Coal mining collapse area cultivation water source reconstruction method applicable to complicated mountainous areas

Abstract

The invention relates to a coal mining collapse area cultivation water source reconstruction method applicable to complicated mountainous areas. The coal mining collapse area cultivation water source reconstruction method comprises water source engineering, water discharge engineering and auxiliary engineering. A water discharge channel is connected with an inlet of a desilting pool through a pipeline, an outlet of the desilting pool is communicated with a drain grating pool, an outlet of the drain grating pool is communicated with an inlet of a reservoir, decontaminated and desilted rain enters the reservoir, an outlet of the reservoir is communicated with an irrigation channel with low terrain through a water delivery pipeline, and finally, a water source is conveyed into farm land. According to the agricultural irrigation water source recovery method, the local rainfall resources are sufficiently utilized, in addition, the water storage and water preservation capability of water source facilities is enhanced and reinforced, the irrigation water requiring problem of local farm land is solved, and great convenience is brought for the agriculture construction in the complicated mountainous areas.

Description

technical field [0001] The invention relates to a farming water source reconstruction method, in particular to a farming water source reconstruction method suitable for coal mining subsidence areas in complex mountainous areas. Background technique [0002] In some coal mining mountainous areas with complex topography, the surface water mainly comes from natural precipitation. After the coal seam is mined, the original mechanical balance of the surface rock mass is destroyed, resulting in cracks and cracks in the rock formation. The original cracks are developed, and the groundwater connectivity is good. A large-scale groundwater falling funnel is formed underground, which makes the wells and springs dry up, the streams cut off, and the groundwater level in the boreholes drops, causing damage to groundwater resources. According to the field investigation, all the arable land in the coal mining subsidence area is dry land, and the original paddy fields are all used for dry fa...
