摘要
以镇城底矿井下水文钻孔出水为例,分析了出水事故的原因,并根据出水水压较大的情况,提出通过配重减压,在隔水层安置止水塞止水的治理方案,达到止水的目的。提出帷幕注浆的方法,封堵了导水的裂隙、构造等通道,改良隔水层性能,为今后9#煤开采创造安全水文地质条件。
Takes underground hydrographic drilling water in Zhengchengdi coal mine as an example, analyzes the cause of the water accident, and according to the condition the treatment scheme through counterweight reduced pressure, which effluent water pressure is larger, puts forward placed the sealing plug in water-resisting layer, achieves the purpose of sealing up. Puts forward the curtain grouting method, plug the channel of the water conduction fracture, structure and so on, improves the performance of conditions for future the No. 9 coal mining.
