Problems solved by technology

[0007] 1) Extensive excavation results in poor soil physical properties, lack of fertilizer, water, and low content of nitrogen, phosphorus and organic matter in mining wasteland
At the same time, the land is barren and the vegetation is degraded, which eventually leads to the formation of a large area of ​​artificial bare land in the mining area, which is easily washed by rainwater and aggravates the formation of soil erosion.
[0008] 2) The excavation of the ground and slope affects the stability of the mountain and s

Embodiment Construction

[0029] A greening matrix for ecological restoration of pulverized coal gangue, a greening matrix for ecological restoration of pulverized coal gangue, mainly using pulverized coal gangue as a matrix, wherein in the mixture of soil and gangue, the volume ratio of soil is: 10%~ 95%; the volume ratio of coal gangue is 5% to 90%.

[0030] When greening coal gangue as a substrate is mainly herb, the soil and gravel-like gangue are mixed in a volume ratio of 1:2.

[0031] In areas with dry climate and less precipitation, water-retaining agents can also be mixed in the mixture of soil and coal gangue. The water-retaining effect of nano-scale liquid water-retaining agent is obviously higher than that of ordinary water-retaining agent, and the water-retaining effect is better with the increase of dosage, which can increase the soil water holding capacity and increase the available water range and effective utilization of crops. The water retention effect of ordinary water retaining ag...

Abstract

The present invention discloses an ecology recovering greening substrate of coal gangue crushing material. The coal gangue crushing material is mainly used as substrate, wherein the volume ratio of soil in the compound of coal and coal gangue is 10%-95%, and the volume of coal gangue is 5%-90%. The using of waste of coal gangue can effectively improve the environment of waste mine, reduces the environment pollution and saves the cost for recovering ecology. The mixture of soil and coal gangue is also mixed with water-loss reducer. The application method of the invention is using the mixture of soil and coal gangue crushing material to the recovering and cultivation of herb or shrub for greening the coal gangue mine.

Description

technical field [0001] The invention relates to an ecological restoration matrix of a mining abandoned land, in particular to an ecological restoration greening matrix of pulverized coal gangue. Background technique [0002] Environment and development are major issues that the international community is generally concerned about, and a series of ecological, social and economic issues caused by the development and utilization of mineral resources, an important means that human production activities and economic growth depend on, are environment and development issues. one of the focal issues. [0003] According to statistics in 2008, there are more than 8,000 state-owned mining enterprises and more than 230,000 individual mining enterprises in my country. The destruction of the land and the environment by a huge amount of mining is quite astonishing. However, the land reclamation rate is only 2%, which seriously damages the land resources and ecological environment. Among...
