| 摘 要： | 应用卸压槽维护被跨采巷道,是采用人为卸压的方法改变巷道围岩应力场的分布规律,控制围岩变形,缓解矿山压力对巷道的影响。卸压槽的开挖时间、卸压槽间间距、卸压槽位置、卸压槽内的支护情况等,对减少矿山压力、对巷道的影响,均有密切关系。

| Abstract: | To use relaxed slot to maintain roadway passed by working face is to change the distribution of host rock stress around road-ways so as to control host rock deformation and reduce the influence of underground pressure on roadways. The reduction of the influence of undergound pressure has close relationship with the time of cutting slot, the distance between the positions of slots and the support condition in the slot, |
