摘　　要：利用深孔、浅孔测温技术对羊场湾煤矿13采区的岩温进行测定,确定了13采区回风下山937 m高程巷道和13采区辅运下山430 m高程巷道的冷却圈范围,并利用COMSOL软件分析其围岩温度分布状况,根据测温结果验证了地面钻孔测温数据的可靠性;结合地面钻孔测温数据和深孔、浅孔测温结果,明确了地温梯度及热害区域,为后序的热害治理提供了依据。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.
