摘要
以山西和顺矿区天池煤矿首采101综放面为研究对象,结合矿井的地质条件提出一进二回的E形通风和顶板走向高抽巷抽采的瓦斯综合治理技术,但在工作面推进的过程中瓦斯超限时有发生,后改E形通风为二进一回的偏Y形通风。
101first fully mechanized top coal caving face of Tianchi mine in Heshun mining area of shanxi was researched, Based on the geological conditions of 101 first fully mechanized top coal caving face, the comprehensive gas control technology of one intakes and two ruturn of E ventilate system and the gas drainage of high pumping of trend in the roof were put forward to control gas in 101 first fully mechanized top coal caving face, but the gas accumulation was often occurred when advancing process of working face, one intakes and two ruturn of E ventilate system was replaced by two intakes and one ruturn of partial Y type ventilation.
