复杂环境下采煤工作面综合防灭火技术的实践与应用
Comprehensive Fire Prevention and Extinguishment in Coal Mining Face under Complex Environment Practice and Application of Technology

鹤煤公司五环分公司，煤与瓦斯突出矿井，列入2018年去产能关闭退出矿井计划。井田范围内有一向斜构造，向斜两翼伴生断层较多，煤层为三级不易自燃煤层。矿井采空区多，构造应力大，煤层裂隙发育，易发生煤层自燃，影响矿井安全生产。为此，根据矿井实际条件，采取了针对性综合防灭火技术，取得了良好的效果，促进了安全生产和效益保证。
The coal and gas outburst mine of the Fifth Ring Branch of the Crane Coal Company was listed in the 2018 plan to shut down and exit the mine. There is a syncline structure within the scope of the mine field. There are many associated faults on both wings of the syncline. The coal seam is a Class III coal seam that is not easy to spontaneous combustion. There are many goafs in the mine, the tectonic stress is large, the coal seam cracks are developed, and the spontaneous combustion of the coal seam is easy to occur, affecting the safe production of the mine. Therefore, according to the actual conditions of the mine, the targeted comprehensive fire prevention and extinguishing technology has been adopted, and good results have been achieved, promoting safe production and benefit assurance.
