极薄矿脉的改进型留矿法开采工艺研究

Study on Improved Shrinkage Mining Technology of Extremely Thin Vein

本文主要针对极薄矿脉回采过程中存在的损失贫化率高的问题,通过采取改进型留矿法,降低回采作业过程中的矿石损失贫化率,为极薄矿脉回采作业提供技术指导。

According to the problem of high loss and dilution rate in the process of extremely thin vein mining, the improved shrinkage method is adopted to reduce the ore loss and dilution rate in the process of mining operation, which can provide technical guidance for extremely thin vein mining operation.
