[Abstract]:The present situation of mining enterprises in China is that large and medium mines are few and small mines are more. Small mine is an important force in the development of China's mining industry. Therefore, in the evaluation of mining rights, there are a large number of items in the evaluation of mining rights in small mines. Because of the characteristics of small mines, the income rights and interests method is widely used in the evaluation field when selecting the evaluation method. This paper introduces some methods commonly used in foreign mining right evaluation, such as discounted cash flow method, comparable market value method, exploration cost multiple method and rough estimate method. It provides a reference for the development and perfection of mining right evaluation in China. The commonly used methods in China are discounted cash flow method, geological factor evaluation method and income equity method. However, the evaluation of mining rights in our country started late and has only been more than ten years' experience. It is not perfect in all aspects, and there are some problems in the process of evaluation. With the rapid development of mining economy, the industry of mining right evaluation is becoming more and more active, so it is of great significance to study the improvement and optimization of the parameters in the evaluation method. In the light of one of the methods of mining right evaluation in small mines, the income rights and interests method has the phenomenon that the calculation of recoverable reserves is inaccurate in practice, the human factors have great influence, the evaluation process is not standardized and objective, which results in inaccurate evaluation results. In this paper, four parameter optimization methods are put forward to solve the problem of lack of geological data for small mines, such as the uncertainty of reserves, the non-standard values of mining rights' equity coefficient and discount rate, and the evaluation results of benchmark price test. Then, taking the project "Mining right Evaluation of Huoyanshan calcite Mine in Qingyang County, Anhui Province," as an example, through full-time geological exploration personnel and appraisers, on-site geological exploration, estimating reserves, determining the amount of design losses, and finding out the traffic location of mines in detail, Geological characteristics, mining technical conditions, processing performance and mining rights market situation, check and verify the legality of the mine, and collect the relevant evaluation data. Combining with the theory of mining right evaluation and using the method of parameter optimization, the paper calculates the important parameters and other indexes, such as recoverable reserves, mining rights equity coefficient, discount rate, etc., and obtains the evaluation value. Finally, the evaluation results are tested with the base price. By comparing the value of mining right assessed with the original method and the value of mining right assessed by parameter optimization method, and the final result of land and resources bureau review and filing, this paper draws a conclusion. The factors affecting the value of mining rights are fully reflected in the evaluation, and the influence of human factors is also reduced. The method of parameter optimization is feasible.
