【摘要】：我國礦業(yè)企業(yè)的現(xiàn)狀是大中型礦山少，小型礦山多。小型礦山是我國礦業(yè)發(fā)展中一股重要的力量。因此在礦業(yè)權評估中，，小型礦山采礦權評估的項目就有較大數(shù)量，由于小型礦山自身的特點，在選擇評估方法時，收入權益法的簡便易行被評估界廣泛運用。 本文介紹了目前國外礦業(yè)權評估常用的一些方法，有貼現(xiàn)現(xiàn)金流量法、可比市價法、勘查費用倍數(shù)法和粗估法。為我國礦業(yè)權評估的發(fā)展和完善提供了參考依據(jù)。國內(nèi)常用的方法有：折現(xiàn)現(xiàn)金流量法、地質(zhì)要素評序法和收入權益法。但我國礦業(yè)權評估起步晚，至今才十幾年的經(jīng)驗，各方面還不夠完善，評估過程中存在著這樣那樣的問題。隨著礦業(yè)經(jīng)濟的迅速發(fā)展，礦業(yè)權評估這一行業(yè)也日趨活躍，那么研究其中評估方法中參數(shù)的改進和優(yōu)化就有重要的意義。針對小型礦山采礦權評估的方法之一—收入權益法在實踐中存在可采儲量計算有失準確，人為因素影響較大，評估過程不夠規(guī)范、客觀，造成評估結果有失準確的現(xiàn)象，本文提出了針對小礦缺乏地質(zhì)資料造成的儲量不明確、采礦權權益系數(shù)和折現(xiàn)率取值不規(guī)范、基準價檢驗評估結果的四種參數(shù)優(yōu)化方法。 之后以“安徽省青陽縣火焰山方解石礦采礦權評估”項目為例，通過專職地質(zhì)勘查人員和評估師現(xiàn)場地質(zhì)勘查、估算儲量，確定設計損失量，并詳細查明礦山的交通位置、地質(zhì)特征、開采技術條件、加工性能和礦業(yè)權市場情況，查證核實礦山的合法性，并收集相關評估所需資料。結合礦業(yè)權評估理論，運用參數(shù)優(yōu)化方法，對可采儲量、采礦權權益系數(shù)、折現(xiàn)率、等重要參數(shù)和其它指標進行測算，得出評估值，最后用基準價對評估結果進行檢驗，證明是符合要求的，通過對比分析運用原方法評估的采礦權價值和采用參數(shù)優(yōu)化方法評估的采礦權價值，以及國土資源局評審備案的最終結果，得出本文結論。評估中影響采礦權價值的因素得到較充分的體現(xiàn)，也減少了人為因素的影響，參數(shù)優(yōu)化方法切實可行。
[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.
