摘要
根据金厂峪金矿顶板不稳定的缓倾斜薄至中厚难采矿体的赋存条件 ,采用块体理论及数值模拟计算分析顶板的稳定性 ,提出了分两层逆向和顺向推进的房柱采矿法 。
In accordance with the occurrence conditions of the gently inclined thin and medium thick hard to mine ore body with unstable roof in Jinchangyu Gold Mine,the stability of roof is studied by means of block theory and numerical evaluation.The pillar and room mining method on upgoing and downgoing with two layers is presented,which is reference for the resource development and utilization of similar mines in the home and aborad.
