in S301, a simulation test is performed on the three-dimensional model of the rock mass corresponding to each initial layout result, so as to obtain a rock mass blasting result.
In this embodiment, the rock burst result is used to describe the damage condition of the target rock mass after the simulation test.
In one embodiment of the present application, the terminal device may specifically determine the rock burst result through S401 to S402 as shown in fig. 6, which is described in detail as follows:
in S401, after performing a simulation test on the three-dimensional model of the rock mass, a cross-sectional view at a first set position of the three-dimensional model of the rock mass is acquired.
In S402, the rock mass blasting result is determined from the sectional view.
In this embodiment, in order to determine the damage condition of the target rock mass, the terminal device may establish a section at a first set position of the three-dimensional model of the rock mass, so as to obtain a section view at the first set position of the three-dimensional model of the rock mass, and determine a blasting result of the rock mass according to the section view. The sectional view shows damage condition of the target rock mass after the simulation test.
The cross-sectional view specifically refers to a plan view obtained by cutting the three-dimensional model of the rock mass in a direction parallel to the ground with the first set position as a starting point.

In S502, a vibration velocity profile is constructed from the vibration velocity set.
In S503, the result of the vibration of the filling body is determined according to the vibration velocity profile.
In practical application, in the three-dimensional model of the filler, the stress wave superposition function proves that the filler is most severely damaged on the centre line of the blast hole of the symmetrical plane, so that the terminal equipment can determine any point on the centre line of the blast hole of the symmetrical plane as the second setting position.
In this embodiment, the terminal device may acquire a vibration velocity set of the second set position of the three-dimensional model of the filler, and construct a vibration velocity graph according to the vibration velocity set, so that the terminal device may determine a vibration result of the filler according to the vibration velocity graph.
Specifically, the terminal device may determine the result of the vibration of the filling body according to the following steps, which are described in detail below:

and determining the vibration result of the filling body according to the vibration speed peak value.
In this embodiment, after obtaining the vibration velocity profile, the terminal device may determine the vibration velocity peak value at the second set position according to the vibration velocity profile in the vibration velocity profile.
After the terminal equipment obtains the vibration speed peak value, whether the vibration speed peak value exceeds the standard or not can be determined according to the explosion vibration safety permission standard, and then the vibration result of the filling body is obtained.
Specifically, the terminal device may compare the above-mentioned vibration speed peak value with a third threshold value. Wherein the third threshold may be determined according to a standard speed specified in the blast vibration safety allowance standard.
In one embodiment of the present application, when the terminal device detects that the vibration speed peak value is greater than or equal to the third threshold value, the vibration speed peak value is indicated to be out of standard, so that it can be determined that the vibration result of the filling body is out of standard, that is, the damage to the filling body is serious.
In another embodiment of the present application, when the terminal device detects that the vibration speed peak value is smaller than the third threshold value, it indicates that the vibration speed peak value is not out of standard, so that it can be determined that the vibration result of the filling body is that the vibration is not out of standard, that is, the damage to the filling body is not serious.
In S303, according to the rock mass blasting result and the filling body vibration result, a blasting test result corresponding to each initial layout result is determined.
In this embodiment, after obtaining the rock blasting result and the filling body vibration result corresponding to each initial layout result, the terminal device may determine the blasting test result corresponding to each initial layout result according to the rock blasting result and the filling body vibration result.
Specifically, the terminal device may determine the blasting test result corresponding to each initial layout result through the following steps, which are described in detail as follows:
determining a first weight corresponding to the rock mass blasting result and a second weight corresponding to the filling body vibration result;
and determining the explosion test result according to the rock mass explosion result, the filling body vibration result, the first weight and the second weight.
In this embodiment, the terminal device may determine the first weight and the second weight according to respective degrees of influence corresponding to the rock mass blasting result and the filling body vibration result.
Specifically, when the influence degree of the rock mass blasting result is greater than the influence degree of the filling body vibration result, the first weight is greater than the second weight; when the influence degree of the rock mass blasting result is smaller than that of the filling body vibration result, the first weight is smaller than the second weight; when the influence degree of the rock mass blasting result is consistent with the influence degree of the filling body vibration result, the first weight is equal to the second weight.
It should be noted that the sum of the first weight and the second weight is equal to 1.
In S104, a target layout result is selected from the at least one initial layout result according to the blasting test result.
In this embodiment of the present application, after obtaining a blasting test result corresponding to each initial layout result, the terminal device may select, according to the blasting test result, a target layout result of the blasthole from at least one initial layout result.
In some possible embodiments, the terminal device may determine, as the target layout result, an initial layout result in which the rock burst result indicates that the target rock is severely damaged and the filler vibration result indicates that the filler is not severely damaged, from among burst test results corresponding to each initial layout result.
The above can be seen that, according to the method for arranging the blastholes provided by the embodiment of the application, at least one initial arrangement result of the blastholes aiming at the target rock mass is obtained, and the blastholes refer to holes in the target rock mass for placing explosives; constructing a three-dimensional model corresponding to each initial layout result by utilizing finite element analysis software; performing a blasting simulation test on the three-dimensional model corresponding to each initial layout result to obtain a blasting test result corresponding to each initial layout result; and selecting a target layout result from at least one initial layout result according to the blasting test result.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
