specific Embodiment approach
[0015] The method for fast reclamation and management of coal gangue hills in semi-arid sandstorm area of the present invention, its preferred specific implementation mode is:
[0016] Include the following steps in order:
[0017] Reshaping and transformation; pad soil covering with sand; setting up rain-collecting bed surface; erecting sand barrier; using grass to promote irrigation and cultivation or combination of shrub and grass and cultivation; reclamation management and prevention of coal gangue re-ignition.
[0018] The plastic modification includes:
[0019] The gangue pile platform is compacted, leveled, slope cut and load reduced, and a slope of 1:1.5 is formed around the platform.
[0020] The described pad soil covering sand includes:
[0021] 50cm of sand shall be covered after 15cm of cushion soil on the countertop and side slope of the gangue platform.
[0022] Said setting rain collecting bed surface includes:
[0023] The table top of the platform cover...

[0034] Specific examples, such as figure 1 , figure 2 , image 3 Shown:
[0040] (5) Using grass to promote irrigation, combining shrub and grass and cultivating;
[0041] (5) Reclamation management to prevent re-ignition of coal gangue;
[0042] The above-mentioned coal gangue hill plastic transformation, its method is to comprehensively prepare the platform and side slope of the gangue hill, level it and take a solid shot, and cut the side slope to form a side slope of 1:1.5, so as to achieve the purpose of stabilizing the side slope .
[0043] The step of covering sand with pad soil is to cover 50 cm of sand with 15 cm of pad soil on gangue hill slope and platform base, so as to achieve the effect of improving substrate and promoting growth with water ad...

Abstract
The invention discloses a rapid reclamation control method for coalgangue dumps in a semiarid windy desert area. The rapid reclamation control method comprises the following successive steps of performing land shaping and reclamation; filling soil and spreading sand; installing rainwater harvesting beds; building a sand barrier; promoting shrubbery by grass and cultivating or combining the shrubbery and the grass and cultivating; managing the reclamation to prevent coalgangue from reburning. The rapid reclamation control method for the coalgangue dumps in the semiarid windy desert area is rapid, simple and direct, economic and practical, is lasting in benefit, and is suitable for rapid reclamation control of the coal gangue dumps in the semiarid windy desert area.
Description
technical field [0001] The invention relates to a technology for reclamation and management of coal gangue hills, in particular to a method for rapid reclamation and management of coal gangue hills in semi-arid sandstorm areas. Background technique [0002] Shenfu Coalfield is located in the border area of Shanxi, Shaanxi and Inner Mongolia on the edge of Mu Us Sandy Land. However, this area is located in an area with fragile ecological environment and severe desertification in my country, and shows strong transitional characteristics in terms of climate, soil, vegetation and other factors, especially with the increase of human activities, the impact of ecological environment on mining The response is very sensitive, especially the appendages produced by coal mining—coal gangue wastes occupy a large amount of land resources and destroy the original surface ecosystem. According to the monitoring of the Shaanxi Sand Control Research Institute, a 10hm 2 There are more than 4...
