As an example, taking the average uniaxial compressive strength of 19MPa as an example, the comprehensive lithology of the rock strata between the upper coal seam layer and the lower coal seam layer is determined to be weak.
TABLE 2 lithology discrimination table between upper and lower coal seam layers
S2: and acquiring a second mining influence multiple based on the comprehensive lithology.
In some embodiments of the present application, when the comprehensive lithology between the upper and lower coal seam layers is hard, the value of the feasible mining impact multiple may be 8; when the comprehensive lithology between the upper coal seam layer and the lower coal seam layer is medium hard, the value of the feasible mining influence multiple can be 7.5; when the comprehensive lithology between the upper coal seam layer and the lower coal seam layer is weak, the value of the feasible mining influence multiple can be 7.
As an example, if the comprehensive lithology of the rock stratum between the upper and lower coal strata is weak, the feasible mining impact multiple is 7.
S3: and comparing the second mining influence multiple with the mining ratio, and selecting the larger one as a threshold value of the feasible mining influence multiple.

Step S206: and determining an upgoing mining feasible area and an upgoing mining infeasible area in the upgoing mining demonstration area based on the contour map of mining influence factors of the upgoing mining demonstration area.
In the embodiment of the present application, step S206 may be implemented by any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.
By implementing the embodiment of the application, the first mining influence multiple of the drill hole and the feasible mining influence multiple threshold value of the upward mining can be obtained based on the obtained data, so that the contour map of the mining influence multiple of the upward mining demonstration area is drawn based on the drill hole coordinate, the boundary coordinate, the mining influence multiple and the feasible mining influence multiple threshold value, the upward mining demonstration area is divided, the upward mining feasible area and the upward mining infeasible area are determined, safety technical measures can be conveniently taken aiming at the upward mining infeasible area, and the safety and the economy of the upward mining are ensured.

By way of example, referring to FIG. 3, FIG. 3 is an exemplary up production demonstration zone mining factor contour map provided by an embodiment of the present application. As shown in fig. 3, taking the threshold of the feasible mining influence factor as 7 as an example, the contour map of the mining influence factor of the upgoing mining demonstration area includes: the method comprises the following steps of (1) an isoline corresponding to a mining influence multiple threshold value 7, (2) an upper coal seam mining boundary line, (3) a lower coal seam mining boundary line, (4) a mining influence multiple isoline and a corresponding mining influence multiple, and (5) drilling hole numbering and mining thickness. And the area surrounded by the lower coal seam mining boundary line and the contour line corresponding to the feasible mining influence multiple threshold value 7 is the feasible area for upward mining. And a region (namely, a region indicated by oblique line shading in fig. 3) surrounded by the contour line corresponding to the stoping possible boundary factor threshold 7 of the lower coal seam is an upgoing mining infeasible region.
Referring to fig. 4, fig. 4 is a flowchart of a method for determining feasibility of upward mining according to an embodiment of the present disclosure. As shown in fig. 4, the method may include, but is not limited to, the following steps.

For example, the mining impact multiple of each borehole is calculated based on the upper and lower seam spacing and the lower seam thickness of each borehole.
Step S403: and drawing a contour map of the mining influence multiple by using Surfer software.
For example, a kriging difference method is adopted, and a Surfer software is used for drawing a contour map of the mining influence multiple.
Step S404: a threshold for feasible upwelling is determined.
