动压影响条件下水平大巷超前加固技术研究

Research of the Level Tunnel Leading Consolidation Technology with the Effect of Dynamical Pressure

针对漳村煤矿西下山主要巷道压力大、采用传统支护方式难以解决巷道支护在邻近工作面回采期间变形的问题,提出动压影响条件下超前加固技术,有效解决了受动压影响巷道变形问题,并带来可观的经济效益和社会效益。

In Xixiashan of Zhangcun Coal Mine, the main tunnels bear high pressure, and traditional supporting ways are hard to solve the problem that tunnel support on nearby stope becomes deformed during stoping. In view of this problem, the leading consolidation technology has been put forward and effectively solves the problem that the tunnel becomes deformed with the effect of dynamical pressure, and brings great economic results and social benefits.
