摘　　要：通过对封闭火区使用示踪气体CF2Cl Br法圈定封闭工作面遗留高温火源点的钻孔范围,对该钻孔范围进行取气样利用Tr指标验证其可靠性,然后运用碳的氧化物比率CO/CO2指标法分析每个可靠性钻孔气体的自燃发展状态,进一步缩小范围,准确定位火区位置,有效解决了潞安新疆煤化工(集团)有限公司二矿w4204工作面封闭火区治理过程因气体紊乱无法判别高温火源点的问题。Have effectively solved the question of unable to distinguish high temperature fire point caused by gas disorder on Lu＇an Xinjiang coal chemical industry （group） Co., Ltd.. Second mine w4204 working face, by using the tracer gas CF2ClBr method selects closed legacy high temperature fire point of drill hole, taking the sample gas Tr to verify its reliability indicators, then use carbon oxide ratio of CO/COg index method analysis the development state of spontaneous combustion of the gas drilling, narrowed scope, accurated the position of fire area, and it has introduced the mine fire prevention work smoothly.
