Abstract
The invention discloses a synergistic treatment method for grassland cracks and bulges, which comprises the following steps: s1: stripping surface soil 20cm to 30cm from the ground surface of the crack zone and the ridge zone; s2: excavating soil in the ridge to 20cm below the original elevation before ridge forming; s3: adding water into the soil dug out of the ridge belt, stirring the soil into slurry, and filling the slurry into the crack belt; s4: leveling soil on two sides of the crack with the step height larger than 5cm into a gentle slope with the angle not larger than 15 degrees; s5: covering the stripped surface soil on the shaped cracks and ridge according to the thickness of 20 cm; s6: slightly tamping, and planting by selecting local grassland vegetation; the method solves the problem that the soil and the vegetation can not be effectively protected while the prior method can not realize the treatment of the cracks and the bulges of the grassland area.
Description
Technical Field
The invention relates to the field of coal mining, in particular to a synergistic treatment method for grassland cracks and bulges.
Background
After underground coal mines in grassland mining areas in China are mined, a large number of cracks and uplift damages are generated on the surface of the grassland, and the existing treatment method is to flatten an uplift zone and cut a slope on a step crack zone, so that desertification of the grassland soil and great damage to vegetation are caused. Therefore, the invention can realize the purpose of effectively protecting the soil and the vegetation while treating the cracks and the ridges of the grassland area by the synergistic treatment methods of surface soil stripping, ridge soil backfilling crack zones, land leveling and the like.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a synergistic treatment method for grassland cracks and bulges, and solves the problem that the soil and vegetation can not be effectively protected while the treatment of the cracks and bulges in the grassland area can not be realized by the conventional method.
The technical scheme adopted by the invention is that the method for cooperatively treating the cracks and the bulges in the grassland comprises the following steps:
s1: stripping surface soil 20cm to 30cm from the ground surface of the crack zone and the ridge zone;
s2: excavating soil in the ridge to 20cm below the original elevation before ridge forming;
s3: adding water into the soil dug out of the ridge belt, stirring the soil into slurry, and filling the slurry into the crack belt;
s4: leveling soil on two sides of the crack with the step height larger than 5cm into a gentle slope with the angle not larger than 15 degrees;
s5: covering the stripped surface soil on the shaped cracks and ridge according to the thickness of 20 cm;
s6: slightly tamping, and planting by using local grassland vegetation.
The synergistic treatment method for the grassland cracks and the bulges has the following beneficial effects:
the soil in the raised area of the grassland surface is dug and matched with the soil filling of the crack area, and the integrated cooperative treatment can ensure the harmony and unity of the landform and landscape of the grassland and ensure the full protection of the original states of the grassland soil and the vegetation.

Detailed Description
The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and it will be apparent to those skilled in the art that various changes may be made without departing from the spirit and scope of the invention as defined and defined in the appended claims, and all matters produced by the invention using the inventive concept are protected.
As shown in fig. 1 to 3, a method for the cooperative treatment of cracks and ridges in a grassland comprises the following steps:
the method comprises the following steps: stripping the first surface soil 1 and the second surface soil 5 which are 20cm to 30cm from the ground surface of the crack zone and the ridge zone;
step two: excavating soil in the ridge to 20cm below the original elevation before ridge forming;
step three: adding water into the soil 4 dug out of the ridge belt, stirring the mixture into slurry, and filling the slurry into the crack belt 2;
step four: leveling soil on two sides of the crack with the step height larger than 5cm into a gentle slope 3 with the angle not larger than 15 degrees;
step five: covering the stripped surface soil on the shaped cracks and ridge according to the thickness of 20 cm;
step six: slightly tamping, and planting by using local grassland vegetation.
