摘　　要：在煤矿施工环境中存在大量的瓦斯,且不同煤层瓦斯含量也不同,即使是低瓦斯矿井中也存在高瓦斯区域。近几年经常在低瓦斯矿井中发生极其严重的瓦斯事故,这都是因为施工人员缺乏对低瓦斯矿井中的高瓦斯区域相关事故的处理经验,导致上隅角瓦斯含量超标,埋下安全隐患。对此煤矿企业在施工时应该建立井下临时瓦斯抽采系统和科学的瓦斯监测体系,并结合高位钻孔抽采等技术的使用对上隅角瓦斯问题进行有效治理,将瓦斯浓度降低并稳定在合理范围内。本文结合实际情况,对低瓦斯矿井高瓦斯区域上隅角瓦斯治理技术进行深入分析,并根据现有不足提出了具体的改良优化策略,以供参考。There is a large amount of gas in the construction environment of coal mines,and the gas content varies among different coal seams.Even in low gas mines,there are high gas areas.In recent years,extremely serious gas accidents have often occurred in low gas mines.This is because construction personnel lack experience in handling accidents related to high gas areas in low gas mines,resulting in excessive gas content in the upper corner and hidden safety hazards.Coal mining enterprises should establish a temporary underground gas extraction system and a scientific gas monitoring system during construction,and effectively manage the gas problem in the upper corner by combining the use of technologies such as high-level drilling and extraction,in order to reduce and stabilize the gas concentration within a reasonable range.This article conducts an in-depth analysis of the gas control technology in the upper corner of high gas areas in low gas mines based on actual situations,and proposes specific improvement and optimization strategies based on existing shortcomings for reference.
