[0056] Please see Figure 1 , Figure 1This is a flowchart illustrating the implementation of a borehole layout method according to an embodiment of this application. In this embodiment, the execution subject of the borehole layout method is a terminal device.
[0057] like Figure 1 As shown, the borehole layout method provided in one embodiment of this application may include S101 to S104, which are detailed below:
[0058] In S101, at least one initial layout result of boreholes for the target rock mass is obtained, wherein the boreholes refer to holes in the target rock mass for placing explosives.
[0059] It should be noted that the target rock mass refers to the rock mass that needs to be blasted.
[0060] In this embodiment of the application, in order to improve the blasting effect on the target rock mass, it is necessary to arrange the positions of multiple blast holes in the target rock mass.
[0061] The initial layout result refers to the position information of each of the multiple blast holes, which can be represented by coordinates.
[0062] In one implementation of this application, the terminal device can obtain at least one initial layout result of the plurality of blast holes in real time through a server connected to it via wireless / wired communication. The server can be a computer, desktop computer, or other similar device.
[0063] In another implementation of this application, the terminal device can pre-obtain at least one initial layout result of the plurality of blast holes and store it in its own memory. When the terminal device needs to obtain the initial layout result, it retrieves at least one initial layout result of the blast holes from its own memory.
[0064] In practical applications, voids can create favorable conditions for blasting of boreholes. Voids can not only cause stress concentration effects, but also facilitate the breaking of rocks by reflected tensile waves. Therefore, voids need to be set in the target rock mass, and the terminal equipment can determine at least one initial layout result of the borehole based on the relevant information of the void.
[0065] Specifically, in one embodiment of this application, the terminal device can be configured as follows: Figure 2 The steps S201 to S202 shown determine at least one initial layout result for the boreholes, as detailed below:
[0066] In S201, the diameter and / or number of cavities in the target rock mass are obtained, where the cavities refer to holes in the target rock mass where no explosives are placed.
[0067] In S202, the at least one initial layout result is determined based on the aperture and / or number of apertures.
[0068] In one embodiment of this application, when the terminal device detects that the number of holes is greater than a first threshold and the diameter of the holes is less than a second threshold, it can determine that the initial layout of the boreholes is a four-hole layout, a nine-hole layout, or a sixteen-hole layout, etc. The first and second thresholds can be set according to actual needs and are not limited here. For example, the first threshold can be set to 1, and the second threshold can be set to 64mm.
[0069] It should be noted that the aperture of the pore specifically refers to the diameter of the pore.
[0070] In this embodiment, in the four-hole layout, nine-hole layout, and sixteen-hole layout, each blast hole is adjacent to an empty hole, and the distance between any two adjacent holes is equal.
[0071] For example, using a nine-hole layout, please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of the nine-hole layout provided in an embodiment of this application. For example... Figure 3 As shown, dot A represents a blast hole, and dot B represents an empty hole.
[0072] In another embodiment of this application, when the terminal device detects that the number of holes is equal to a first threshold, it can determine that the initial layout result of the boreholes is a borehole surround layout. Here, borehole surround layout refers to a layout in which multiple boreholes are arranged in concentric circles surrounding the holes, with the holes as the centers.
[0073] It should be noted that in the borehole surround layout, the distance between any two adjacent boreholes is equal.
[0074] For example, using five blast holes, please refer to [link / reference]. Figure 4 , Figure 4 This is a schematic diagram of the borehole surround layout provided in an embodiment of this application. Figure 4 As shown, dot A represents a blast hole, and dot B represents an empty hole.
[0075] In S102, a three-dimensional model corresponding to each of the initial layout results is constructed using finite element analysis software.
[0076] In practical applications, finite element analysis software is a computer-aided structural design software based on structural mechanics analysis. It was first applied as an effective numerical analysis method in the field of continuum mechanics—specifically in the static and dynamic characteristic analysis of aircraft structures—and subsequently quickly gained widespread use in solving continuous problems such as heat conduction, electromagnetic fields, and fluid mechanics. Finite element analysis software includes, but is not limited to, ABAQUS, ANSYS, and MSC.
[0077] In this embodiment of the application, the three-dimensional model includes, but is not limited to, a three-dimensional model of rock mass and a three-dimensional model of infill body.
[0078] In S103, a blasting simulation test is performed on the three-dimensional model corresponding to each initial layout result to obtain the blasting test results corresponding to each initial layout result.
[0079] In one embodiment of this application, since the three-dimensional model includes, but is not limited to, a three-dimensional model of rock mass and a three-dimensional model of infill body, the terminal device can specifically be configured as follows: Figure 5 The S301 to S303 shown below determine the blasting test results corresponding to each initial layout result, as detailed below:
[0080] In S301, a simulation test is performed on the three-dimensional rock mass model corresponding to each initial layout result to obtain the rock mass blasting result.
[0081] In this embodiment, the rock blasting results are used to describe the damage to the target rock mass after the simulation test.
[0082] In one embodiment of this application, the terminal device can specifically be configured as follows: Figure 6 The results of rock blasting, as shown in S401 to S402, are detailed below:
[0083] In S401, after conducting a simulation test on the three-dimensional rock mass model, a cross-sectional view is obtained at a first set position on the three-dimensional rock mass model.
[0084] In S402, the rock mass blasting result is determined based on the cross-sectional view.
[0085] In this embodiment, to clarify the damage status of the target rock mass, the terminal device can establish a cross-section at a first predetermined location on the three-dimensional model of the rock mass to obtain a cross-sectional view at the first predetermined location on the three-dimensional model of the rock mass, and determine the rock mass blasting result based on the cross-sectional view. The aforementioned cross-sectional view illustrates the damage status of the target rock mass after the simulation test.
