Coal resource sustainability evaluation method

Abstract

The invention relates to a coal resource sustainability evaluation method. According to the invention, a sustainability evaluation index system and a coordination evaluation model index system are constructed respectively, the sustainability of the coal resources is comprehensively evaluated by utilizing a sustainability evaluation index and a coordination evaluation model index, and the respective determinacy of the sustainability evaluation index and the coordination evaluation model index is respectively determined, so that the randomness and fuzziness of the system are considered. According to a coal industry ecological coordination model, a relationship between coal industry development and ecology is established, and the sustainable development condition of the coal resources in eachprovince is evaluated by utilizing a sustainability index determined by a sustainability comprehensive evaluation value and a coordination comprehensive evaluation value, so that a brand-new and morecomprehensive evaluation method is provided for evaluating the sustainability of the coal resources, and the accuracy of evaluating the sustainability of the coal resources is improved.

Description

technical field [0001] The invention relates to the technical field of coal resource evaluation, in particular to an evaluation method for coal resource sustainability. Background technique [0002] Scientifically evaluating the sustainability of coal resources and clarifying the factors and extent of the sustainable development of coal resources will help solve the problem of resource, environment, and economic imbalance. Therefore, the sustainable development of coal resources and its quantitative evaluation methods have been deeply studied, and the concept of coal resource sustainability has been proposed. [0003] At present, there are many methods for system comprehensive evaluation, mainly including the following methods and models: fuzzy comprehensive evaluation method, which considers the fuzziness of the system, and uses the degree of membership to express the fuzziness of the system; the extension model mainly uses the contradiction Analyze the system; Uncertain m...

AI Technical Summary

Problems solved by technology

The above models and methods solve the uncertainty of the system from different angles, but none of them can accurately express the distribution characteristics of each index, and the degree of certainty obtained is fixed, ignoring the fuzziness of the system, and unable to reflect the randomness of the system. sex

[0004] Moreover, the current research on the sustainability of coal resources mostly focuses on independent analysis from the aspects of economic and environmental coordination, resources and environmental coordination, etc., but rarely puts economy, resources, society, and environment in the same research system. And they are all based on the development of the entire mining industry or mining cities, and there are few specific analyzes of the relationship between the development of the coal industry and ecology

[0005] There are also inaccurate problems in the screening of indicators and the determination of grading thresholds after selecting indicators
