摘　　要：通过对程潮铁矿东区无底柱分段崩落法开采地压活动规律的调查 ,分析了采场进路失稳的影响因素和冒顶机理 ,对采场进路的受力状况和上盘岩体的渐进崩落过程进行了计算 ,为合理地控制地压提供了科学依据。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.
