Abstract: There are many coal mine “island”stopes left after the mining in China. The mining difficulties are increased in these mines because of the large number of abandoned roadways in the“ island” stopes. The two or three face, even all around goafs make the mine pressure reveal very prominent and the harm of rock-burst increased significantly. The old lanes and faults make the “island” stope mining more difficult than other stopes. Impact risks of Yangcun coal mine 315 coal face are analyzed from the aspects of geological condition and mining influence, which faces the factors of three face worked-out, dense old lanes and cross faults.
Key words: island mining; old roadway group; impact risk
