【摘要】 煤炭资源开采中采场顶板水水害是威胁工作面安全生产的灾害之一。以兖州矿区东滩煤矿综放开采14310工作面在回采过程中的涌水情况为例,在分析地质和水文地质条件基础上,从构造控水机理出发,分析了工作面特殊构造条件下顶板砂岩含水层的赋存规律和涌水规律,实施了14310工作面安全回采的探、放水工程、泄水巷工程和完善排水系统等相关水害综合防治方法,最终实现了工作面的安全回采。更多还原

【Abstract】 Water hazard from roof is one of the hazards threatening the production of working face.This paper takes the water inflow conditions in 14310 fully mechanized and roof caving working face of Dongtan mine as example.On the basis of analysis of the geological and hydrogeological conditions,the water inflow of mine working face is forecasted according to the water-bearing mechanism of the structures.The engineering of water detection and drainage,drainage tunnel and drainage system are implemented for safe caving in the 14310 working face.And the mine safety has been realized in the working face finally.更多还原
