浅谈动压巷道的治理方法

Treatment Method of Dynamic Pressure Roadway

随着煤矿开采技术的成熟,开采强度、深度不断加大,国内矿井深度达800 m以上的矿井较为普遍,深度开采开掘的巷道受高应力影响,回采巷道存在不同程度的变形,巷道维护困难,返修率高。对受采动影响的巷道破坏进行原因分析,并提出应对措施。

With the maturity of coal mining technology, the mining intensity and depth are increasing, and the mine with a depth of more than 800m is more common. The roadway in deep mining is affected by high stress. The roadway has different deformation, the roadway maintenance is difficult and the rate of rework is high. In this paper, the reasons for roadway damage caused by mining arc analyzed, and the countermeasures are put forward.
