香炉山钨矿特大采空区地压微震监测技术应用研究

摘要

Ground pressure disasters have frequented Xianglushan Tungsten Mine in the past decade due to its complex shape and large size vacant area.A 48-channel digital-based microseismic monitoring system was installed to ensure safety of mining. This paper introduces the components of the multi -channel microseismic monitoring system and advantages. Early warning of ground pressure, positioning of stress concentration, guiding designing of mining, assessing activeness of ground pressure in total mine and monitoring ore stealing are specially focused. Results and analysis showed that the microseismic monitoring technology has produced positive effects in Xianglushan Tungsten Mine.%香炉山钨矿东区形成了形状复杂、体积巨大的采空区,地压灾害问题突出.为了确保矿山生产安全,该矿成功地建立了国内属先进的48通道全数字型微震监测系统.本文简要介绍了多通道微震监测系统的组成及技术特点,重点分析了微震监测技术在地压灾害预警、应力集中危险区域圈定、指导采矿设计、矿区整体地压活跃程度评价与监控民采盗矿等方面的成功应用实例,证明了微震监测技术已经成为该矿山残采区地压监测、生产安全预警的基本手段.
