Method for dividing ecological and geological environment types based on coal resource development

摘要

A method for dividing ecological and geological environment types based on coal resource development, relating to the field of ecological and geological environmental protection, and used for solving the problem that the prior art lacks consideration of the combination of the different geological environments and ecological environments of the earth surface in mining areas before implementing coal mining activities. On the basis of investigation into materials related to the ecology, hydrology, and geology of an area, the present invention combines a fuzzy Delphi hierarchy analysis method with a weighted fuzzy C-means clustering method to determine different ecological and geological environment types. On the basis of existing ecological, hydrological, and geological materials, the present invention can quickly and effectively divide different ecological and geological environment types, and determine ecological and geological features and the sensitivity thereof to coal resource exploitation, in order to protect cherished phreatic resources in arid and semi-arid areas, and provide a scientific basis for the selection of suitable coal mining methods for the development and utilisation of coal mining resources whilst maintaining fragile ecological environments, and therefore being of great significance for water conservation and coal mining in the fragile ecological environments of the north-west of China.
