| On the basis of the research of Yunnan Province-Academy of China cooperative project抯 (Strategic programming of the prospecting for gold and the increasing of gold reserves in Yunnan province) sub-project 揝trategic programming of the yielding and prospecting conditions of the gold mines in Yunnan province? the author spent two years on carrying through this thesis dealing with many aspects, such as geology, managing science, economics etc. Several methods, mainly consisting of contrast analyzing, UV, trend analyzing, linear programming, are applied.1.Main contents:1.1The resources conditions of the gold mines in existence. Relevant targets are as follow:proved up reserves, retained reserves, retained three-grade reserves.1.2Estimating on the present geological technique economics targets of the gold mines, the targets are as follow:1.2.1Mining targets: excavated ore grade, ore yield, mining loss rate, ore dilution rate, ratio of ten thousand tons of ore to its excavation, ratio of overburden, excavating work efficiency, unit electricity consumption for excavation.1.2.2Ore processing targets: processed ore grade, daily ore processing capacity, reclaiming rate of mining and metallurgy, ore milling rate, ore processing efficiency and unit electricity consumption.1.3Analysis on the present yielding and managing parameters of the gold mines.1.3.1Parameters of production scale: mining and ore process planning scale, actual production capacity, excavation capacity, annual taxation total, industrial increasing, industrial gross output, annual staff number, energy and material unit consumption, facility configuration, output, sale and provincial market occupation rate.1.3.2Financial parameters: asset in-debt rate, net asset profit rate, total asset payment rate, asset taxation rate, capital value-retaining and value-increasing rate, social contribute rate, cost profit rate, mining staff productivity, production marketing rate, circulating asset turnover rate, unit comprehensive cost, circulating ratio, applied capital ratio, and so on.1.4Forecasts about the requirement for gold ore and planning for the development of the gold mines in Yunnan province. According to the gold yield and market requirement in Yunnan province, and applying to the trend analyzing method, the yield of the gold mines is predicted, and by the means of multi-target linear programming mathematical-economical model, the yield is taken apart, so as to optimize the beneficial result of the gold system of Yunnan province.2..Main achievements:1.1It has been at large researched on the natural economical geography conditions, which include natural geography, population, mineral resources, macro economical background and economical strategic layout of Yunnan province in the thesis, especially the research achievement on the regional economical background is coming to be the gist for mining exploration.1.2The original database of the gold mines in Yunnan province is established, which consists of the gold mines?resources sub-database, the geological economical technology sub-database and the production management parameters sub-database, combining with the explanation1graphs and texts. All above databases have done 憈he groundwork for the production dynamic managements, general strength estimation and resources optimization and collocation.1.3According to the gold mines?present data in Yunnan province, the mathematics-economics model is established. No. one is the gold mine systematical general estimation model that is established using UV method; No. two is the coming two years?resources optimizing and collocating model that is established using trend analyzing and linear programming method, which can make all Yunnan gold mines get the best profits.1.4Facing the international and domestic gold market varieties, it is suggested that Yunnan mining development strategic decision-making should adjust profoundly, the concrete measures is to cultivate the phosphor chemical industry, no... |
