Ecological and geological environment type dividing method based on coal resource exploitation

Abstract

The invention discloses an ecological and geological environment type dividing method based on coal resource exploitation, belongs to the field of ecological and geological environment protection, andsolves a problem that the different ecological and geological environments of the land surface in an exploited region are not combined and considered in the prior art before the exploitation of coals. According to the invention, an FDAHP (Fuzzy Delphi Analytic Hierarchy Process) and a weighted fuzzy C-man clustering method are combined on the basis of the investigation of the ecological, hydrological and geological data of the region, so as to judge different ecological and geological environment types. According to the conventional ecological, hydrological and geological data, the method canachieve the quick and effective dividing of different ecological, hydrological and geological environment types, determines the ecological and geological features and the sensitivity of coal resourceexploitation activities, provides the scientific basis for the protection of the valuable latent water resources in similar arid and semi-arid regions and the implementation of the exploitation and utilization of the coal resources through a proper coal exploitation method while a fragile ecological environment is maintained, and is of great significance of water-preserved mining in northwest regions with the fragile ecological environments.

Description

technical field

[0001] The invention relates to the field of ecological geological environment protection, in particular to a method for classifying ecological geological environment types based on coal resource development. Background technique

[0002] Coal resource is an important natural resource, and it is also the basic source of energy and materials for many industries such as steel, cement, chemical industry, etc., accounting for more than 70% of China's primary energy consumption structure. With the gradual depletion of coal resources in eastern China, the focus of coal industry development has shifted rapidly to western China. In the next 10 years, the coal output of five provinces in western China including Shanxi, Shaanxi, Inner Mongolia, Ningxia and Xinjiang will exceed 70% of China's total coal output. However, the average annual rainfall in western China is scarce, and the amount of evaporation is huge. It is an arid-semi-arid area with poor water resources a...
