摘要 针对淮南矿区煤炭资源安全开采受煤与瓦斯突出、突水等典型动力灾害威胁严重的问题,基于煤岩微破裂是开采扰动下动力灾害发生的共性前兆信息的学术思想,系统总结了微震监测技术在淮南矿区覆岩采动裂隙演化、地质异常活化和A组煤底板破坏方面的应用。从开采应力扰动诱导煤岩裂化及微震活动入手,介绍了基于微震监测的煤矿水害风险预警与防控系统。分析认为,提高震源定位精度、实现微震监测数据智能分析、强化动态复杂多场微震信息挖掘分析与融合处理等技术研发对提升微震监测可靠性的作用巨大。 In view of the serious threat of coal and gas outburst,water inrush and other typical dynamic disasters to the safe mining of coal resources in Huainan mining area,based on the academic idea that coal-rock micro fracture is the common precursor information of dynamic disasters under mining disturbance,the application of microseismic monitoring technology in the evolution of overlying rock fractures,geological anomaly activation and coal floor failure in Huainan mining area is systematically summarized.Based on the analysis of coal-rock cracking and microseismic activities induced by mining stress disturbance,the early warning and control system of coal mine water disaster risk based on microseismic monitoring is introduced.The analysis shows that improving the accuracy of source location,realizing the intelligent analysis of microseismic monitoring data,and strengthening the mining and fusion processing of dynamic microseismic information play an important role in improving the reliability of microseismic monitoring.
