摘要
徐庄矿工作面局部有顶板破碎现象发生,伴随局部冒顶,直接顶频繁出现周期来压,造成煤壁片帮以及顶板大面积冒落,对井下安全生产造成了一定影响,通过对7191工作面进行高分子材料注浆加固,提高了煤岩体的整体强度,解决了冒顶的问题。
The phenomena of part roof collapse in Xu Zhuang coal mine was quite common. With the partial roof collapse, periodic pressure appeared in immediate roof, and caused the fall of coal wall and roof falling in large area. It threatened the security of coal mine. This paper describes the application of polymer grouting materials in 7191 working place of Xu Zhuang coal mine. The construction result not only increased the overall strength of coal-rock mass, but also solved the problem of roof collapse.
