grade boundary lines are respectively provided with respective blasting points; and finishing the design of the detonating network and the delay time of the blast holes on two sides of the boundary of the ore rock according to the arrangement design of the blast holes in each area. Therefore, the method can be applied to the step blasting design of complex ore bodies, particularly under the condition of ore rock grading mining blasting or grading mining blasting of different grades of ores, a deep groove can be formed at the junction of the ore rocks after blasting, grading mining is convenient to realize, the loss and dilution rate of the ores is reduced, and the problems of low automation degree and poor blasting effect in the prior art are solved.
