摘要
针对矿井瓦斯基础参数缺乏,采掘部署不合理,预抽措施不合理等区域防突措施不完善的问题,对茶园煤矿瓦斯基础参数进行了测试。通过掌握回采工作面的瓦斯赋存规律,并加强地质构造带抽放钻孔的施工力度,合理布置采掘工作面,确定合理的瓦斯抽放预抽期,进行工作面消突效果预评价,确定检验孔的布置原则等工作,对区域防突措施进行了优化。
Aiming at the problems of lacking of mine gas basic parameters, mining deployment unreasonable, pre -pumping measures unreasonable and regional outburst prevention measures imperfect, basic parameters of coal mine gas in Chayuan coal mine were tested. By mastering the gas occurrence laws of mining face, strengthening construction efforts of drainage holes in geological structure, ration- ally arranging the mining face, determining reasonable pre - drainage period of gas drainage, carring out the pre - assessment of out- burst elimination effect in working face, determining the layout principles of test hole, this paper optimized the region outburst preven- tion measures.
