摘    要：本文对兰州有色冶金设计院提出的《宝山铜矿矿山开采二期工程可行性研究报告》的开采方法、地下采矿方法及矿山生产能力等问题进行全面的论证与分析,得出了如下不同的结论: 用无底柱分段崩落法作为确定开采方法的主要依据,确定全部采用地下开采法的结论值得进一步商榷。最好选用有底柱分段崩落法,有底板漏斗的空场法等多种有内在联系的采矿方法,以适应矿体变化大的特点。矿山生产能力以不超过1000吨/日为宜。

Abstract: In this paper, we shall discuss the research report on the feasibility mining engineering of Baoshan Copper Mine in the second phase of the project covering the mining method, underground mining method and mine production capacity suggested by the Lanzhou Designing Institution of Non- ferrous Metallurgy, and shall make an all-round demonstration and analy- sis. The different conclusions are suggested as follows, The conclusion that the sublevel caving method can be used as the major basis in determining the mining method, that is, determining the underground mining method in the second phase of the project, is open to question. For the purpose of being suited to the characteristic that the ore body changes greatly, it is better to selectively use sublevel caving (with floor pil1ar) and open stoping with drawing chute located in foot wall etc. with various internal relations. And it is better to limit the min- ing capacity to below 1000 ton/day.
