Embodiment Construction

[0037] According to the characteristics of the development of subsidence cracks, the present invention makes good use of the situation and adopts the pattern of terraced fields separated by slopes for treatment. Fill the cracks with soil and build them together with the soil disturbance area to form horizontal terraces, retain the original vegetation in the non-disturbance area, and form slope-separated terraces in the treatment area, so that the runoff from the original slope can enter the horizontal field surface and increase soil moisture.

[0038] The specific implementation method is as follows:

[0039] (1) Governance model of terraced fields separated by slopes in fractured areas

[0040] The main characteristics of crack development are as follows: figure 1 Shown, crack width W, crack spacing L, crack depth D. In order to reduce the amount of earthwork transported abroad and control costs, local materials are used to build terraced fields separated by slopes. Use th...

Abstract

The invention discloses a coal mining subsidence crack treatment method based on the slope-separated terrace model. According to the development characteristics of collapse cracks, the slope-separated terraced field model is adopted for treatment: the cracks are filled with soil on the spot, and unified with the soil disturbance area Build horizontal terraces, retain the original vegetation in the non-disturbed area, and form slope-separated terraces in the treatment area, so that the runoff from the original slope can enter the horizontal field, increase soil moisture to promote crop growth, and improve the level of regional ecological reconstruction.

Description

technical field [0001] The invention relates to a treatment method for wide and large cracks in coal mining subsidence. Background technique [0002] In the western loess hilly area, the damage to the surface caused by coal resource mining is mainly subsidence cracks. Especially in the area where the coal seam is buried shallow and thick, there are often many large cracks with opening width greater than 50cm on the surface. Its main features are large width and depth, and the surface presents steps. As the working face advances, the surface presents periodic subsidence cracks, and the interval between cracks is the periodic breaking step of the basic top. Such cracks have a large impact and are difficult to control. At present, there is still a lack of specialized research and non-targeted governance technologies. Contents of the invention [0003] The purpose of the present invention is to provide a coal mining subsidence crack treatment method based on the slope-separ...
