NUMERICAL SIMULATION OF COAL SEAM BURSTING HAZARD UNDER THE CONDITIONS OF THREE-HARD

摘要：

The rockburst mechanism of three-hard coal seam was analyzed, and stress variations of coalbed were researched using the numerical simulation method. After the analysis of the mechanics property in simulation and the intensity curve of coal mass, the evaluation method was achieved. The distribution and evolution law of coal seam bursting hazard were studied with this method.
