A treatment method for coal mining subsidence in the western aeolian sand area

Abstract

The invention discloses a method for controlling coal mining subsidence in aeolian sand region in the west, which comprises the following steps: the first step: according to the coal seam occurrence conditions and mining technology, combined with mining subsidence influence parameters, the ground influence range is determined; the second step : According to the impact type and degree of surface subsidence, divide the treatment area, and determine the distribution and scale of the three-circle model; the third step: select corresponding treatment measures and processes according to different treatment locations. Based on the law of mining subsidence distribution in aeolian sand areas and guided by the theory and technology of desertification prevention and control, the present invention scientifically demarcates subsidence area control zones, optimizes control techniques and measures, and combines crack filling with desertification control, water and soil conservation, and vegetation restoration. Combined, it will promote the improvement and improvement of the ecological environment of the coal mining subsidence in the aeolian sand area.

Description

technical field [0001] The invention relates to the management of ecological civilization in coal mining areas, in particular to a new process and a new method for the management of coal mining subsidence in the western aeolian sand area. Background technique [0002] With the westward shift of my country's energy resource strategy, the western region is becoming an important coal production base. A large number of coal resources are located in the aeolian sand landform type area. The ecological environment in the aeolian sandy area is fragile, and the surface subsidence and subsidence 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 is mainly focused on monitoring and evaluation. How to scientifically and rationally manage this type of subsidence is still lacking in-depth r...
