中文摘要：露天矿高边坡的稳定性影响到矿山施工和居民的生命财产安全,是矿山开采的关键问题之一。本文以温州露天矿开采边坡为背景,综合分析了高边坡周围的地形地质条件,对边坡进行了表面位移、竖向位移和深层水平位移监测,探究了露天矿高边坡的稳定性问题,并对其分析原因。监测结果表明,该矿山边坡西南方向位移变化较大,出现局部滑坡的概率较大,应加强防护;而爆破是影响边坡变形的直接因素,爆破次数与边坡变形位移量趋势基本一致。目前边坡累计位移量未达到警戒值,边坡整体处于稳定状态。通过对监测数据分析而知的边坡位移变形的原因和趋势,可为类似沿海露天矿高边坡稳定性分析提供借鉴和参考。

外文摘要：The stability of the high slope of the open-pit mine affects the mine construction and the life and property safety of residents,It is one of the key issues in mining.this paper takes Wenzhou open-pit mining slope as the background,comprehensively analyzes the terrain and geological conditions around the high slope,monitors the surface displacement,vertical displacement and deep horizontal displacement of the slope,and explores the stability of the high slope of the open-pit mine and analyze the reasons.The monitoring results show that the displacement of the mine slope changes greatly in the southwest direction,and the probability of local landslides is higher.Protection should be strengthened;while blasting is a direct factor affecting the slope deformation,and the number of blasting is basically the same as the slope deformation displacement trend.At present,the cumulative displacement of the slope has not reached the warning value,and the slope as a whole is in a stable state.The reasons and trends of slope displacement and deformation known through the analysis of monitoring data can provide reference and reference for the stability analysis of high slopes in similar coastal open-pit mines.
