Mechanism and monitoring and early warning technology of rock burst in coal mine

Based on a massive amount of published literature and the long-term practice of our research group in the field of prevention and control of the rock burst, the research progresses, and shortcomings in understanding the phenomenon of the rock burst have been comprehensively studied. The study was conducted to focus on the occurring mechanism, monitoring and early warning technology. The results show that the prevention and control of the rock burst have made significant progress. However, with the increasing mining depth, several unresolved concerns remain challenging. From the analysis of in-depth research, it is inferred that the rock burst related disasters include three main problems: The induced factors are complicated, and the mechanism is still unclear. The accuracy of monitoring equipment and the multi-source stereo monitoring technology is insufficient. The monitoring and warning standards of the rock burst need to be further clarified and improved. Combined with the Internet of Things(IoT), cloud computing and big data, etc., the study trend of the rock burst can be expected. Furthermore, the mechanism of multi-phase and multi-field coupling induced by the rock burst in large scale needs further exploration. The multi-system and multi-parameter integrated monitoring and early warning system and remote monitoring cloud platform for rock burst should be researched and developed. The high-reliability sensing technology equipment and perfect monitoring and early warning standards are considered as the direction of development for the rock burst in the future. This research will help experts and technicians to adopt effective measures for controlling the rock burst disasters.
