Knowledge of sub level caving method to control underground impact pressure
Based on the practical theory of ground pressure, the characterisitcs of roof coal movement and the distribution law of abutment pressure are nainly analyzed. The distribution law of inner stress field and its effect on controlling underground impact pressure are discussed, when sub-level caving method is introduced.
