| 摘 要： | 微地震事件与煤矿井下的岩体破裂情况密切相关，而岩体破裂与采矿活动又有直接关系。对微地震监测可以发现岩体活动剧烈的区域，以合理指导开采，预防井下因采矿活动引起的冒顶，垮落等灾害的发生。研制了井下微地震监测的仪器设备进行监测，根据初至波时间差方法进行了微地震事件的定位，并在此基础上进行安全状况做出合理的判断。基于此，该技术未来有很大的推广价值。 |
| 关 键 词： | 采矿工程；微地震；安全监测；时差定位；安全判据 |

| Abstract： | Micro seismic(MS) events are closely related to underground rock mass crack, which has a direct relationship with the mining activities. With MS monitoring, the active area in rock mass can be found so as to instruct the mining work and to prevent disasters such as rock fall, collapse and so on. A set of monitoring equipment is developed to monitor MS activities and to locate the MS event by time-delay method, on the basis of which the safety condition is worked out. This method can provide a more rational judgment on the safety status of rock mass. Therefore, the MS monitoring technique is of great value in future. |
| Key words： | mining engineering; micro seismic; safety monitoring; time-delay location; safety criterion |
