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。
Based on the investigation of the underground pressure law of the subsoil caving in the east of Chengchao Iron Mine, the influencing factors of instability and the mechanism of roof fall are analyzed. Asymptotic collapse process was calculated, providing a scientific basis for the reasonable control of ground pressure.
