锚注支护技术在北山矿中部车场支护中的应用

The application of Bolt-grouting Supporting Technology in the middle section supporting of Beishan Colliery

分析龙岩市北山矿+410水平大巷中部车场受复杂地质构造影响,引起巷道两侧墙体及顶拱开裂,巷道变形破坏严重难以支护的原因;采用锚注支护方案较好解决了破碎围岩巷道支护的难题,为煤矿类似巷道围岩控制提供了适宜的方法和途径,具有一定推广应用价值。

Analyzing the effect of the middle section in 410 level tunnel Longyan Beishan Colliery by complex geological structure,it cause Roadway on both sides of the wall and cracking crown,and the reason why the support is difficult,which is due to the serious deformation.Bolt-grouting Supporting program is proposed,which solves the problem of the roadway support around broken wall rock,and this is a appropriate idea and method for colliery control such as the protection of the wall rock in a roadway.It is worth to popularize it.
