摘要
甲玛铜多金属矿海拔4000~5407 m,该矿存在着大量采空区,为防止井下采掘活动出现冒顶、片帮及矿柱破裂等动力灾害,有必要对其进行地压监测。而在对这种高寒高海拔金属矿山进行地压监测的研究非常罕见。本文应用微震监测技术对该矿进行地压监测,首先介绍了甲玛矿地质条件和围岩情况,接着描述了甲玛矿微震监测系统的结构与监测点位置,然后对监测数据进行微震数据分析和应力分布情况分析,掌握高寒高海拔金属矿山地压活动时空演化规律。
Jiama Copper Mine,with an altitude of 4000-5407 m,have a large number of mined out areas.In order to prevent the dynamic disasters such as roof fall,spalling and pillar fracture,it is necessary to monitor the ground pressure.It is very rare to monitor the ground pressure in this kind of metal mine.In this paper,the microseismic monitoring technology is used to monitor the ground pressure of the mine.Firstly,the geological conditions and surrounding rock conditions of Jiama mine are introduced.Secondly,the structure of the microseismic monitoring system and the location of the monitoring points are described.Then,the microseismic data analysis and stress distribution analysis are carried out on the monitoring data to grasp the temporal and spatial evolution law of the ground pressure activities in the metal mines with high altitude and cold.
