Problems solved by technology

For a long time, due to the lack of effective governance responsibility system and vegetation restoration model, serious ecological and environmental problems such as soil erosion and geological disasters have occurred, and soil and water pollution have been caused, affecting the social stability of mines and the normal production and life of local people. and health
[0003] Because the mine spoil contains a lot of gravel, its water holding capacity is poor and its nutrients are low. Although the soil of the spoil platform is mechanically compacted, the slope soil is loose and lacks the cohesion between natural soil particles. The anti-scouring ability is poor; the spoil is artificially piled up, with large height difference, steep slope, and its shape is extremely unstable, which has the topographic conditions for severe soil erosion; the unique habitat conditions of mine dumps make it difficult for vegetation to rapidly recover in a short period of time. growth, so that the mine dump is in a state of no vegetation cover for a long time

Embodiment 1

[0091] The invention provides a method for water and soil conservation and ecological greening of a mine dump, comprising the following steps:

[0092] Step 1, repairing the mine dump, the top of the mine dump is trimmed to a platform area with a slope of 13 degrees or less, and the slope of the mine dump is trimmed to a slope of 45 degrees or less;

[0093] Step 2. Deep plow and dry the platform area twice, the depth of deep plowing each time is 40cm, and the drying time is 5 days each time;

[0094] Step 3: Plow the platform area twice, the depth of each plowing is 20cm, and mix the fermented and decomposed soil with grass seeds into the soil at the same time for the first plowing, and the surface of the platform area per square meter is averagely mixed with Fermented decomposed soil 0.05m 3 , the second plowing and burying the biomass strip bag into the soil at the same time; the fermented and decomposed soil contains 40% fermented and decomposed fertilizer, and the biomas...

Embodiment 2

[0111] The invention provides a method for water and soil conservation and ecological greening of a mine dump, comprising the following steps:

[0112] Step 1, repairing the mine dump, the top of the mine dump is trimmed to a platform area with a slope of 13 degrees or less, and the slope of the mine dump is trimmed to a slope of 45 degrees or less;

Abstract

The invention discloses a water and soil conservation and ecological greening method for a mine waste dump. The water and soil conservation and ecological greening method comprises the following steps: trimming the top part of the mine waste dump into a platform area, and trimming the slope gradient of the mine waste dump to be less than or equal to 45 degrees; deeply ploughing and airing the platform area twice; ploughing the platform area twice; repeatedly ploughing the platform area twice every 30-40 days until the earth surface vegetation coverage rate of the platform area exceeds 40%, then ploughing the platform area once again, and burying biomass strip bags into soil again during ploughing; spraying fermented and decomposed soil with grass seeds to the slope surface of the mine waste dump; arranging a transition vegetation hanging device at the joint of the platform area and the slope surface; hanging a plurality of water storage vegetation blocks below a vegetation belt in rows; and transplanting shrubs on the open space among the plurality of water storage vegetation blocks in rows on the slope surface, and transplanting shrubs on the platform area in rows. The method provided by the invention can rapidly restore vegetation coverage of the mine waste dump and effectively preserve water and soil, so the occurrence of natural disasters is avoided.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation and ecological restoration, in particular to a method for water and soil conservation and ecological greening of a mine dump. Background technique [0002] The development and utilization of mine mineral resources has effectively promoted the development of the national and local economy and society, but a large amount of spoil is produced in the process of mineral resource development, and a series of large-scale dumps are formed. Loss is a prominent ecological and environmental problem in the process of mineral resource development and construction. For a long time, due to the lack of effective governance responsibility system and vegetation restoration model, serious ecological and environmental problems such as soil erosion and geological disasters have occurred, and soil and water pollution have been caused, affecting the social stability of mines and the normal production...
