摘要
针对吉宁矿属于高瓦斯矿井以及2104综采工作面的回采煤层瓦斯含量实际情况,进行了本煤层钻孔边采边抽、迈步式掘进预抽采、采场上方裂隙钻孔抽采、工作面顺槽上隅角插管抽放等综合方法治理瓦斯,根据抽采瓦斯量和风排瓦斯量统计结果,判断该工作面瓦斯抽放效果达标,消除了瓦斯突出与超限带来的安全隐患,满足安全回采要求。
According to the actual situation of gas content in the coal seam of Ji-ning Mine which belongs to high gas mine and 2104 fully mechanized coal mining face,the mining side of the coal seam is extracted,the pre-extraction of the step-by-step excavation,the drilling of the fracture above the stope,and the work.According to the statistics of the amount of gas extracted and the amount of gas discharged from the gas,the gas drainage effect of the working face is judged to meet the standard,eliminating the safety hazard caused by gas outburst and over-limit,and meets the safety recovery requirements.
