At present, the explosive quantity needed to be used when blasting the ore rock on the goaf is usually set according to manual experience, so that the blasting explosive quantity is unreasonable in setting and cannot play a good blasting effect, and the filling effect of the blasted ore rock on the goaf is general.
Based on this, in order to improve the effect of filling the goaf, the embodiment of the present application provides a method for determining a blasting explosive amount, which may be applied to a terminal device such as a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), and the like, and the embodiment of the present application does not set any limit to a specific type of the terminal device.
Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a method for blasting a to-be-blasted area according to an embodiment of the present application, where the method includes the following steps:
s101, determining target geological parameters and a surface range of a to-be-blasted area above the goaf.
In one embodiment, the surface area may be characterized by the surface area of the area to be blasted. The target geological parameters can be determined according to a geological detector. The geological parameters include, but are not limited to, composition of the rock, rock inclination, principal stress when the rock is damaged, and compressive strength.
In one embodiment, the target geological parameters and the surface area can be measured by a worker and then input into a terminal device.
And S102, determining the number and the positions of the blast holes according to the surface range.
It can be understood that when the number of the blast holes is too large, a large amount of manpower and material resources are consumed for punching; when the number of the blast holes is too small, the effect of blasting the area to be blasted is not ideal. Based on this, the terminal device may determine the area of the surface area; and then, determining the number and the positions of the blast holes according to the corresponding blasting ranges of the areas and the preset blast holes.
In one embodiment, the area may be determined by a worker measuring the area to be blasted. The blasting range is the range of blasting the ore rock required by the explosive in the blast hole after the explosion. Wherein the terminal device can determine the ratio of the area to the blasting range as the number of required blasting holes. Thereafter, one blast hole is provided every distance of two blast ranges.
When the area to be blasted is not a regular area (a regular area such as a square, a rectangle or a circle), the irregular blasting area can be divided to obtain the regular area and the divided area. Then, the number and the positions of the blast holes are determined for the regular area in the above mode, and the number and the positions of the blast holes for the irregular area can be determined by workers. Thus, the workload of workers can be reduced.
S103, determining a target blasting area corresponding to the blasting hole according to the position and the surface range of the blasting hole aiming at any blasting hole.
In one embodiment, the above S102 shows that the number and the positions of the blast holes are determined according to a preset blast range. Based on this, the terminal equipment can determine the ore rocks within the blasting range as the target blasting area.
S104, predicting target explosive quantity required to be set in the blast hole for blasting the target blasting area according to a first distance between the position of the blast hole and the central position of the surface range and target geological parameters of the target blasting area; the target explosive amount corresponding to the blasting holes with the small first distance is larger than the target explosive amount corresponding to the blasting holes with the large first distance.
In application, the target geological parameters corresponding to the target blasting regions are generally consistent, and therefore, in the present embodiment, the target blasting regions formed by different geological parameters are not specifically described.
In an embodiment, the terminal device may specifically determine the second distance between the location of the blast hole and the boundary according to the location of the blast hole and the boundary of the target blast area. Then, according to the incidence relation between the preset geological parameters and the vibration intensity, determining the target vibration intensity required to be generated by the explosive when the target blasting area is blasted; and determining the initial explosive amount according to the target distance, the target vibration strength and the target geological parameters. And finally, correcting the initial explosive quantity according to the first distance to obtain the target explosive quantity.
Specifically, the terminal device may first determine a separation distance between the location of the blast hole and each critical point of the boundary; thereafter, the maximum value of the separation distance is determined as the second distance. The terminal device can determine the spacing distance between the blast hole position and each critical point according to the existing distance measuring sensor.
In application, the target vibration intensity includes, but is not limited to, a vibration velocity, a vibration acceleration, a vibration frequency, and a vibration time of a vibration waveform caused by blasting. In this embodiment, the vibration frequency may be used as the target vibration intensity to represent the attenuation law of the target vibration intensity of the vibration caused by the blasting effect under different explosive quantities and different target distances.
In an embodiment, the terminal device may be preset with an association relationship between a preset geological parameter and a preset vibration intensity. Wherein, the preset vibration intensity can be considered as: the required vibration intensity of the explosive is produced when it is possible to blast an ore rock consisting of preset geological parameters. For example, the vibration strength required to damage a rock mass of different geological parameters may be determined according to known criteria for the failure of jointed rock masses.
Based on the above, the terminal device can determine the target vibration intensity required by the explosive when the to-be-blasted area is blasted according to the above association relationship after determining the target geological parameters of the to-be-blasted area.
In an embodiment, when the target vibration intensity is the vibration frequency, the terminal device may introduce the target distance, the target vibration intensity and the target geological parameter into a preset target calculation model to obtain an initial explosive amount; the target calculation model is as follows:
Figure BDA0003992191050000051
wherein f is the vibration frequency; k is a preset blasting method coefficient; k is a coefficient corresponding to the target geological parameter; q is the initial explosive quantity; r is the target distance.
When the target vibration intensity is the vibration frequency, the target calculation model may be:
Figure BDA0003992191050000061
wherein N is the vibration frequency, and z is a constant greater than 1.
And when the target vibration intensity is the vibration acceleration, the target calculation model may be:
Figure BDA0003992191050000062
where a is the vibration acceleration.
