The Method And Computer System Study Of Improving The Efficiency Of Mining Rights Assessment

Minerals are the common human labor and natural product, under the conditions of market economy, the mineral resources is a kind of commodity, has value. Its value is useful mineral resources are valuable basis, and the scarcity of mineral resources is valuable conditions, the value of mineral resources of the mining right evaluation theory is the theoretical basis.Mining right evaluation method is based on the value of mining, through the geological, economic, and mathematical methods, geology and mineral, economy and other parameters of mining quantitative, evaluate and estimation of value. According to the geological exploration and evaluation objects, the evaluation purpose, usually, mainly through the mining right evaluation approach, market and gains three ways as cost approach to assessment, including discount cash flow method, method and evaluation of geological factors, comparable switch sequence method.Mining right market and the influence of multifarious factors of complex, mining value determines the mining right evaluation subjectivity strong very difficult, Because the evaluation of mainly is the accuracy of history data and the data, and introduces some assumptions, then the main is some of speculative judgment, the evaluation is more complex, exploration is more difficult. On one hand, the mining right evaluation program for evaluation of selecting parameters when different angles, will often make evaluation value of different, On the other hand, the accuracy of the evaluation and selection of assessment method has the very big relations.Therefore, only the selected scientific and reasonable evaluation method and the accurate assessment of parameters can draw an objective, fair and rational mining right evaluation value.Through the theoretical study and practice, the mining right evaluation method that the existing theories foundation, not fully reflect the defects of the objective and scientific evaluation of the mining right evaluation principle, make the scientific rationality and accurate value to ensure objectivity, At the same time, people in various evaluation parameters of the correct definition, accurate itself to understand and control, to a great extent affecting the credibility of the assessment.It is based on the mining right evaluation to promote our mining in modern economic development plays an important role in the deep understanding, this paper expounded the traditional, common kinds of mining right evaluation method, the content and the applicable rules of main evaluation method and evaluation parameters under some important to determine the scientific analysis of the targeted at China, in mining right evaluation methods used on the basis of the theory of limitations, further discusses the uncertainty of commercial decision-making, can effective project assessment of real options method of mining right evaluation in our field application value.And the use of improved real options method to verify the case.
