煤层顺层钻孔煤炭自燃事故的分析与防范措施

Analysis and preventive measures of coal spontaneous combustion accident in coal seam bedding

随着瓦斯抽采在矿井瓦斯治理上的不断应用,许多高瓦斯矿井已经将瓦斯抽采作为瓦斯防治的治本之措,但煤层钻孔易发生钻孔煤炭自燃,对矿井的安全生产构成了严重的威胁。以东庞矿2902A工作面为例,介绍了高瓦斯矿井中自燃煤层顺层钻孔煤炭自燃的治理技术及防范措施,为其他类似矿井提供借鉴。

With the continuous application of gas drainage in mine gas control, many high gas mines adopted gas drainage as the root cause of gas prevention and control, but coal seam drilling was prone to borehole coal spontaneous combustion, which constituted safe production of mines, with serious security risk. The 2902A working face of Dongpang Mine was taken as an example, the treatment technology and preventive measures of spontaneous combustion of coal in the spontaneous combustion coal seam of high gas mine were introduced, which provided reference for other similar mines.
