| Abstract: | For realized safety production in the mining of large mining deep, big dip- angle, down- inclined and slope adjust- ment, it＇ s needed to solve the problems of coal wall split, supports pith, collapse, slide and bite in the course of working face down - inclined mining, coal mining machine curve gear wheel bite belt conveyer, overturn and bore side, cluster of waste rock. In this paper, aim at the real mining problems, the key technology measure and specialized slope adjustment scheme were adopt- ed and carried out in Kongzhuang Mine. The conclusion indicated the special mining scheme can effectively resolve the key tech- nology problems in complex conditions. |
