Description

Technical Field

[0001] This application belongs to the field of mine safety technology, and in particular relates to a method, apparatus, terminal equipment and computer-readable storage medium for determining hole spacing. Background Technology

[0002] In mining production, a large number of development and preparation roadways need to be excavated each year. The excavation speed and efficiency of these roadways have a significant impact on the sustainability of mining production and cost control. Since each roadway has only one free face, blasting is subject to significant clamping forces. Therefore, it is necessary to create free faces for other blast holes using cut-out blasting. These cut-out blasting holes include cut holes and empty holes. The success of cut-out blasting is closely related to the spacing between the cut holes and empty holes.

[0003] Current technology typically determines the spacing between cut holes and hollow holes simply based on the fragmentation ring formed by the combined action of stress waves and explosive gases generated during blasting. This approach is not comprehensive enough, resulting in low accuracy in determining the spacing between cut holes and hollow holes. Summary of the Invention

[0057] Please see Figure 1 , Figure 1This is a flowchart illustrating the implementation of a method for determining hole spacing according to an embodiment of this application. In this embodiment, the execution subject of the method for determining hole spacing is a terminal device. The terminal device can be a laptop, computer, or other similar device.

[0058] like Figure 1 As shown, the method for determining the hole spacing provided in one embodiment of this application may include S101 to S105, which are detailed below:

[0059] In S101, the first area of ​​the rock mass to be blasted, the first diameter of the slot hole, the second diameter of the cavitation hole, and the depth of the blast hole are obtained.

[0060] In this embodiment of the application, a blast hole refers to a hole drilled in the rock mass to be blasted, used to fill explosives for blasting. In other words, the blast hole depth refers to the depth of the slotted hole and the depth of the empty hole. Among them, the depth of the slotted hole and the depth of the empty hole are the same.

[0061] In one embodiment of this application, the terminal device can specifically be configured as follows: Figure 2 S201 to S204, as shown, determine the first diameter of the slotted hole and the second diameter of the hollow hole, as detailed below:

[0062] In S201, a first image containing the rock mass to be blasted and a second image of the area where the rock mass to be blasted is located are acquired.

[0063] In this embodiment, both the rock mass to be blasted and the area where the rock mass is located are equipped with camera devices. Therefore, the camera device located on the rock mass to be blasted can acquire a first image containing the rock mass to be blasted, and the camera device located in the area where the rock mass to be blasted is located can acquire a second image containing the area.

[0064] Based on this, the terminal device can acquire the first image and the second image through the aforementioned camera device.

[0065] In S202, the lithology of the location of the rock mass to be blasted is determined based on the first image.

[0066] In practical applications, lithology refers to some properties that reflect the characteristics of rocks, such as color, composition, structure, cement, cement type, and special minerals.

[0067] In this embodiment, the terminal device can determine the lithology of the rock at the location of the rock mass to be blasted based on the first image described above.

[0068] In S203, the state information of the region is determined based on the second image.

[0069] In this embodiment, the status information is used to describe the internal conditions of the area where the rock mass to be blasted is located.

[0070] In S204, the first diameter and the second diameter are determined based on the state information and the lithology.

[0071] Since an excessively large borehole diameter can cause misalignment and blockage of the cut hole and / or the empty hole after drilling, in this embodiment, the terminal device needs to determine the first diameter of the cut hole and the second diameter of the empty hole based on the lithology of the rock at the location of the rock mass to be blasted and the internal conditions of the area where the rock mass to be blasted is located.

[0072] In S102, the compensation space corresponding to the rock mass to be blasted is determined based on the first area.

[0073] In practical applications, compensation space refers to the space carved out in a ore block to accommodate the volume of rock fragments that will burst out before blasting.

