摘要
针对同发东周窑矿沿空掘巷受采空区积水影响的现状,利用工作面实测标高对比确定积水范围及积水形态,计算出采空区积水量、积水面积及积水深度,分析采空区积水规律;并提出采空区积水“安全高度”理论,高于“安全高度”时,采用水仓施工钻孔放水法,可高效快捷超前疏放采空区积水,为采掘接替和矿井安全生产提供治理经验。
Based on the current situation of gob-side entry driving affected by goaf water in Tongfa Dongzhouyao colliery,by comparing the measured elevation of work face,determines the scope and form of water accumulation,calculates the water volume,water area and water depth,analyzes the law of water accumulation in goaf,and put forward the safe height theory of goaf water.When the elevation of roadway is higher than the"safe height",boreholes are drilled in the sump to drain the goaf water efficiently and quickly,that provides treatment experience for excavation replacement and construction safety and efficient.
