【Abstract】 Combining the plate theory of rock mechanics with in situ experiment,the paper make a research on the subsidence laws of false roof and influence factors of stability after the exposure of stope by top slicing stoping and filling in Wushan copper mine. Some conclusions of keeping the stability of false roof in stope are gained,supply some valuable references for the other mines.更多还原
