Abstract

The invention discloses an agriculture reclamation comprehensive treatment method for a coal mining subsidence area. The method includes: performing overall agricultural and ecological planning on the coal mining subsidence area to determine reclamation area; planning one or more rivers with an irrigation function according to deep pit features and the reclamation area; filling the rest of shallow pits, medium pits and part of deep pits in a mode using pumping pipelines to convey materials so as to recover the farming ability of the land; repairing the deep pits of the coal mining subsidence area according to the plans above to form rivers capable of storing water. The method has the advantages that the agriculture reclamation problem of the coal mining subsidence area is solved, the agriculture, living and production water use requirements along the coal mining subsidence area are satisfied, and the method is simple, reasonable in design, low in treatment cost and good in effect.

Description

technical field

[0001] The invention relates to the technical field of land management in mining areas, in particular to a method for comprehensive management of agricultural reclamation in coal mining subsidence areas. Background technique

[0002] Since the large-scale mining of coal resources in the 1970s, it has driven social and economic development, but it has also brought many negative effects. my country's coal mining is mainly distributed in Anhui, Jiangsu, Shandong, Henan, Shanxi, Hebei, Heilongjiang, Inner Mongolia and other coal resource concentrated mining areas, which belong to plain basins. Due to the massive mining of underground coal resources, serious geological and ecological damage has been caused. Some rivers have been cut off, roads, bridges and culverts have broken and sunk, hydropower facilities have been damaged, and the ecological environment has deteriorated. In coal mining subsidence areas where water accumulates all the year round, the area of ​​...
