煤矿底板奥灰水害防治分析

Analysis on the Prevention and Control of Ordovician Limestone Water Disaster in Coal Mine Floor

以煤矿底板奥灰水害防治为对象开展分析,结合具体工程实际,在分析作业面底板突水情况的基础上,对作业面注浆堵水作业开展全面总结,并对其应用效果做出探究。结果表明,通过注浆作业实现了对作业面奥灰水害问题的有效防治,提升了作业安全性,为矿井综合效益的增加提供了有力保障。

This paper analyzed the prevention and control of Ordovician limestone water disaster in coal mine floor.Combined with the actual project,based on the analysis of the water inrush from the floor of the working face,it comprehensively summarized the grouting and water blocking operation in the working face,and made a study of its application effect.The results show that the grouting operation can effectively prevent and control the water disaster of the working face,improve the safety of the operation,and provide a strong guarantee for the increase of the comprehensive benefits of the mine.