[0074] Based on this, in one embodiment of this application, the terminal device can specifically calculate the compensation space corresponding to the rock mass to be blasted according to the following formula:

[0075] V = S1K;

[0076] Where V represents the compensation space corresponding to the rock mass to be blasted, S1 represents the first area of ​​the rock mass to be blasted, and K represents the rock fragmentation coefficient.

[0077] It should be noted that the rock fragmentation coefficient can be 1.3.

[0078] Please see Figure 3 , Figure 3 This is a geometric diagram showing the distance between the slotted hole and the hollow hole provided in an embodiment of this application. For example... Figure 3 As shown, circle A is the circle corresponding to the empty hole, circle B is the circle corresponding to the slotted hole, d is the first diameter of the slotted hole, D is the second diameter of the empty hole, S2 is the second area of ​​the empty hole, S3 is the third area of ​​the slotted hole, L is the hole spacing between the slotted hole and the empty hole, and the shaded area is the first area of ​​the rock mass to be blasted.

[0079] Based on this, in another embodiment of this application, combined with Figure 3 The terminal equipment can calculate the first area of ​​the rock mass to be blasted using the following formula:

[0080]

[0081] Where S1 represents the first area of ​​the rock mass to be blasted, L represents the hole spacing between the cut hole and the empty hole, d represents the first diameter of the cut hole, and D represents the second diameter of the empty hole.

[0082] In S103, the first radius of the crushing ring formed after the rock mass to be blasted is destroyed, and the second radius of the fracture ring are determined based on the first diameter.

[0083] In practical applications, the crushing ring and the fissure ring both refer to the concentric circles that propagate outward from the explosive charge when the explosive is used to blast the rock mass to be blasted, which are generated by the expansion force and shock wave.

[0084] In this embodiment, the first radius of the crushing ring is a first preset multiple of the radius of the slotted hole, and the second radius of the crack ring is a second preset multiple of the radius of the slotted hole. The first preset multiple is less than the second preset multiple.

[0085] For example, the first preset multiple can be 2 to 3 times, and the second preset multiple can be 10 to 15 times.

[0086] In S104, the offset during drilling is calculated based on the borehole depth.

[0087] In this embodiment, the terminal device can calculate the offset according to the following formula:

[0088]

[0089] Where l represents the offset, H represents the borehole depth, μ represents the borehole deviation coefficient, and η represents the borehole deviation rate. The borehole deviation coefficient can be 0.5.

[0090] In S105, the hole spacing between the slotted hole and the hollow hole is determined based on the compensation space, the first diameter, the second diameter, the first radius, the second radius, and the offset.

[0091] In practical applications, the spacing between the slotted hole and the empty hole is usually affected by the compensation space corresponding to the rock mass to be blasted, the explosive breaking range, and the borehole deviation. Therefore, in this embodiment, the terminal device can determine the spacing between the slotted hole and the empty hole based on the compensation space corresponding to the rock mass to be blasted, the first diameter of the slotted hole, the second diameter of the empty hole, the first radius of the crushing ring, the second radius of the fracture ring, and the offset.

[0092] In one embodiment of this application, the terminal device can specifically be configured as follows: Figure 4 S301 to S304, as shown, determine the hole spacing between the slotted hole and the empty hole, as detailed below:

[0093] In S301, a first range of values ​​for the hole spacing is determined based on the compensation space, the first diameter, and the second diameter.

[0094] It should be noted that in practical applications, the compensation space corresponding to the rock mass to be blasted should meet the volume required after the rock mass to be blasted is destroyed; otherwise, a "crushing" phenomenon will occur, which will affect the blasting effect. Therefore, in this embodiment, the terminal device can determine the first range of the hole spacing between the slotted hole and the empty hole based on the compensation space corresponding to the rock mass to be blasted, the first diameter of the slotted hole, and the second diameter of the empty hole.

