| 摘 要： | 以北干沟金矿的地质条件和开采现状为条件，对倾斜薄金矿脉采场用混凝土假底柱结构或矿石底柱结构这两种结构形式进行了优化选择。优选条件是该矿段开采金的经济品位界限，计算的矿体金地质品位大干２．５２ｇ／ｔ时可选择假底柱结构。

| Abstract: | Based on the geologic condition and present mining·situation of Beigangou mine,the optimization of the form of stope sill structureto be used for the mining of inclined thin gold vein was discussed in this paper.Optimizatlon is the economic cut-off limit of the gold ore to be mined.The false(concrete)floor pillar structure can be selected when the calculated geological grade is above 2.52 g/t. |
