冲击矿压的微震预测预报技术及工程应用
|
摘要
介绍了微震监测系统的基本原理和监测技术,并与传统的钻探法、近距离监测手段作了对比,指出了微震监测技术具有静态、实时和大范围监测的技术优势。对微震监测的监测结果作综合统计分析,参考矿井冲击矿压的历史统计资料,是冲击矿压冲击倾向性的基本技术手段;工程实践表明,用综合指标预测冲击矿压是可行、可靠的。随着各矿井采深的加大,微震监测技术将成为深部开采地质灾害预测预报的重要监测手段。
This paper introduced basic principles and technology of micro-seismic monitoring system.Compared with traditional drilling method and monitoring within close range,micro-seismic monitoring technology was static,real-time and could monitor from far distance.History data of mine rock-burst considered,monitoring data by comprehensive statistic might be as basic technical mean for rock-burst liability.Practice showed that comprehensive indices for rock-burst forecast were feasible and reliable.With mining depth increasing,micro-seismic monitoring technology would be important monitoring method for geological disaster forecast in deep mining.
