Coalface Rock Burst Evaluation by Multifactor Coupling Method

In order to overcome the blindness of rock burst forecasts, multifactor coupling method is adopted to divide scientifically latent dangerous area which affected by mining and determine the level of rock burst danger. Typical rock burst is analyzed by the aid of microseismic monitoring location system, which demonstrates the scientificity and practicality of the method in the practice of coal mine. In this way, the safe development of working faces with severe rock burst can be done.
