Abstract:
In order to enhance the ability of handling rock burst accidents in China, 4 examples happened from 2011 to 2013 were used to analyze the features and reasons of rock burst accident, and we also rethought the problems our accidents assistance facing now. Studies show that rock burst accidents often happened in the night and at advancing roadway where the coal is relatively deep in the underground and the geological conditions are complicated, and the accidents could cause workers badly injured and property greatly lost. Bursting tendency of coal and rock is the essential factor that causes the occurrence of rock burst, and complicated geological conditions would accelerate the disaster. Lack of protecting measures and supervisions are the important reasons which are responsible for the death of workers. In case of rock burst developing into a fatal disaster, it is suggested that the accident report process should be simplified, the global supervision system and emergency refuge system should be built. Meanwhile, workers should have the safety consciousness and the ability of rescue themselves to increase their survival rate.
