Embodiment Construction

[0016] A method for water and soil greening and restoration in mining areas, the method is realized by the following steps:

[0017] Step a: Utilize a bulldozer to flatten and tamp the ground in the mining area, and then lay and tamp a subsoil layer with a thickness of 80cm on the tamped ground; the subsoil layer is formed by mixing slaked lime, clay, and slag in a mass ratio of 1:1:2 ;

[0018] Step b: After the subsoil naturally settles and produces cracks, lay a core soil layer with a thickness of 40cm on the subsoil layer, and seal the cracks by the core soil layer; the core soil layer is composed of slaked lime, clay, water in mass ratio 2:4:2 mixed;

[0019] Step c: laying a topsoil layer with a thickness of 15 cm on the core soil layer and compacting it; the topsoil layer is formed by mixing slaked lime, clay, and slag in a mass ratio of 1:1:2;

[0020] Step d: Excavate several inverted trapezoidal ditches on the surface soil layer; each inverted trapezoidal ditches a...

Abstract

The invention relates to a mining area greening repair technology, in particular to a mining area water and soil greening repair treatment method. The method solves the problems of water and soil lossand land desertification caused by many years of mining of a mining area. The mining area water and soil greening repair treatment method is realized by adopting the following steps of a, bulldozingand tamping the ground of the mining area by using a bulldozer; b, laying a core soil layer with the thickness of 40 cm on a bottom soil layer; c, laying a surface soil layer with the thickness of 15cm on the core soil layer and performing tamping; d, digging a plurality of inverted trapezoidal ditches in the surface soil layer; e, laying branch layers with the thickness of 10 cm on the ditch bottoms and the ditch slopes of the inverted trapezoidal ditches; f, digging a longitudinal ditch in each trapezoidal ridge; g, filling each U-shaped groove with an organic soil layer; and h, after drought-enduring shrubs survive stably, drawing out all the U-shaped grooves from the longitudinal ditches to be reused. The method is suitable for mining area greening repair.

Description

technical field [0001] The invention relates to a mining area greening restoration technology, in particular to a mining area water and soil greening restoration treatment method. Background technique [0002] After years of mining in the mining area, the original organic soil layer and surface vegetation will be severely damaged, which will lead to soil erosion and land desertification, which will induce natural disasters such as landslides, collapses and mudslides. Based on this, it is necessary to invent a new method of greening and restoration of mining areas to solve the problems of soil erosion and land desertification after years of mining in mining areas. Contents of the invention [0003] In order to solve the problems of water and soil loss and land desertification caused by years of mining in the mining area, the invention provides a water and soil greening and restoration treatment method in the mining area. [0004] The present invention is realized by adopti...
