"Unloading-slippage mechanism of rock burst occurred in longwall roadwa" by Jun Han, Luyu Cui et al.
Rock burst seriously threatens the safety and economy of coal mining industry. The causality mechanism research of rock burst is of great significance. The occurrence of roadway rock burst accounts for 86.8% of the total rock bursts. Based on the phenomena of rock burst occurred in roadway, this paper considered that hard roof and hard coal are the key geological characteristics of rock burst, and the sliding instability of rib coal mass is their specific failure attribute. Based on the elastic foundation theory, the upward deflection characteristics of the front and lateral roof of the workin...
