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. Repair the mine dump, trim the top of the mine dump to a platform area with a slope of 13 degrees or less, and trim the slope of the mine dump 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 biomass strip bag is ...

Abstract
The invention discloses a method for water and soil conservation and ecological greening of a mine dump, comprising the following steps: trimming the top of the mine dump to a platform area, and trimming the slope of the mine dump to a slope less than or equal to 45 degrees ; deeply plow and dry the platform area twice; plow the platform area twice; every 30-40 days, repeat the plowing of the platform area twice until the vegetation coverage on the surface of the platform area exceeds 40%, after that, turn the platform once again, While plowing, bury biomass strip bags into the soil again; spray fermented and decomposed soil with grass seeds on the slope of the mine dump; set up transitional vegetation hanging devices at the junction of the platform area and the slope; A plurality of water-storage vegetation blocks are hanged in rows under the belt; shrubs are transplanted in the open space between the rows of a plurality of water-storage vegetation blocks on the slope surface, and the shrubs are transplanted in rows on the platform. The method of the invention can quickly restore the vegetation coverage of the mine dump, effectively maintain water and soil, and avoid the occurrence of natural disasters.
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...
