摘要
长田金矿矿石中等稳固,围岩稳定性极差,顶板不允许要较大面积的暴露,开采范围内矿体小而多,空间上多个矿体重叠,垂直间距在10m^50m不等,根据矿岩稳定性的特点,对倾角30度以下的矿体采用上向进路充填采矿法开采,该采矿方法对国内同类矿山开采具有较高的推广价值。
The ore of the Chang Tian gold mine is medium and stable,the stability of the surrounding rock is very poor,the roof is not allowed to be exposed to a large area,the ore body is small and many in the mining range,the space is overlapped by multiple ore bodies and the vertical spacing is 10m^50m.According to the characteristics of the rock stability,the updirection filling mining method is adopted for the ore body under the dip angle of 30 degrees.The mining method has high popularization value for similar mining in China.
