中峪煤矿掘进工作面大面积分散出水治理技术的实践

Practice of Large Area Scattered Water Treatment Technology in Zhongyu Coal Mine Driving Face

对沁安煤电公司中峪煤矿12041工作面的突水事故原因进行了分析,基于工作面大面积分散出水的情况,制定了地面打钻注浆方案进行突水治理。实践效果表明:本次突水治理技术方案堵水效果较好,堵水率达100%,有效地解除了全矿井的水害威胁。

This paper analyzes the cause of water inrush accident in 12041 working face of Zhongyu Coal Mine of Qin'an Coal and Power Company.Based on the situation of large area of scattered water in the working face,a ground drilling grouting scheme is developed for water inrush control.The practical results show that the water blocking effect of the water inrush control technology is good,and the water blocking rate reaches 100%,which effectively relieves the water hazard threat of the whole mine.