Based on the target calculation models respectively corresponding to the various target vibration intensities, it can be determined that: the vibration frequency generated during blasting is positively correlated with the initial explosive quantity and negatively correlated with the target distance. And under the condition that the target geological parameters are fixed, when the target distance is increased, the vibration acceleration generated during blasting with different initial explosive quantities is in a decreasing trend, the early-stage attenuation is faster, and the later-stage attenuation is slower and tends to be gentle. And, as the initial explosive quantity increases, the vibration acceleration at the same target distance increases. And under the condition that the target geological parameters are fixed, when the target distance is increased, the vibration frequency generated during blasting with the same initial explosive quantity is reduced, and the vibration frequency generated during blasting with different initial explosive quantities is in a descending trend.
In summary, the target calculation model can be used for representing the factor relationship between the target vibration strength and the target geological parameters, the initial explosive quantity and the target distance. That is, the target calculation model can be used for representing the attenuation law of the vibration intensity of explosives with different explosive quantities during blasting.
Based on the method, the terminal equipment can determine reasonable initial explosive quantity according to actual target geological parameters of the target blasting area so as to optimize the blasting effect of the target blasting area.
In addition, in order to fill the goaf as much as possible with the blasted ore rock, in this embodiment, the target explosive amount corresponding to the blast hole with the smaller first distance may be set to be larger than the target explosive amount corresponding to the blast hole with the larger first distance. That is, the target explosive amount of the blast hole at the position closer to the center of the surface area (the central region of the gob) is larger than the target explosive amount of the blast hole at the position farther from the center of the surface area.
It should be noted that, the ore rock at the central position on the goaf is blasted by adopting more target explosive amount, so that not only the ore rock near the central position after blasting is blasted, but also the blasted ore rock is filled into the goaf, and the filling effect on the goaf is improved.
It will be appreciated that even if a greater target explosive amount is blasted to generate a greater force of blasting the ore rock centrally on the goaf, the blasted ore rock will not typically be blasted out of the area to be blasted. Namely, the blasted ore rocks can be filled into the goaf as much as possible.
In a specific embodiment, the terminal device may determine, according to an association relationship between a preset distance range and a preset weight, a target weight corresponding to the distance range in which the first distance is located; then, the product of the target weight and the initial explosive amount is determined as the target explosive amount.
In this case, as is clear from the explanation of S104, the target weight for the blast hole having the smaller first distance needs to be greater than the target weight for the blast hole having the larger first distance.
In application, the association relationship between the preset distance range and the preset weight may be preset by a worker. In order to blast the region to be blasted, the maximum value of the target weight may be set to 1.1, and the minimum value may be set to 0.9. That is, the target charge at the blast hole having the smaller first distance will be greater than the initial charge.
It should be added that although the target explosive amount at the blast hole with the large first distance is smaller than the initial explosive amount, the complete blasting cannot be performed on the area to be blasted. However, since the target explosive amount at the blast hole having the small first distance is larger than the initial explosive amount, aftershocks generated during blasting of the explosive at the blast hole having the small first distance will affect the target blasting region corresponding to the blast hole having the large first distance. Further, the explosive at the blast hole having the first large distance can be assisted to blast the target blast area.
In this embodiment, the terminal device may determine a target geological parameter and a surface range of the region to be blasted above the gob, and determine the number and the positions of the blast holes according to the surface range. And then, aiming at any blast hole, determining a target blasting area corresponding to the blast hole according to the position and the surface range of the blast hole, and predicting the target explosive quantity required to be set in the blast hole for blasting the target blasting area according to the first distance between the position of the blast hole and the central position of the surface range and the target geological parameters of the target blasting area. Based on this, set up the quantity and the position of blast hole rationally according to the regional surface scope of waiting to explode, can avoid the quantity of blast hole to set up less, the interval between the adjacent blast hole is too big for the explosive only leads to near regional ore deposit in blast hole to be smashed thoroughly when the blasting, and the blasting effect of regional ore deposit in a distance is general. And because the area to be blasted is positioned above the goaf, when the target explosive quantity of the blast hole close to the central position of the area to be blasted is larger than the target explosive quantity of the blast hole far away from the central position, the ore rock near the central position after blasting can be blasted as far as possible, and the blasted ore rock is filled into the goaf, so that the filling effect on the goaf is improved.
In another embodiment, when blasting the ore rocks on the goaf, the ore rocks on the goaf are collapsed into the goaf as much as possible so as to improve the effect of filling the goaf. Based on the control, the terminal equipment can also control the blasting sequence of the explosives at each blasting hole.
Specifically, the terminal device may determine the blasting order of the explosives at each blast hole according to the first distance; the blasting sequence of the explosives at the blasting holes far away from the first distance is later than that of the explosives at the blasting holes near to the first distance. And then controlling the explosive at each blast hole according to the blasting sequence to blast.
It can be understood that the preferential blasting of the explosives in the blast holes at the first and second distances can cause the corresponding rock in the central area of the gob to collapse into the gob first. Then, when the explosives at other blast holes are blasted, because the ore rock in the central area is blasted, the impact force generated by blasting the explosives on the ore rock tends to the central area. Namely, the blasted ore rock can be filled to the center of the goaf as much as possible.
