Embodiment Construction

[0066] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0067] like figure 1 As shown, the method for adopting the analogy method of an embodiment of the present invention to carry out a rough technical and economic evaluation of coal resources includes:

[0068] Obtaining the location coefficient of the coal mining area to be evaluated, the location coefficient is determined through the location economic evaluation of the coal mining area to be evaluated;

[0069] When the coal mining area to be evaluated is divided into a plurality of successively adjacent sub-coal seams to be evaluated, the average well depth of each sub-coal seam to be evaluated is obtained;

[0070] For each sub-coal seam to be evaluated:

[0071] Carrying out technical and economic evaluation on the sub-coal seam to be evaluated to determine...

Abstract

The present invention provides a method for rough technical and economical evaluation of coal resources by analogy, which includes: establishing a graded score algorithm, quantifying the characteristics of the technical and economical cost evaluation index system, and realizing the geological, technical and economical evaluation of coal resources; The location coefficient and well depth coefficient algorithm quantify the external environment and vertical change characteristics of the coal mining area to be evaluated, and realize the economic evaluation of the location environment characteristics; A full-cost price evaluation scheme for coal seams. Based on the empirical method of recovery rate, under the constraints of economic feasibility, technical feasibility, and environmental protection feasibility, the evaluation of economic and technical available reserves in the target coal mining area is realized. The results are highly reliable and easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of energy availability evaluation, in particular to a coal resource availability evaluation method. Background technique [0002] At present, the methods that can be used for the economic evaluation of coal resources mainly include the net present value method (Net Present Value, referred to as NPV) and the geological analogy method. [0003] The net present value method is used to evaluate the economic availability of mines that have been produced, and it is necessary to estimate and determine sales revenue, total investment in mine construction, depreciation and recovery of fixed assets, and total costs (including: mining costs, beneficiation costs, sales expenses, management Expenses, financial costs, mineral resources compensation fees and land reclamation fees), taxes and other related evaluation parameters, the evaluation accuracy is relatively high. However, there are many disadvantages: (1) It is en...
