某建筑石料用灰岩矿高边坡稳定性分析

Stability Analysis of High Slope of Limestone Mine for Building Stone

以某建筑石料用灰岩矿开采形成的岩质高边坡为例,确定了采场边坡工程地质分区和优势软弱结构面,对研究区域的地震作用、爆破振动力参数进行了分析,采用定性、定量相结合的方法对矿山开采边坡进行了稳定性分析评价。结果表明,地震、爆破作用下,会降低边坡稳定安全系数。通过对结果的对比和解读,对开采边坡提出了监测建议,为同类岩质高边坡的开采设计提供借鉴。

Taking a high rock slope formed by the mining of a limestone mine for building stone as an example,the engineering geological zoning and dominant weak structural planes of the mining slope were determined.The seismic effects and blasting vibration parameters of the studied area were analyzed,and a combined qualitative and quantitative method was used to evaluate the stability of the mining slope.The results showed that under the influence of earthquake and blasting,the slope stability was affected.Through comparison and interpretation of the results,monitoring suggestions were proposed for the mining slope,providing a reference for the design of similar high rock slopes.
