Embodiment 1

[0046] Taking a mine dump in the north as the area to be treated, after the slope of the area is covered with soil and planted, the topsoil is leveled.

[0047] Set a trapezoidal groove with a wide top and a narrow bottom on the slope top of the dump site after soil covering and planting. The groove is set at a distance of 40 cm from the edge of the slope top of the dump site. The width of the groove is 30 cm. The depth is also 30cm.

[0048] A whole piece of grass curtain is composed of a plurality of strips of grass with a width of 1.2m and a porosity of 40%. One end of each strip of grass is laid from the end of the groove away from the surface of the top of the slope and the grass curtain Fit it on the surface of the groove wall, and then fix the grass curtain in the groove with wooden stakes, and the other end is extended from the groove and laid along the longitudinal direction of the slope from the top of the slope to the foot of the slope.

[0053] Taking a mine dump in the north as the area to be treated, after the slope of the area is covered with soil and planted, the topsoil is leveled.

[0054] Set a trapezoidal groove with a wide top and a narrow bottom on the slope top of the dump site after soil covering and planting. The groove is set at a distance of 45 cm from the edge of the slope top of the dump site. The width of the groove is 40 cm. The depth is also 40cm.

[0055] A whole piece of straw curtains is composed of a plurality of strips of grass with a width of 1.4m and a porosity of 50%. One end of each strip of grass is laid from the end of the groove away from the surface of the top of the slope and makes the grass curtain Fit it on the surface of the groove wall, and then fix the grass curtain in the groove with wooden stakes, and the other end is extended from the groove and laid along the longitudinal direction of the slope from the top of the slope to the foot of the slope.

Embodiment 3

[0060] Taking a mine dump in the north as the area to be treated, after the slope of the area is covered with soil and planted, the topsoil is leveled.

[0061] Set a trapezoidal groove with a wide top and a narrow bottom on the top of the slope of the dump after soil covering and planting. The groove is set at a distance of 50 cm from the edge of the slope of the dump. The width of the groove is 50 cm. The depth is also 50cm.

[0062] The whole grass curtain is composed of a plurality of long strips of grass with a width of 1.5m and a porosity of 60%. One end of each strip of grass is laid from the end of the groove away from the surface of the top of the slope and makes the grass curtain Fit it on the surface of the groove wall, and then fix the grass curtain in the groove with steel bars, and the other end is extended from the groove and laid along the longitudinal direction of the slope from the top of the slope to the foot of the slope.

Abstract

The invention relates to a shading and water retention method for a waste dump site of a mine, which belongs to the technical field of repair and treatment of the waste dump site of the mine. The shading and water retention method for the waste dump site of the mine comprises the following steps: disposing a ditch groove on the top of a side slope of the waste dump site after soil is covered and plants are built, fixing one end of a straw curtain to the ditch groove, paving the other end along the slope surface of the waste dump site, and then fixing by pressing the soil at the foot of the slope. The shading and water retention method can effectively resist runoff scouring, can shade and preserve soil moisture, and enables germination rate and survival rate of seeds to be improved.

Description

technical field [0001] The invention relates to the technical field of repair and treatment of mine dumps, and in particular to a shade and water conservation method for mine dumps. Background technique [0002] Dump site, also known as waste rock site, refers to the place where mining waste is discharged intensively. The dump site is a huge artificial loose cushion body, which has serious safety problems. The instability of the dump site will lead to mine soil disasters and major engineering accidents, which will not only affect the normal production of the mine, but also cause the mine to suffer huge losses. Economic losses. [0003] At present, part of the treatment in the shading and water retention method of the dump is not to cover anything on the slope, and part of the treatment is to cover the broken surface of the dump with non-woven fabric or shade net. Uncovered things are likely to cause runoff erosion, while covering with shade nets is likely to reduce the sha...
