The Mechanism of Influence of Roof Properties on Impact Energy Distribution

Abstract:

The properties of roof play an important role in the formation and occurrence of rock burst. FLAC 3D is used to simulate the process of excavation and collapse in face advance with difference roof properties based on the elastic theory and field data of “7.16 Accident of rock burst” at Chengshan coal mine. As a result, the energy distribution law on the monitoring plan under different roof properties is given with Fish function. According to the analysis above, hard roof is a crucial reason to cause the accident.
