| الوصف: | In this paper, the deep hole and shallow hole temperature measurement technology is used to measure the rock temperature in No.13 mining area of Yangchangwan Coal Mine, and the cooling circle range of 937 m elevation roadway for the return air downhill in No.13 mining area and 430 m elevation roadway for the auxiliary transportation downhill in No.13 mining area are determined. The COMSOL software is used to analyze the surrounding rock temperature distribution, and the reliability of the surface borehole temperature measurement data is verified according to the temperature measurement results. Combined with the ground borehole temperature measurement data and the deep hole and shallow hole temperature measurement results, the ground temperature gradient and the heat damage area are defined, which provides a basis for the subsequent heat damage treatment. |
