Embodiment Construction

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0039] (1) Case introduction

[0040] Located at the northern end of the Loess Plateau in northern Shaanxi, the mine has a semi-arid climate with less rainfall. The landform type is aeolian sand landform, and the vegetation type is mainly sand vegetation. The strike length of a working face is 1660m, the inclined length is 350m, and the average inclination of the coal seam is 1°. The average buried depth of the coal seam is 350m, and the average ...

Abstract

The invention discloses a western eolian deposit sand area coal mining subsidence treatment method. The method comprises the steps that (1) a ground affected range is determined according to storage conditions and mining conditions of coal seams and combination with mining subsidence influencing parameters; (2) governance areas are divided according to subsidence influencing types and degrees to determine the distribution and the scale of three-ring models; and (3) corresponding treatment measures and processes are selected according to different governance positions. Based on eolian deposit sand area mining subsidence distribution rulers, and guided by desertification control theories and technologies, the subsidence treatment areas are scientifically divided, the treatment process and measures are optimized, and the crack filling, the desertification control, the water and soil conservation and the vegetation recovery are combined to promote the eolian deposit sand area coal mining subsidence ecological environment improvement.

Description

Technical field [0001] The invention relates to the treatment of ecological civilization in coal mine areas, in particular to a new technology and a new method for the treatment of coal mining subsidence in western aeolian sand areas. Background technique [0002] As my country's energy resource strategy moves westward, the western region is becoming an important coal production base. A large amount of coal resources are located in aeolian sand landform type areas. The ecological environment of the aeolian sand area is fragile. The surface subsidence and collapse cracks caused by coal mining cause changes in the surrounding shallow soil water, which in turn affects the growth of vegetation and intensifies the desertification process. At present, the research on subsidence and damage of this type of mining area mainly focuses on monitoring and evaluation. How to manage this kind of subsidence in a scientific and reasonable manner is still lacking in in-depth research. The invent...
