Water prevention and control method for coal mining working face of coal mine
The invention discloses a water control method for a coal mine coal face. The water control method comprises the following steps that S01, a haulage roadway, an air return roadway and an open-off cut roadway of a stope face are excavated, and working face equipment is arranged; s02, freezing holes are drilled in the water source boundary of the top plate and the bottom plate along a coal face haulage roadway or an air return roadway; s03, freezing pipelines and freezing equipment are arranged; and S04, starting the freezing equipment to form a top plate freezing circle layer. The problems that in the prior art, controllability is poor, or drainage is difficult, and the operation period is long are solved.
本发明公开了一种煤矿采煤工作面防治水方法,包括以下步骤:S01、开掘回采工作面运输巷道、回风巷道及切眼巷道并布置好工作面设备;S02、沿着采煤工作面运输巷道或回风巷道向顶底板水源边界钻冻结孔;S03、布置冻结管路和冻结设备;S04、启动冻结设备形成顶板冻结圈层。以解决现有技术存在要么可控性较差,要么存在排水困难和作业周期长的问题。
