摘要
针对阿希金矿的开采技术条件,选用分段凿岩阶段空场嗣后充填采矿法开采,该采矿方法的工业应用效果较为理想,取得了较好的经济技术指标,技改前损失贫化达到25%,技改后,贫化率降为10%,损失率降为13%。
Aiming at the mining technical conditions of Axi Gold Mine,the open stope filling mining method at the stage of sublevel rock drilling is selected.The industrial application effect of this mining method is ideal,and better economic and technical indicators are obtained.The loss and dilution rate reaches to 25% after the technical transformation,the dilution rate decreases to 10% and the loss rate decreases to 13%.
