煤炭自燃高温点的检测与判定是矿井火灾防治的基础工作，也是矿井防灭火方案制定的前提。利用红外热像仪测试煤巷壁面煤体温度场分布，排查全断面高温点，找出近巷煤体高温点；依据巷道壁面与巷道风流的温度差，确定煤巷高温区域。探测显示，煤巷高温区域主要集中在断层带附近，由此可知巷道煤体破碎、漏风是导致煤炭自热的主要原因。在此基础上制定了向高温区域打钻压注 MEA(一种商业高分子材料)封堵剂的治理措施，使得高温区域钻孔内 CO 浓度从100~160 ppm(0.0045~0.0071 mol/m3)降至10 ppm(0.00045 mol/m3)，有效地降低了煤巷温度，为矿井防灭火提供了依据。

As the basic work of fire prevention and control in coal mines, detecting and finding out the high temperature area are one of the preconditions of making fire prevention plan. In this paper, the temperature field of coal wall in roadway is tested by infrared thermal imaging, and the high temperature area of the coal is checked out compared with airflow temperature. The result shows that the high temperature area is mainly concentrated nearby a fault zone, from which it can be known that the crushed coal and air leakage are the major causes to induce spontaneous combustion. According to this finding, the measures of injecting MEA into the high temperature area have been taken, making CO content decrease from 100~160 ppm to10 ppm.
