【摘要】 为了证明基于声发射(AE)技术的微震监测系统在指导矿山救援救灾实际应用中的可行性和必要性,通过对井下现场原位模拟测试:敲击试验,验证该监测系统在矿山应急救援中可以发挥其准确的时间、空间定位作用。结果表明:微震监测系统是一套行之有效的利用岩体受力变形和破坏后本身发射出的弹性波来进行监测工程岩体稳定性的技术,在搜救定位被困井下人员的过程中,尤其能够显示出系统的优越性。这种应用探索具有非常重要的理论价值和现实意义。更多还原

【Abstract】 In order to investigate the feasibility for a monitor system based on acoustic emission(AE)to guide mine rescue operations,an experiment called knocking test is conducted in underground tunnels.The monitoring system can provide a powerful alternative and effective guide for mine rescue operations.The test shows that the monitoring system can accurately detect and distinguish the sound wave induced by knock.Using the sound waves emitted from rock deformation and damage,the monitoring system can monitor rock stability.In particular,its temporal and spatial localizer is of significance for searching and locating personnel trapped underground.This study is very useful both in theoretical and practical aspects.更多还原
