不良地质作用对金属矿山边坡稳定性影响及防治措施

Impact of Adverse Geological Process on Metal Mine Slope Stability and Precautions

随着金属资源的需求急剧增加,大型露天矿山开采范围逐渐扩大,不良地质作用对其边坡稳定性的影响日益严重,极大增加了矿区出现地质灾害的可能性,制约了矿山的安全高效开采。基于此,本文针对影响边坡稳定性的不良地质作用进行深入剖析,分别就断层活化、地震活动、复杂采空区等不良地质作用对边坡稳定性影响的关键因素进行综合分析。根据得到的影响因素提出了削坡压脚、加强锚固等措施进行针对性防治,为相似地质条件矿山提供有效解决方案,为矿山企业安全高效生产提供可靠保障。

With a surge in the demand of metal resources,the exploitation range of large-scale open-pit mines gradually expands and the impact on their slope stability by adverse geological process is increasingly severe,which greatly increases the possibility of geological hazards in the mining area and restricts safe and efficient mining.In light of this,this paper conducts an in-depth analysis of adverse geological process that influences slope stability.Comprehensive analysis is carried out on key factors of adverse geological process that affect slope stability,including fault activation,earthquake and complex mined-out area.Based on these obtained factors,targeted precautions are put forward,including slope cutting,foot backfilling and anchorage reinforcing,which can provide effective solutions and a reliable guarantee of safe and efficient production for mines with similar geological conditions.
