摘要
通过研究矿区地层岩性、厚度和分布规律,划分岩(土)体工程地质岩组,查明对矿床开采不利的软弱岩组的性质、产状与分布,确定矿床工程地质条件,预测评价露天开采矿床开采边坡稳定性,以广东省恩平市某钼矿为例,通过矿区钻孔工程地质编录、岩(土)体力学实验等方法,确定矿区工程地质条件为中等,确定开采边坡稳定角不大于43°。
By studying the lithology,thickness and distribution,classifying the rock(soil)engineering geological rock group,we have identified the property,occurrence and distribution of the weak rock group which is unfavorable to the mining of the ore deposits,determined the engineering geological conditions,and predicted the slope stability of open-pit mining. Illustrated by the example of a molybdenum mine in Enping city,Guangdong province. By means of drilling engineering geological logging and rock(soil)body mechanics experiment,the engineering geological condition of mining area is determined to be medium,and the stability angle of mining slope is not more than 43 degrees.