[0086] It should be noted that the cross-sectional view specifically refers to the planar view obtained by cutting the three-dimensional rock mass model along a direction parallel to the ground, starting from the first set position.
[0087] In one embodiment of this application, in order to improve the accuracy of rock blasting results, the first set position may include, but is not limited to, the position of the borehole opening, the position of the borehole center, and the position of the borehole bottom.
[0088] In S302, a simulation test is performed on the three-dimensional model of the filling body corresponding to each initial layout result to obtain the vibration results of the filling body.
[0089] In this embodiment, the vibration results of the filling body are used to describe the damage to the filling body caused by blasting during the simulation test, that is, the degree of vibration of the filling body.
[0090] In one embodiment of this application, the terminal device can specifically be configured as follows: Figure 7 The vibration results of the filling body as shown in S501 to S503 are detailed below:
[0091] In S501, during the simulation test of the three-dimensional model of the filling body, the vibration velocity set of the second set position of the three-dimensional model of the filling body is obtained; the vibration velocity set includes the vibration velocity of the second set position of the three-dimensional model of the filling body at each time.
[0092] In S502, a vibration velocity curve is constructed based on the vibration velocity set.
[0093] In S503, the vibration result of the filling body is determined based on the vibration velocity curve.
[0094] In practical applications, in the three-dimensional model of the filling body, it can be seen from the superposition of stress waves that the filling body is most severely damaged on the borehole centerline of the symmetry plane. Therefore, the terminal equipment can determine any point on the borehole centerline of the symmetry plane as the second set position.
[0095] In this embodiment, the terminal device can obtain the vibration velocity set at the second set position of the three-dimensional model of the filling body, and construct a vibration velocity curve based on the vibration velocity set, so that the terminal device can determine the vibration result of the filling body based on the vibration velocity curve.
[0096] Specifically, the terminal equipment can determine the vibration results of the filling body according to the following steps, detailed below:
[0097] The peak vibration velocity at the second set position is determined based on the vibration velocity curve.
[0098] The vibration result of the filling material is determined based on the peak vibration velocity.
[0099] In this embodiment, after obtaining the vibration velocity curve, the terminal device can determine the peak vibration velocity at the second set position based on the vibration velocity curve in the vibration velocity curve.
[0100] After obtaining the peak vibration velocity, the terminal equipment can determine whether the peak vibration velocity exceeds the standard according to the safety allowable standard for blasting vibration, and thus obtain the vibration result of the filling body.
[0101] Specifically, the terminal equipment can compare the aforementioned peak vibration velocity with a third threshold. The third threshold can be determined based on the standard velocity specified in the blasting vibration safety allowable standard.
[0102] In one embodiment of this application, when the terminal device detects that the peak vibration velocity is greater than or equal to a third threshold, it indicates that the peak vibration velocity exceeds the standard, thereby determining that the vibration result of the filling body is excessive, that is, the filling body is severely damaged.
[0103] In another embodiment of this application, when the terminal device detects that the peak vibration velocity is less than the third threshold, it indicates that the peak vibration velocity has not exceeded the standard, thereby determining that the vibration result of the filling body is not excessive, that is, the damage to the filling body is not serious.
[0104] In S303, based on the rock blasting results and the filling vibration results, the blasting test results corresponding to each initial layout result are determined.
[0105] In this embodiment, after obtaining the rock blasting results and filling vibration results corresponding to each initial layout result, the terminal device can determine the blasting test results corresponding to each initial layout result based on the rock blasting results and filling vibration results.
[0106] Specifically, the terminal device can determine the blasting test results corresponding to each initial layout result through the following steps, detailed below:
[0107] Determine the first weight corresponding to the rock mass blasting result and the second weight corresponding to the filling body vibration result;
[0108] The blasting test results are determined based on the rock blasting results, the filling body vibration results, the first weight, and the second weight.
[0109] In this embodiment, the terminal device can determine the first weight and the second weight based on the respective influence of the rock blasting results and the vibration results of the filling body.
[0110] Specifically, when the impact of the rock mass blasting result is greater than the impact of the filling body vibration result, the first weight is greater than the second weight; when the impact of the rock mass blasting result is less than the impact of the filling body vibration result, the first weight is less than the second weight; when the impact of the rock mass blasting result is the same as the impact of the filling body vibration result, the first weight is equal to the second weight.
[0111] It should be noted that the sum of the first weight and the second weight is equal to 1.
[0112] In S104, a target layout result is selected from the at least one initial layout result based on the blasting test results.
[0113] In this embodiment of the application, after obtaining the blasting test results corresponding to each initial layout result, the terminal device can select the target layout result of the blast hole from at least one initial layout result based on the blasting test results.
[0114] In some possible embodiments, the terminal device can determine the initial layout result as the target layout result from the blasting test results corresponding to each initial layout result, where the rock blasting result indicates severe damage to the target rock mass and the filling vibration result indicates that the filling body is not severely damaged.
[0115] As can be seen from the above, the borehole layout method provided in this application involves obtaining at least one initial layout result for boreholes in a target rock mass (a borehole refers to a hole in the target rock mass where explosives are placed); constructing a three-dimensional model corresponding to each initial layout result using finite element analysis software; conducting blasting simulation tests on the three-dimensional model corresponding to each initial layout result to obtain blasting test results corresponding to each initial layout result; and selecting a target layout result from at least one initial layout result based on the blasting test results. Compared with the prior art, which only uniformly arranges a certain number of boreholes, the method provided in this application requires determining the target layout result of the boreholes based on the blasting test results corresponding to each initial layout result, thereby improving the accuracy of borehole layout and thus improving the blasting effect.
[0116] 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.
