Abstract:An overview of the investigations on coal bumps in China is presented from three aspects:mechanism,forecast and control. The key issues and the corresponding scientific achievements of investigations on coal bumps in recent years are reported. These issues involve the geological conditions related to coal bumps and the quantitative analysis method,the time-space distribution of mining-induced stress and energy in mining disturbed region,and the spatial structures of overlying strata and its mechanism of coal bump triggering. Several technical systems of monitoring and warning for coal bumps are introduced. These systems involve the integrated monitoring system of stress and seismic fields,the monitoring and detecting system of coal bumps,the ZOS distributed micro-seismic monitoring system,the wireless monitoring system of coal bumps and the electrical charge monitoring technique. Finally,some new techniques for controlling coal bumps and related application in mining groups of Datong and Yima are discussed. The control methods include the energy-absorption and anti-scour support,the anchor bolt with constant resistance and large deformation,and the regional prevention technical system based on stress control.
