Construction method of ecological safety barrier in waste mine restoration area

Abstract

The invention discloses a construction method of an ecological safety barrier in a waste mine restoration area. The construction method comprises the following steps: S1, before mining of a mining area, removing soil on the surface layer and the subsurface layer of a mine in a digging manner, storing the soil in a proper environment, after mining of the mine is completed, placing the stored soil back to the original place, storing the soil for 3-5 days, taking a certain amount of the soil in a unit range for testing, and detecting the pH value, humidity and nutritional condition of the soil. According to the construction method, the construction process of the ecological safety barrier in the waste mine restoration area is simple, the effect is obvious, treatment can be carried out from multiple aspects of the pH value, humidity and nutritional condition of the soil, the soil quality is improved, improvement is accelerated, and the period of restoration construction is shortened; and meanwhile, a good condition is provided for vegetation growth by broadcasting fertilizers, the air permeability and water permeability of the soil are improved by animals, a stone-built slope protection structure is stable, and the purposes of leakage prevention and blocking can be efficiently achieved.

Description

technical field [0001] The invention relates to the technical field of mine restoration, in particular to a method for constructing an ecological safety barrier in an abandoned mine restoration area. Background technique [0002] Population, resources, and environment are the main issues facing the sustainable development of today's society, and it is imperative to achieve a balanced and harmonious development of population, resources, and environment. From a theoretical perspective, the sustainable development of the local environment is a subset of the stable operation of the society as a whole. The management and restoration of the mine ecological environment is the key to the sustainable development of the local environment. Accordingly, it is of great significance to explore and analyze the restoration of abandoned mine land productivity and the maintenance of mine ecosystem by comprehensively utilizing the principles and methods of restoration ecology and resource eco...

Problems solved by technology

Cooperating with measures such as water storage reconstruction, deep digging and shallow pad technology, and agricultural and forestry reconstruction, it can accelerate the recovery of vegetation; while the ecological reconstruction of tailings sites mainly uses artificial greening to promote ecological recovery through ecological reconstruction of gangue and ecological reconstruction of subsidence areas; The ecological reconstruction of the soil field mainly uses technologies such as soil and vegetation restoration of the dump site, soil stabilization technology of the dump site, and vegetation species selection and allocation technology; the ecological reconstruction of the subsidence area is mainly based on the development direction of the mining subsidence area after reconstruction, and comprehensively considers agriculture and aquaculture. , construction and other factors, formulate corresponding ecological reconstruction plans, the traditional construction method of ecological safety barriers in abandoned mine restoration areas can not be maintained for a long time, and the efficiency is poor, and the constructed mines are easy to be abandoned again
