Embodiment

[0029] A kind of mine dump slope vegetation restoration method, such as figure 1 and figure 2 The following steps are shown:

[0030] 1) Build an intercepting ditch 2 at the top of the slope of the mine dump, and build a drainage ditch 3 at the slope surface and foot of the slope.

[0031] When constructing drainage ditches on slopes, the drainage ditches should be set up every 150m along the horizontal direction, that is, the two ends of the drainage ditch are respectively connected with the intercepting ditch 2 at the top of the slope and the drainage ditch 3 at the foot of the slope. .

[0032] Such as figure 1 As shown, the drainage ditch adopts a trapezoidal cross-section, that is, the cross-section of the drainage ditch is trapezoidal, with a bottom width of 35-40 cm, a depth of 28-32 cm, and a thickness of 18-22 cm.

[0033] 2) Repair the construction area and clean up the slope surface.

[0034] In the early stage of construction, the construction area should be ...

Abstract

The invention relates to a slope vegetation restoration method of a mine dump, and belongs to the field of ecological slope restoration of mine dumps. The slope vegetation restoration method comprisesthe following steps of constructing an intercepting ditch and a drainage ditch, cleaning slope debris, flatting the slope surface, laying fixation networks, conducting spray-seeding on a soil matrixlayer, conducting spray-seeding on a plant seed layer, covering non-woven fabrics and conducting water spraying curing. The slope vegetation restoration method can well guarantee the slope structure and stability, also achieves the effects of afforestation, beautification and construction of ecological landscapes, and is simple in construction technology, easy to implement, high in efficiency andsuitable for large-area application.

Description

technical field [0001] The invention relates to a method for restoring vegetation on slopes of mine dumps, and belongs to the field of ecological restoration of mines and slopes of mine dumps. Background technique [0002] The surface layer of the slope of the dump site is mainly composed of unbroken and directly piled up waste slag and stones after ore washing, and the particle size is very uneven. Therefore, it is difficult to natural weathering and crushing in a short period of time, and it is loosely accumulated with large gaps. The corresponding water holding capacity is also poor, and the soil nutrients are relatively poor. The stacking of a large amount of spoil and slag in the dump site has changed the original mechanical composition and structure of the soil. Under the action of heavy rainfall, strong wind and gravity, surface erosion, gully erosion, and gravelized surface erosion and subsidence are prone to occur. New soil erosion such as landslides, collapses and...
