我国冲击地压发生机理、监测预警及防治现状与展望

Research status and prospect of rock burst in coal mines in China: mechanism, monitoring, early warning and prevention

  • 摘要: 随着煤炭资源开采深度增加与规模扩大,冲击地压已成为制约煤矿安全生产的重大动力灾害。系统综述了我国冲击地压在机理认知、监测预警及防治技术领域的研究进展。基于全国 150 余座冲击地压矿井的分布特征与典型案例,现有研究已揭示地质构造、采动应力、煤岩体属性及多场环境的多因素耦合致灾机理。在监测技术方面,现有成果通过对比微震、地音、电磁辐射等单一技术在深浅部开采中的效能差异,构建了“微震−应力−电磁”多参量融合预警平台,推动深部预警准确率得到提升。防治技术领域已形成“采矿优化设计−卸压减冲−防冲吸能支护”的协同体系,通过从源头规避风险、主动释放能量到被动缓冲防护的全流程管控,实现冲击地压“预防−治理−防护”的闭环防控。在门克庆煤矿等典型矿区的工程实践中,该体系已显现显著效果,使微震事件能级、能量及频次大幅降低。未来研究需进一步攻克人工智能驱动的多源数据融合、复杂地质条件下的主动防控等技术瓶颈,推动构建 “智慧防冲” 体系,为煤炭工业安全高效发展提供支撑。

     

    Abstract: With the increase in mining depth and scale of coal resources, rock burst has become a major dynamic disaster restricting the safe production of coal mines. This paper systematically reviews the research progress of rock burst in China in the fields of mechanism cognition, monitoring and early warning, and prevention and control technologies. Based on the distribution characteristics and typical cases of more than 150 rock burst mines in China, existing studies have revealed the multi − factor coupling disaster − causing mechanism of geological structures, mining − induced stress, coal and rock mass properties and multi − field environment. In terms of monitoring technology, existing achievements have constructed a "microseism − stress − electromagnetism" multi − parameter fusion early warning platform by comparing the efficiency differences of single technologies such as microseism, ground sound and electromagnetic radiation in shallow and deep mining, which has promoted the improvement of deep early warning accuracy. In the field of prevention and control technologies, a collaborative system of "mining optimization design − pressure relief and impact reduction − impact − resistant energy − absorbing support" has been formed. Through the whole − process management and control from avoiding risks at the source, actively releasing energy to passive buffer protection, the closed − loop prevention and control of rock burst "prevention − treatment − protection" is realized. In the engineering practice of typical mining areas such as Menkeqing Coal Mine, this system has shown significant effects, greatly reducing the energy level, energy and frequency of microseismic events. Future research needs to further overcome technical bottlenecks such as artificial intelligence − driven multi − source data fusion and active prevention and control under complex geological conditions, promote the construction of an "intelligent rock burst prevention" system, and provide support for the safe and efficient development of the coal industry.
