项目摘要

During the term from the fiscal year of 2005 till 2007, we have organized a group constituted by academic professions and supported by mining engineers and studied on "the applicability of the compact mining system in Mongolia and Central Asia".After the disintegration of the Soviet Union, Mongolia and the Central Asian countries introduced privatization and foreign investment in order to accelerate economic growth. While a couple of large scaled mines having developed, medium to small scaled deposits, especially compact ones, are left undeveloped. The developing countries are usually suffering from the scarcity of infrastructures and capital accumulations; even though the size of development of a compact mine is small, but the social and economic impact of the compact mine could be large and in some cases may lead to develop a larger deposit around the compact deposit.The scale merit of mining operation is broadly recognized in the sector of mineral industries. The larger the scale of … More operation, the more profit must be recoverable from a massive mineral deposit with lower grade. Against the conventional recognition, the compact mining system may make an appeal the advantage of small scaled mining, i. e., the flexibility of small operations may reduce a variety of risks. On the other hand, large mine developments and operations accompanying huge investments may be more vulnerable to risks in developing countries because of lack of social capitals and infrastructure.The success of the compact mining system can be endorsed by the Japanese mining engineering cultivated in and know-how having been stored by her medium to small scaled mining. In addition, mechanization, automation, information technologies should be incorporated in the compact mining system, which is characterized by a compact and consistent system from exploration to production with preference development of higher grade ore body and environment concerned development.The following are the key technologies for the compact mining system studied in the applicability of the system in Mongolia and Central Asia.・Narrow Vein Mining・Paste Backfilling Technology・Highwall Mining System・Mobile Mineral Processing System・Mine Project Evaluation by Real Option Analysis Less

在2005 - 2007会计年度，我们组织了一个由学术专业人员组成、采矿工程师支持的小组，对“紧凑采矿系统在蒙古和中亚地区的适用性”进行了研究。苏联解体后，蒙古和中亚国家为了加速经济增长，实行了私有化和外国投资。虽然有几个大型矿山已开发，但中小型矿床，特别是致密矿床尚未开发。发展中国家通常缺乏基础设施和资本积累；尽管紧凑矿山的开发规模很小，但紧凑矿山的社会和经济影响可能很大，在某些情况下可能导致在紧凑矿床周围开发更大的矿床。采矿作业的规模效益在矿业部门得到广泛认可。规模越大，作业越多，从品位较低的大型矿床中获得的利润就越大。与传统认识不同，紧凑采矿系统可能会吸引小规模采矿的优势，即小型作业的灵活性可以减少各种风险。另一方面，在发展中国家，由于缺乏社会资本和基础设施，伴随着巨额投资的大型矿山开发和业务可能更容易受到风险的影响。紧凑采矿系统的成功可以得到日本在中小型采矿中培养和储存的采矿工程技术的认可。紧凑采矿系统应结合机械化、自动化、信息技术，其特点是从勘探到生产的系统紧凑一致，优先开发高品位矿体和有关环境的开发。以下是紧凑型采矿系统在蒙古和中亚地区适用性研究的关键技术。·窄脉采矿·膏体充填技术·高壁采矿系统·移动选矿系统·实物期权分析的矿山项目评价
