摘要
通过对陕西省高瓦斯矿井的形成原因进行分析,指出从高瓦斯煤矿的地质现状和抽采条件出发,以地面羽状井抽采为主要手段,可有效减少矿井瓦斯含量,促进煤矿安全生产,大幅度降低陕西的煤矿瓦斯事故危害,具有长远的经济和社会效益,并选择大佛寺煤矿、下石节煤矿、象山煤矿开展瓦斯地质勘查和抽采工程,提出了不同的施工方案。
Based on the analysis of the formation of high -gas mines in Shaanxi, it is pointed out in the paper that from the geological and pumping conditions and by using pinnate horizontal multilateral well, the gas content should be cut down effectively and coalmine gas disaster should be avoided. Meanwhile, Dafeshi, Xishijie and Xiangshan coalmines are selected to carry out geological exploration and ground pumping and different plan and approaches are put forward.
