最近,晋煤集团寺河矿矿井瓦斯抽采量大幅跃升,突破210万立方米,实现了10万立方米的增量,创全国单井瓦斯日抽采量的最高纪录。作为全国首座高瓦斯突出条件下的千万吨级大型现代化矿井,寺河矿始终坚持“瓦斯可治、突出可防”的理念,在“三级瓦斯治理”模式基础上,大规模投用普通钻机和定向钻机,抽放系统不断扩容升级,千米钻孔进尺占比从23%提升至45%,浓度由60%提 Recently, Shanxi Coal Mine Group Sihe mine gas drainage increased dramatically, breaking 2.1 million cubic meters, to achieve an increase of 100000 cubic meters, creating a single well gas daily pumping extraction record. As the first large-scale 10-million-ton well in the country’s first high-gas-outburst condition, Sihe Mine has always insisted on the concept of “gas can be cured and can be prevented”. Based on the “three-stage gas treatment” model, Large-scale investment with ordinary drilling rigs and directional drilling rigs, drainage systems continue to expand and upgrade, the proportion of kilometers drilling footage from 23% to 45%, the concentration from 60%
