A Classification Method of Eco-geological Environment Based on Coal Resource Exploitation

Abstract

A classification method of eco-geological environment based on the development of coal resources, which belongs to the field of eco-geological environment protection, solves the lack of consideration in the prior art of combining different geological environments and ecological environments on the surface of the mining area before implementing coal mining activities . Based on the investigation of relevant data such as regional ecology, hydrology, and geology, the present invention combines the fuzzy Delphi hierarchy process and the weighted fuzzy C-means clustering method to judge and determine different ecological geological environment types. According to the existing ecological hydrogeological data, the present invention can quickly and effectively divide different ecological geological environment types, determine the ecological geological characteristics and their sensitivity to coal resource mining activities, and protect the precious diving resources in similar arid and semi-arid areas. , maintain the fragile ecological environment and choose the appropriate coal mining method to realize the development and utilization of coal resources to provide a scientific basis, which is of great significance to water conservation and coal mining in the fragile ecological environment of Northwest China.

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...
