摘要:由于封堵不良钻孔形成的导水通道而造成煤矿突水事故时有发生,特别是奥陶系石灰岩含水层(简称“奥灰”)
钻孔隐性封孔不良,其形成的水害隐患更具有突发性、隐蔽性,对安全生产影响严重。以兴隆庄煤矿为例,通过
对三灰地层的一采区石门巷道新增出水点、出水水样呈奥灰水质特征以及奥灰、十下灰水位异常等水文地质异常现
象的分析研究,可以判断奥灰钻孔具有隐性漏水。主要原因是由于地质条件变化,在未下套管前的钻孔意外进入
奥灰富水区,从而导致高压、高流速水流向其他含水层排泄,使得水泥封孔效果不佳形成隐性导水通道。据此提
出井下钻孔化学注浆的防治方法,可对该类水害的防治有指导意义和借鉴价值。

Abstract:Some of the water inrush accidents in mining are caused by unfavorable blocking of boreholes;and
water inrush caused by unfavorable blocking of boreholes in aquifer of Ordovician limestone is the most harmful.
Taking Xinglongzhuang coal mine for example,the potential water leakage of the boreholes in aquifer is
introduced according to the hydrogeological data collected from the new water
