| Abstract: | By means of an investigation into the law of ground pressure activities induced by sublevel caving mining in the east section of Chengchao Iron Mine.This paper analyzed the factors affecting the stability of drift and the roof failure mechanism of stope and computed the load state of drift and the gradual caving process of hangingwall rock mass of stope so as to provide a scientific basis for the proper control of ground pressure. |
