摘要
针对快速、安全探放5205采空区老空水,消除采空区水害对162801工作面巷道掘进和回采的威胁这一问题,冀中能源峰峰集团新三矿利用采空区下部巷道,选择合适的地点施工探放采空区积水钻孔,放水量达13 245 m^3,基本疏放全部掘进巷道上部采空区积水,消除了上部采空区积水对下部162801工作面掘进及回采的水患威胁,保证了162801工作面的正常掘进与回采,实现了安全生产。
Based on the gob water in 5205 mined-out area, the drilling for surveying water was worked in the right place by using the lower roadway in the goaf, water flowage was up to 13245 m. The goaf water in the upper part of drivage roadway was released basically. The threat from the upper part goaf water to the lower 162801 face was eliminated. The safe construction was assured when the coal seam was mined in 162801 face. Finally, the safe production was achievedn.
