【摘要】：近年来国际金价的变动,以及金矿资源开采难度的不断加大,使得金矿生产企业面临着前所未有的困难。2004年2月云南省商品拍卖中心有限公司对原镇沅金矿的固定资产(不含矿权)进行了拍卖。中国黄金集团以4700万元竞拍成功,由中国黄金集团科技公司控股的云南黄金有限责任公司正式接管。镇沅金矿行政区划隶属于云南省镇沅彝族、哈尼族、拉祜族自治县和平乡,矿田南东段部分属玉溪地区新平县建新乡。本论文以案头文献综述为出发点,归纳分析了目前国内外金矿田开采的主要方式与方法,以及不同学者专家对金矿田开采成本控制的相关建议和对此;在此基础上,分析了镇沅金矿田的自然和矿产储备条件,从厂址选择、设备购买、人员投入等几个方面对镇沅金矿田的建设成本进行了研究,最后从制度保障、组织保障等角度提出了金矿田开发成本控制的保障措施。随着国际金价的进一步下滑,国内金矿资源的急剧下降,金矿田开采成本不断上升,对国内金矿田开发企业的生存与发展面临着重大的挑战。本论文的研究将有力地带动我国难处理金矿资源的开发利用,对促进黄金工业健康、稳定、可持续发展具有重要意义。同时,由于该项目的开发建设将有利地推动当地经济发展,促进当地由资源优势向经济优势的转变,所以对地方经济的发展有较强的借鉴意义。通过介绍镇沅金矿田的自然状况,包括矿床特征、开采技术条件和矿产的环境,提出了镇沅金矿田的开采难点。在此基础上,综合考虑自然、技术和环境因素,设计了镇沅金矿田的开采方案。针对镇沅金矿田建设的主要建设内容,分析了各种成本费用投资估算,并对主要成本费用要素进行了分析,在此基础上,对镇沅金矿田建设的经济效益和社会效益进行了评价。最后提出了镇沅金矿田建设的保障措施。主要是从组织结构、工程进度以及做好尾矿库安全管理等方面提出了建议。镇沅金矿田的开采经济可行,社会效益显著。
[Abstract]:In recent years, the changes of international gold prices and the increasing difficulty of mining gold resources, In February, 2004, Yunnan Commodity auction Center Co., Ltd. auctioned the fixed assets (excluding mineral rights) of the original Zhenyuan gold mine. China Gold Group bid for 47 million yuan, China Gold Group Technology Co., Ltd. held by Yunnan Gold Co., Ltd. formally took over. Zhenyuan gold mine administrative division belongs to Zhenyuan Yi nationality, Hani nationality, Lahu nationality autonomous county Heping Township in Yunnan Province, and the east part of the south part of the ore field belongs to Jianxin Township of Xinping County, Yuxi area. Based on the desk literature review, this paper summarizes and analyzes the main ways and methods of gold mining at home and abroad, as well as the relevant suggestions and suggestions of different scholars and experts on the cost control of gold mining. This paper analyzes the natural and mineral reserve conditions of Zhenyuan gold ore field, studies the construction cost of Zhenyuan gold ore field from the aspects of site selection, equipment purchase, personnel input, etc. The measures to control the development cost of gold ore field are put forward from the point of view of organization and guarantee. With the further decline of the international gold price and the sharp decline of gold resources in China, the mining cost of gold ore field is rising constantly, which is facing a great challenge to the survival and development of domestic gold field development enterprises. The research in this paper will promote the development and utilization of refractory gold resources in China, which is of great significance to promote the healthy, stable and sustainable development of gold industry. At the same time, the development and construction of the project will promote the development of local economy and promote the transformation from resource superiority to economic advantage, so it has a strong reference significance for the development of local economy. By introducing the natural situation of Zhenyuan gold ore field, including deposit characteristics, mining technical conditions and mineral environment, the difficulties of mining Zhenyuan gold ore field are put forward. On this basis, considering the natural, technical and environmental factors, the mining scheme of Zhenyuan gold ore field is designed. According to the main construction contents of Zhenyuan gold ore field, various cost and cost investment estimates are analyzed, and the main cost and expense elements are analyzed. On this basis, the economic and social benefits of Zhenyuan gold ore field construction are evaluated. Finally, the guarantee measures for the construction of Zhenyuan gold ore field are put forward. Suggestions are put forward mainly from the aspects of organization structure, project schedule and safety management of tailings reservoir. The exploitation of Zhenyuan gold ore field is economically feasible and the social benefit is remarkable.
