高位钻孔瓦斯抽放工作面自燃防治方案探讨

Discussion on Prevention and Control Scheme of Spontaneous Combustion in Gas Drainage Working Face with High Location

通过对高位钻孔抽放综放工作面的自燃隐患进行分析,提出了自燃防治的综合措施,在充分考虑采空区瓦斯涌出和高位钻孔瓦斯抽放对自燃影响的情况下从正常回采过程、工作面推进缓慢时、放煤口附近区域、停采撤架期间等4个方面进行自燃防治方案的探讨,可为高位钻孔瓦斯抽放综放面自燃防治提供借鉴。

Based on the analysis of hidden danger of fully mechanized mining working face spontaneous combustion in high location, the comprehensive measures for the spontaneous combustion prevention are put forward. The effects of goaf gas emission and high-positioned bore-hole for gas extraction to spontaneous combustion are fully considered. The spontaneous combustion prevention are control schemes are analyzed in four aspects such as normal coal mining, slower than normal coal mining, area near the coal caving site, period during dismantling of support. It can provide reference for prevention and control of spontaneous combustion in gas drainage working face with high location.
