锦瑞煤业8107孤岛工作面回采期间防灭火技术研究

Study on Fire Prevention Technology During Mining in 8107 Isolated Island Working Face of Jinrui Coal Industry

孤岛工作面受矿压集中、裂隙发育以及采面漏风严重等影响,开采期间煤层自燃发火危险性较大。对锦瑞煤业8107孤岛工作面回采期间面临的煤层自燃危险进行分析,并针对性地制定了防灭火技术措施。现场应用后,采面在回采期间未出现煤层自燃发火倾向,为煤炭安全高效回采创造了良好条件。

The isolated island working face is affected by the concentration of mine pressure, the development of fissures and the serious air leakage of the mining face, so the risk of spontaneous combustion of coal seam is high during mining. This paper analyzes the risk of spontaneous combustion of coal seam in 8107 isolated island working face of Jinrui coal industry during mining, and formulates the technical measures for fire prevention. After field application, there is no spontaneous combustion tendency of coal seam in the mining face during mining, which creates good conditions for safe and efficient mining of coal.
