NUMERICAL ANALYSIS OF PANIC MINE ROCK BURST MECHANISM
Coal (rock) layer mechanical properties and in-situ stress are the main factors that influence rock burst occurrence. Bases on the practice of Panic mine production, it is found that the coal (rock) seam mechanics strength and stiffness parameters and the ratio between three principal stresses generated by tectonic stress and gravity are the key factors which influence rock burst in the coal mining process. This paper uses numerical analysis method to study the influence of the ratio of principal stress, pillar size, roof strength and stiffness on rock burst conditions.
