基于微震监测技术的断层突水预警预测研究

三山岛金矿是山东黄金集团有限公司的主要矿山之一，目前已进入深部开采，开采深度已超过1000m。随着开采深度的增大，地质条件恶化，大量地下水涌出，断层突水问题严重影响井下安全生产。介绍了微震监测技术的基本原理，针对矿区特有的水文地质条件及生产情况，布置适合监测金矿生产安全的微震监测系统；基于对监测结果的系统分析，研究断层突水预警技术思路；对监测微震事件与水量监测结果进行对比、分析其内在的联系性，为通过微震对矿区存在的断层突水危险进行判别提供技术支持。通过研究实现了深部开采的突水监测和预警。

Prediction research of fault water bursting based on seismic monitoring technology

Sanshandao gold mine is one of main mines in Shandong Gold Group, which has entered deep mining stage and the mining depth will exceed one kilometer. With mining depth rising, problems caused by large quantity of increased ground water inflow seriously affect safe production. Micro-seismic monitoring system for monitoring the safe- ty of gold mine is installed according to local hydrogeology and production conditions ; based on the analysis of monito- ring results, technical ideas of fault water bursting prediction is studied ; comparison between micro-seismic events and water quantity monitoring are put to study its internal relation, which provide support for discriminating fault water bursting risk through micro-seismic. The monitoring and early warning of deep mining are achieved through the re- search.
