采矿方法要因地制宜，转变采矿方法标准化思维定势是前提。针对紫木凼金矿局部矿段倾角变陡、厚度变厚的状况，开展了沿倾向中深孔落矿分层采矿法试验研究。详细介绍了试验矿块结构参数及回采工艺过程。应用取得了较好的技术经济效果。
Mining methods should improvise and stereotyped thinking of mining methods should be overcome in the first place.In light of local steepening and thickening of ore sections in Zimudang Gold Mine,the paper carried out experimental research on medium-long hole caving along the inclination and cutting mining method.The structural pa-rameters and the stoping of tested ore blocks are introduced in full.Its application reached satisfactory technical and e-conomic results.
