The Application Of Fuzzy Multi-attribute Decision Making Method To Mineral Resource Expoitment

Our country is the biggest country of the world in population, which is also the biggest country of the mineral resources, but our country is a poor country on per capita of the resource quantity, and the per capita of mineral products is below half of the world standards of occupancy volume. After entering into the 21st century, to guarantee that mineral resources of economic sustainable development our mineral resource is insufficient seriously. The degree of development of mineral resources reflects the important signs of progress of human society and scientific and technological level, which limits the speed of national economic development of our country directly and relates to the realization of the strategic objective of our country in the 21st century at the same time, and which is important to rational utilization of the resource, increasing the wealth of society, increasing economic benefits, protecting the natural ecological balance.The Tonglushan copper-iron mine is the key mine of Hubei Daye nonferrous metals corporation, and it is one of the large-scale mines of nonferrous metals of our country too. The mine is adopted to open-mining and underground-mining jointly, and the open-mine is divided into north and south stope. One of the existing problems of the mine at present is: when the south open stope is over in2005, where does the open north stope start for the sake of optimizing economic benefit and social benefit and environmental benefit of the mineFacing to this problem, based on the large number real data of mine, in view of fuzzy attribute and complexity attribute existing in mine production, this paper applies fuzzy multi-attributes decision method to a lot of feasible technology, economy rational for schemes to appraise to proposes . The model that this method adopts is not only fully expressing fuzzy attribute of the mine, but also making the resolution ratio highBased on the research, this decision-making model is applied to Tonglushan mine for starting the open north stope, the result shows: this method is scientific, simple and accurate, and it offers rational basis for the decision making of the mine.
