摘要
通过分析冶坪煤矿的充水水源及充水通道特征,提出了相应的防治水措施,通过瞬变电磁技术对注浆前后工作面底板岩层富水性进行实际探测,对比分析的结果表明注浆后底板岩层富水性得到降低,注浆加固效果明显,工作面注浆加固可减弱回采工作面底板破坏发育速率及破坏范围,对降低底板突水危险有着明显的正向作用。
By analyzing the characteristics of the water-filled water source and the channel in Yeping Coal Mine,corresponding water prevention measures are put forward.The water richness of the floor of the working face before and after grouting is actually detected by the transient electromagnetic technology.The results of the comparative analysis show that the grouting injection reinforcement effect is obvious with the water richness of the floor reduced,and the damaged rate and range oin the floor of the working face also reduced,it has an obvious positive effect on reducing the risk of water inrush from the floor.
