摘 要:针对新大地煤矿大断面动压巷道的支护困难问题,通过采用高预应力锚杆锚索支护技术,有效控制了顶帮的围岩结构,实现了巷道顶板的稳定和安全,解决了顶板下沉、两帮破坏、巷道状况恶化等难题,为掘进工作面的高效掘进提供了条件,为巷道顶板支护设计提供了参考依据。The main points are as follows: in order to solve the support problem of large section dynamic pressure roadway, the surrounding rock structure of roof can be effectively controlled by using high prestress anchor cable support technology, and the roof of roadway can be stabilized and safe, and the roof sinking and two side failure can be solved. The difficult problems such as the deterioration of roadway condition provide the conditions for the efficient excavation of tunneling face and provide the reference basis for the design of roadway roof support.
