摘要
针对倾斜破碎薄矿脉的地质条件，通过改进、优化普通留矿全面法的结构、参数和回采工艺，使矿石损失率和贫化率分别降至8％和12％，采场生产能力达到55t／d，取得了良好的经济效益和社会效益．
The layout,parameters and stoping process of shrinkage method is improved and optimized to suit the geological conditions of fractured,thin and dipping ore veins. The improved method can lower ore losses and dilution to 8% and 12K,respectively,and the stoping production rate can reach 55t/d. The improvement results in high economic and social benefits.
