    On the survey basis, the productivity and unit operating cost of LHD used in some underground mines in China are generally reviewed. It has been pointed out by the author that the application of LHD has brought about great changes in underground mining techniques and made LHD ma-chines become one kind of major mucking equipments in several China's un-derground mines. Nevertheless, owing to the lower annual productivity per unit and its higher unit operating cost, a further widespread application of such machines...

    On the survey basis, the productivity and unit operating cost of LHD used in some underground mines in China are generally reviewed. It has been pointed out by the author that the application of LHD has brought about great changes in underground mining techniques and made LHD ma-chines become one kind of major mucking equipments in several China's un-derground mines. Nevertheless, owing to the lower annual productivity per unit and its higher unit operating cost, a further widespread application of such machines has been considerably restricted. thus, from the viewpoint of economic effectiveness, the auther has proposed that in developing under-ground mine equipments, some specific models of machines should not be uni-laterally stressed on, while some available improvements and developments of different types of loading and hauling machines are necessitated corres-pondantly with the practical conditions and certain technical level of the mines. In the end, some helpful approaches for improvements to the appli -cation of LHD in our mines are also suggested.

    作者在调查研究的基础上,论述了铲运机在我国地下矿山的生产能力和作业成本。指出,虽然铲运机的应用促进了我国地下矿山采矿工艺的变革,且在部分矿山已成为主要出矿设备之一。但因各种原因,它的实际台年生产能力仍相当低,作业成本也较高,从而使它在我国矿山的进一步推广应用受到了很大的限制。因此,从经济效益的观点出发,作者提出,在发展我国地下矿山机械设备中,不应片面强调某种机械模式,而应结合矿山的实际情况和技术水平,改进和发展不同形式的装运设备。最后,作者对我国矿山使用铲运机的状况,提出了改进措施。

    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.

    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。
