Ecological sealing slurry flame retardation and vegetation recovery technology for coal gangue hill

Abstract

The invention discloses an ecological sealing slurry flame retardation and vegetation recovery technology for a coal gangue hill. The technology comprises the following steps: firstly, tidying up the landform of a coal gangue hill, and arranging a slope stability protection and slope surface water drainage system; secondly, perforating the prior fire source points and pouring alkaline slurry for fire extinguishment; thirdly, sprinkling alkaline blended sealing slurry on the surface layer of the coal gangue hill; fourthly, spraying ecological vegetation recovery slurry on the blended sealing slurry; fifthly, spraying and sowing seeds of shrub and herbaceous plants; sixthly, laying protective materials. By spraying ecological vegetation recovery slurry, the soil condition is provided for the plants to grow, simultaneously, the construction soil consumption and the construction cost are reduced through the slurry spraying technology, and the problem of difficult construction transportation can be overcome. The use of shrub and herbaceous plants can avoid the main root of the root system of arbor from extending into the inner layer, guiding the infiltration of water stream, and inducing oxidation and temperature rise of gangue; in addition, when coal gangue is applied again as an energy source substance, the standing forest of arbor can not be damaged. Because the formed soil layer is suitable for shrub and herbaceous plants to grow, therefore, the ecological principle can be met; vegetational type at late stages can be stably sustained, and good ecological effect can be generated.

AI Technical Summary

Benefits of technology

This patented describes how plants grow by applying fertilizers onto their surface instead of growing them directly with chemicals like nitrogen or sulfur dioxide gas (S02). By doing this, we reduce costs while maintaining stability and benefits during subsequent stages where greenery may have been damagingly affected due to exposure to these substances.

Problems solved by technology

This patented describes how important environmental issues arise from burning up tons of waste materials containing valuable metals such as copper or lead during coal production processes due to their potential negative impact on both natural environments (land) and human health caused through harmful chemicals released into our atmosphere when they break down over long periods of time). Additionally, there may exist concerns about future use of fossil fuels used throughout China' s economy, which could result in increased greenhouse gas emissions if unused fuel sources were burnt off too much before disposal. Therefore, efficient methods must be developed towards protective treatment and conservation of coal gobbles while addressing various challenges related to them.
