Problems solved by technology

The external dumps generated by open-pit coal mining will occupy a large amount of land, pollute the environment, and affect the normal life of human beings. Moreover, the exposed slope after stripping the topsoil has poor soil physical structure, extremely barren and poor water retention capacity. Not conducive to slope greening

preparation example Construction

[0024] Some embodiments of the present invention also provide the preparation method of above-mentioned slope greening matrix, it comprises:

[0025] S1. Mixing and fermenting biochar, livestock and poultry manure and microbial fermentation agent.

[0026] Specifically, for mixed fermentation, biochar and poultry manure are placed in the fermentation tank according to the ratio, humic acid is added, and they are put into the fermentation tank together. Then, add water again, so that the moisture content of the mixture is controlled at 50-65% during the fermentation process, and ferment at a temperature of 50-60°C until it becomes decomposed. Through the control of moisture content and fermentation temperature, a better fermentation effect is achieved, and livestock manure is converted into high-quality organic fertilizer.

[0027] S2. Mixing the fermentation product with other raw materials to obtain a slope greening substrate.

[0028] Specifically, before mixing the fermen...

Embodiment 1

[0034] Its raw material of the slope greening matrix of the present embodiment comprises the following dry weight components: 1000 parts of open-pit mining coal mine discharge, 25 parts of sheep manure, 0.8 part of biochar, 0.5 part of microbial agent, 3.5 parts of humic acid, 2.5 parts of water retaining agent and 0.1 part of adhesive.

[0035] Among them, the soil discharged from the open-pit coal mine is manually sieved through a 2mm sieve, and impurities such as gravel are removed and no harmful heavy metals that limit plant growth are contained. Biochar is prepared from corn stalks by low-temperature pyrolysis carbonization process. The microbial fermentation agent is a mixture of Bacillus and Bifidobacteria, and the mixing ratio is 1:1. Humic acid is prepared by microbial degradation of lignite. The water retaining agent is potassium polyacrylate. The binder is a mixture of sodium carboxymethylcellulose and β-cyclodextrin in a ratio of 1:1.

Abstract

The invention relates to the field of mine ecological environment management, in particular to a slope greening matrix and a preparing method and application thereof. The slope greening matrix is prepared from, by dry weight, 800-1,200 parts of open-pit-mining coal mine efflux soil, 10-30 parts of livestock excrement, 0.5-1 part of biomass charcoal, 0.25-0.75 part of microbial fermentation fungicide, 1-3.5 parts of a water-retaining agent and 0.05-0.25 part of a binding agent. The preparing method of the slope greening matrix includes the steps that the biomass charcoal, the livestock excrement and the microbial fermentation fungicide are mixed and fermented; fermentation products and the other raw materials are mixed, and the slope greening matrix is obtained. The open-pit-mining coal mine efflux soil is locally used as a main raw material of the greening matrix, resource utilization of the efflux soil is achieved, the slope greening matrix can effectively provide rich nutrients and moisture for slope vegetation growth, growth of plants is promoted, and the survival rate is increased.

Description

technical field [0001] The invention relates to the field of mine ecological environment management, in particular to a slope greening substrate and a preparation method and application thereof. Background technique [0002] With the rapid increase in the demand for mineral resources in economic development, the development and utilization of mine resources not only provides important raw materials and energy for social and economic development, but also brings air pollution, water pollution, soil pollution, vegetation destruction, land degradation and ecological A series of ecological and environmental problems, such as system imbalance, restrict the local social and economic development process, and even endanger human health. The external dumps generated by open-pit coal mining will occupy a large amount of land, pollute the environment, and affect the normal life of human beings. Moreover, the exposed slope after stripping the topsoil has poor soil physical structure, ex...
