Abstract

The invention relates to a method for manufacturing a new type of mine restoration ecological blanket matrix. The porous water-storage clay is crushed into particles with a particle size of ≤5mm, and mixed with dried sludge at a volume ratio of 1.5-2.8:7.2-8.5. Uniform, adding grass seeds therein to make a new type of mine restoration ecological blanket matrix; the dried sludge is processed into a pH range of 7.5-9, a moisture content range of 45-50%, and a carbon-nitrogen ratio range of 15- 20:1, the organic matter content ranges from 10% to 30% in the dried sludge of urban domestic sewage treatment plants. The new ecological blanket matrix for mine restoration made by the invention can store water and purify rainwater at the same time, improve soil pores, create good water source conditions for the initial growth and germination of plant grass seeds and adapt to the environment, and improve the survival rate of herbal plants in mine restoration ecological blankets, especially suitable for It is suitable for mines and rock slopes with poor water retention and storage conditions.

Description

technical field [0001] The invention relates to a method for manufacturing a novel mine restoration ecological blanket matrix, which belongs to the technical field of mine restoration. Background technique [0002] Since the 1980s, with the rapid increase of the country's demand for mineral resources and the rapid development of the mining economy, the ecological environment damage caused by mining has become more and more serious, especially open-pit mining, which not only affects the natural landscape, but also causes environmental pollution. pollution, but also induce landslides, causing soil erosion and other geological disasters. Therefore, how to restore and rebuild the degraded mine ecosystem has become a topic of widespread concern around the world. The ecological restoration of mines is centered on the restoration of the ecological environment. It studies how to implement the restoration of the ecological environment of mines according to the actual situation, acco...
