Abstract

Rockburst, coal bump, and mine earthquake are the most important dynamic disaster phenomena in deep mining. This paper summarizes the differences and connections between rockburst, coal bumps and mine earthquakes in terms of definition, mechanism, phenomenon, evaluation index, etc. The definition and evolution progress of the three disaster categories are summarized, as well as the monitoring, early warning, and prevention measures are also presented. Firstly, by combining theoretical research with specific technologies and engineering field cases, the main categories and failure mechanisms of rockburst, coal bumps and mine earthquakes are introduced. Then, the evaluation indexes of coal bump and mine earthquake are summarized, and a new evaluation index of rockburst is given. Finally, the characteristics of monitoring, early warning technologies and prevention methods of rockburst, coal bumps, and mine earthquakes are discussed in technology and application. At last, the future directions of rockburst, coal bump and mine earthquake are put forward.

深部开采中岩爆、煤凸和矿震的发生机理及预防技术

岩爆、煤突、矿震是深部开采中最重要的动力灾害现象。本文从定义、机理、现象、评价指标等方面总结了岩爆、煤突与矿震的区别与联系。总结了三类灾害的定义和演变过程，并提出了监测、预警和预防措施。首先，通过将理论研究与具体技术和工程现场案例相结合，介绍了岩爆、煤突和矿井地震的主要类别和破坏机理。然后，总结了煤崩和矿震的评价指标，并给出了新的岩爆评价指标。最后，从技术和应用两方面探讨了岩爆、煤块和矿震的监测特点、预警技术和预防方法。最后，提出了岩爆、煤凸起和矿震的未来发展方向。
