Granite mine slash ecological green returning technology

Abstract

The invention belongs to the agricultural field, and particularly relates to the improvement of a granite mine slash ecological green returning technology. In order to solve the problems, the granite mine slash ecological green returning technology is provided. In order to achieve the purposes, the granite mine slash ecological green returning technology includes the following steps that firstly, land preparation is performed before construction, a ballast blocking wall is arranged on a stacking slope toe, a drainage ditch is excavated according to the peripheral terrain of a region, upstream rainfall runoff is drained out of the periphery of a mining area, meanwhile, when a hole is excavated in a slope, exposed stones are removed, the built soil stacked slope toe is cleared up in a centralized mode, and a soil body is retained; secondly, earth backing is carried out before renovation and green returning, the requirement for thickness is 1 m, a slope cutting and grading method is adopted on a mine wall soil texture slope, a horizontal trapezoid table face is formed, a bamboo joint building groove is then formed, and a water interception facility is built on the top of the slope; thirdly, a broadcast sowing method is adopted for performing greening.

Description

technical field [0001] The invention belongs to the field of agriculture, and more specifically, the invention relates to an improvement of a method for ecological regreening of granite mine remnants. Background technique [0002] Due to large-scale mining in the mining area, a large amount of forest vegetation has been destroyed, the ground surface is exposed, and waste soil and ore slag are piled up everywhere. The soil is loose and highly permeable. Under the strong impact and cutting of rainwater and surface runoff, landslides and mudslides are easily generated, causing serious soil erosion and causing great harm to the ecological environment. Mainly in. [0003] 1. Destruction of agricultural production The vegetation in the mining area is destroyed, and the loose soil is eroded down the slope by the erosion of the water flow, causing water to wash and press the sand in the downstream farmland, the soil is desertified, it is difficult to re-cultivate, and the crops are...

AI Technical Summary

Problems solved by technology

[0003]1. Destruction of agricultural production and mining areas The vegetation is destroyed, and the loose soil is eroded by the water flow, falling down the slope, causing the downstream farmland water to wash and press the sand, and the soil to be deserted , it is difficult to resume farming, and the grain crops are lost, causing great losses to local farmers

[0004]2. Harmful water conservancy facilities. Due to serious soil erosion, a large amount of sediment silts up rivers, ponds, canals and other water conservancy facilities, seriously affecting Jinjiang flood drainage and Reduce the irrigation efficiency of water conservancy facilities, which poses a great threat to industrial and agricultural production and people's lives and property

[0005]3. Pollution of drinking water sources. During the mining process, a large amount of sand and dust, harmful physical and chemical substances flowed into the river, causing water source pollution

[0007]5. Geological disasters are caused. Some mines in the mining area are not constructed according to the mining plan, and the operation is performed on an over-slope. Geological disasters such as landslides and landslides often occur. Safety production has brought great harm
