淮南矿区高瓦斯煤层群深井开采设计创新

近几年开发建设的矿井,由于不断加大设计创新力度,采取分区开拓、分区通风、煤与瓦斯共采等先进科学的设计理论,从而使建井工期、达产工期大为缩短,工作面单产水平大幅提升,安全生产状况大为改观,形成了一套适合淮南矿区复杂地质条件下的快速建井及高产高效核心技术体系,取得了明显效果,从而为淮南矿区复杂地质条件下深部高瓦斯煤层群安全开采提供了必要的技术储备和借鉴经验.

Innovation on deep mining design of high gassy seam group in Huainan Nining Area

Due to the innovation of the design continuously increased,the mines were recently developed and constructed with the advanced scientific design theory,including the sectional development,sectional ventilation,coal and gas jointly mining.Thus the mine construction period and mine in production period were high reduced,the face production level was highly increased and the mine safety production status was highly improved.A set of a rapid mine construction and high production high efficient technical system ...
