摘　　要：露天开采的建筑用石料矿山多以岩质边坡为主,顺山坡开采形成的终了边坡稳定性受当地的自然环境条件、地质条件、斜坡结构类型等控制。以福建霞浦县二洋里建筑用石料矿山为例,应用极射赤平投影法对边坡稳定现状、发展趋势、破坏模式等进行定性稳定性分析评价,为同类型露天开采矿山岩质边坡的定性稳定性分析提供了实例借鉴。Most of the stone mines used in open pit mining for construction are rock slopes.The stability of the final slope formed by mining along the hillside is controlled by the local natural environment condition,geological condition and slope structure type.Taking Eryangli stone mine for construction in Xiapu County,Fujian as an example,the slope stability status,development trend and failure mode are analyzed and evaluated by the stereographic projection method,which provides an example for qualitative stability analysis of rock slope in the same type of open-pit mining.
