【摘要】 建设本质安全型矿井,高产高效绿色开采是当今矿山发展的方向,文章提出了矿井全封闭定点式通风的新思路:采用全封闭管路向井下定点通风地点供给空气。矿井除定点通风地点以外处于缺氧高浓度煤层气状态,而不具备火灾、爆炸条件,通风尾气排入采空区进行遗煤气化,进行煤与瓦斯同采的绿色开采,对密闭房平台采用数字化监控管理,实现矿井瓦斯治理与利用,改善井下环境,为建设本质安全型矿井打下基础。更多还原

【Abstract】 The construction intrinsically safe mine,high yield and high effective green mining is the mine development direction,this paper proposed the mine entire seal fixed point type well ventilated new mentality now,uses all seals up the pipeline to ventilate the place supplies air to the mine shaft fixed point.The mine ventilates the place besides the fixed point to be at the oxygen deficit high potency coalbed methane the condition,but does not have the fire,the detonation condition,ventilates the exhaust to disperse into picks the depletion region to carry on loses the gasification,carries on the coal and the gas with green mining which picks,uses the digitized monitoring management to the airtight room platform,the realization damp government and the use,the improvement mine shaft environment,builds the foundation for the construction intrinsically safe mine.更多还原
