摘要
露天采矿场边坡失稳作为露天开采矿山常见的一种地质灾害,对采矿工人的人身安全和矿山开采设施及财产造成了极大危害。本文通过对大宝山露天采场边坡相关影响因素的研究,从影响采场稳定性的地质因素、采空区综合分析,辅以赤平极射投影的方法,探讨了在复杂地质背景下露天采场边坡失稳地质灾害的预测及其综合治理对策。
As a common geologic hazard in open-pit mine,slope instability greatly endangers the safety of miners and causes serious damage to the mining equipment and properties.Through studying the related influencing factors of the side slopes in Dabaoshan open-pit mine,and combined with stereographic projection method,this paper comprehensively analyzed the geological factors and goaf areas which had impact on the stability of the open pit.The paper also discussed how to forecast the geologic hazard of slope instability of open pit under complex geological conditions and its control measures.