[0095] In one embodiment of this application, the terminal device may determine the first range of values ​​for the hole spacing according to the following formula:

[0096]

[0097] Wherein, L1 represents the first range of the above hole spacing, D represents the second diameter of the empty hole, d represents the first diameter of the slotted hole, K represents the rock fragmentation coefficient, S1 represents the first area of ​​the rock mass to be blasted, S2 represents the second area of ​​the empty hole, S3 represents the third area of ​​the slotted hole, and V represents the compensation space corresponding to the rock mass to be blasted.

[0098] In S302, a second range of values ​​for the hole spacing is determined based on the second diameter, the first radius, and the second radius.

[0099] It should be noted that in practical applications, the explosive energy generated during blasting should meet the energy requirements for blasting the rock mass to be blasted. Otherwise, if the amount of explosive is too small, the rock mass to be blasted will not be fully blasted, and if the amount of explosive is too large, the hole punching phenomenon will occur. Therefore, in this embodiment, the terminal equipment needs to determine the second range of hole spacing based on the second diameter of the hole, the first radius of the crushing ring, and the second radius of the fracture ring.

[0100] In one embodiment of this application, the terminal device may specifically determine the second range of hole spacing according to the following formula:

[0101]

[0102] Where L2 represents the second range of hole spacing, D represents the second diameter of the pore, r1 represents the first radius of the crushing ring, and r2 represents the second radius of the crack ring.

[0103] In S303, a third range of values ​​for the hole spacing is determined based on the offset, the first diameter, and the second diameter.

[0104] It should be noted that in practical applications, the hole spacing between the slotted hole and the empty hole needs to be greater than the offset generated during drilling in order to avoid the mutual penetration between adjacent blast holes as much as possible. Therefore, in this embodiment, the terminal device can determine the third range of hole spacing based on the offset, the first diameter of the slotted hole and the second diameter of the empty hole.

[0105] In one embodiment of this application, the terminal device may specifically determine the third range of hole spacing values ​​according to the following formula:

[0106]

[0107] Where L3 represents the third range of hole spacing, D represents the second diameter of the hole, d represents the first diameter of the slotted hole, l represents the offset, H represents the borehole depth, μ represents the borehole deviation coefficient, and η represents the borehole deviation rate.

[0108] In S304, the hole spacing is determined based on the first value range, the second value range, and the third value range.

[0109] In this embodiment, after obtaining the first, second, and third ranges of the hole spacing between the slotted hole and the hollow hole, the terminal device can randomly select a value from the above ranges as the hole spacing.

[0110] In one embodiment of this application, the terminal device may also determine the hole spacing according to the following method, as detailed below:

[0111] Determine the intersection of the first value range, the second value range, and the third value range;

[0112] The hole spacing is determined based on the intersection and multiple set spacings.

[0113] In this embodiment, the terminal device can determine the intersection of the first value range, the second value range, and the third value range, and determine a value that satisfies the intersection from multiple set spacings based on the intersection, and determine the value as the hole spacing between the slotted hole and the empty hole. The set spacing can be set according to actual needs and is not limited here.

[0114] As can be seen from the above, the method for determining hole spacing provided in this application involves obtaining the first area of ​​the rock mass to be blasted, the first diameter of the slotted hole, the second diameter of the empty hole, and the depth of the blast hole; determining the compensation space corresponding to the rock mass to be blasted based on the first area; determining the first radius of the crushed ring and the second radius of the fracture ring formed after the rock mass to be blasted is broken based on the first diameter; calculating the offset during drilling based on the first diameter, the second diameter, and the depth of the blast hole; and determining the hole spacing between the slotted hole and the empty hole based on the compensation space, the first diameter, the second diameter, the first radius, the second radius, and the offset. Compared with the prior art that determines the hole spacing only based on the crushed ring, this application combines multiple parameters such as the compensation space of the rock mass to be blasted, the diameter of the slotted hole, the diameter of the empty hole, the radius of the crushed ring, the radius of the fracture ring, and the offset to determine the hole spacing, which can improve the accuracy of the determined hole spacing.

[0115] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
