为了能够更好的应对煤矿深度开采带来的煤层自然发火的严峻形势,在对现有矿井防灭火技术进行分析的基础上,结合工作面现场情况和煤氧化实验,提出了以采空区局部温度、指标气体监测为主,以注浆防灭火、构筑防漏风隔离墙为辅,以及发现隐情及时施工高位钻孔,进行注胶的综合防灭火技术措施,并对各个措施进行了合理优化设计,通过在煤矿现场应用,经测定,回风巷及隅角CO浓度稳定在0~21×10-6之间,取得了良好的效果。
In order to be able to cope with the severe situation of spontaneous combustion of coal seam caused by deep mining in coal mines, based on the analysis of the existing mine fire extinguishing technology, combined with the scene of the working face and coal oxidation experiments, Temperature and index gas monitoring, grouting anti-fire and building air leakage isolation wall as a supplement, as well as the detection of hidden danger and timely construction of high-level drilling, plastic injection of a comprehensive fire prevention and control measures, and the various measures of rational design optimization Through the application in the coal mine, it was determined that the concentration of CO in the return airway and the corner was stable between 0 and 21 × 10-6, and achieved good results.
