Research status and prospect of coal bumps prevention and control technology

Based on the latest data of coal bumps mine in China，the research status of coal bumps has been summarized from these aspects: catastrophic mechanism, monitoring and early warning, and control technology. This paper summarizes the catastrophic mechanism of coal bumps, and discusses the research status of coal bumps control mechanism from three aspects of coal rock properties, environmental stress and occurrence structure. There are many monitoring and early warning platforms and equipments, and the application status of six systems (self-seismic microseismic monitoring system, stress on-line monitoring system, joint monitoring and early warning system of vibration field-stress field,full-frequency wide-area vibration monitoring system, electromagnetic radiation monitoring instrument and charge monitoring system) which are widely used in the field is expounded. China has initially formed a technical system for control of shallow coal bumps disaster, and the development status of active support and control technology and equipment are expounded. It puts forward the following understandings for the study of coal bumps control in China: the multi-scale effect of catastrophic damage and the multi-scale transformation mechanism are the new breakthrough to reveal the catastrophic mechanism; the only way for the development of coal rock dynamic disasters control technology is to start from the three aspects of properties, environmental stress and structure control, and to combine high efficiency and intelligent control equipment; the integrated prevention and control of coal rock power disasters is an inevitable requirement for deep mining.
