摘要
基于小西煤矿3107工作面在回采过程中,工作面上隅角频繁出现瓦斯超限、断电现象,严重制约着工作面安全高效回采,该矿在分析3107工作面主要瓦斯来源及上隅角瓦斯超限原因的基础上,提出了“大直径瓦斯钻孔抽采+裂隙钻孔瓦斯抽”综合治理技术,通过实际应用表明,综合瓦斯治理技术成功解决了上隅角瓦斯积聚超限的技术难题,保证了工作面安全高效回采。
Based on the main gas sources of 3107 working face and the gas overrun in the upper corner,the"large diameter gas drilling extraction+fissure drilling gas extraction"was given.Through practical application,it showed that the integrated gas management technology successfully solved the technical problem of gas accumulation overrun in the upper corner,which ensured the safe and efficient recovery of the working face.
