摘　　要：缓倾斜至倾斜中厚矿体回采普遍存在矿石运搬困难、采切比高、损失贫化大等缺点,特别是属于该类型矿体的低品位矿山,如何降低采矿成本、提高回采效率是其最重要的攻坚方向。通过优化采切工程布置,改进采矿装备,应用无轨设备等多个举措,比较成功地降低了采矿成本,提高了入选品位,取得了良好的经济效益,可为类似条件下的矿山开采提供经验和参考。In the mining of gently inclined to inclined medium thick ore body,there are many disadvantages,such as difficult ore haulage,large ratio of extraction-to-stope drift,large loss and dilution.Especially in the low-grade mine of this type of ore body,how to reduce the mining cost and improve the mining efficiency is the most important direction.Through the optimization of mining and cutting engineering layout,improvement of mining equipment,and application of trackless equipment,it has successfully reduced mining costs,increased the selection grade,and achieved good economic benefits,which can provide referenceand mining experience for similar conditions mine.
