[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.
