Embodiment 1
[0020] Embodiment 1, the present invention provides a technical solution: a three-dimensional ecological restoration method for a coal mining subsidence area, comprising the following steps:
[0021] S1: Measure the length and width of the subsidence area and the depth compared to the ground level with the range finder, and sample the soil in each area to obtain the data information of the subsidence area;
[0022] The information includes: area of subsidence area, land water content, soil composition and depth of subsidence area, the position of area a is determined according to the depth of subsidence area, and the positions of area b and c are divided according to the water content of the land;
[0023] S2: According to the obtained information, the subsidence area is divided into three parts: a. Aquaculture area, b. Cultivation area, c. Waterproof soil loss area;
[0024] The specific method of plot division is that the water area is Area A, based on the water content of...

Abstract
The invention discloses a three-dimensional ecological restoration method for a mining subsidence area. The three-dimensional ecological restoration method for the mining subsidence area comprises the following steps of: S1: through a range finder, measuring the length and the width of a subsidence area and the depth, which is relative to the ground plane, of the subsidence area, carrying out soil sampling on each area, and obtaining the data information of the subsidence area; S2: according to the obtained information, dividing the subsidence area into three parts: a) an aquaculture area, b) a cultivation area and c) a water and soil loss prevention area; and S3: enabling the water bottom of the a) area to be extruded out of parts of soil, selecting an arid season, utilizing an agricultural machine to dig residual soil, keeping the water bottom to be flat, transforming the water body of the a) area to form the aquaculture area, arranging a detection system to monitor the water body, and arranging a water source conveying system. The three-dimensional ecological restoration method for the mining subsidence area can monitor the environment of the water body of the a) area, and enlarges a cultivated land repairing area to the greatest extent on the basis of the water content of soil, various ecological areas are mutually linked to realize a purpose of mutually accelerating repairing, and therefore, the subsidence area is recovered to achieve an expected effect.
Description
technical field [0001] The invention relates to the technical field, in particular to a three-dimensional ecological restoration method for a coal mining subsidence area. Background technique [0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. Coal mining subsidence is the phenomenon and process of rock formation movement and surface subsidence caused by underground mining in coal mines, also known as "mine rock formation and surface movement". After the minerals are extracted, the original mechanical balance state inside the rock mass around the mining area is destroyed, causing the rock strata to move, deform and destroy; [0003] In my country, the ecological restoration of subsidence areas mainly adopts deep-dug pad shallow reclamation technology, and according to the level of water level, aquaculture areas, landscape areas, farming areas, etc. are built to restore coal mining subsidence areas. Environmental restoration in sub...
