Description
Technical Field
The utility model relates to an ecological restoration technique is applied to heavy metal stope side slope ecological restoration, like mines such as copper mine, pyrite, lead-zinc ore, especially is fit for being arranged in the copper mine, concretely relates to strong acid heavy metal mine stope rock matter side slope ecological restoration growth bag structure.
Background
Along with the progress of metal mine mining, often can form a large amount of naked rock slopes, if not carry out ecological management in time, will aggravate the soil erosion and water loss in the mining area, still can influence the slope stability when serious. Aiming at the rocky side slope of a metal mine stope, the current ecological restoration has the following problems:
(1) soil deficiency
The soil is the foundation of plant growth, and the plant absorbs various nutrients through the root system in the soil, so that the rock slope soil has few components, and the rock cannot keep the nutrient elements required by plant growth, thereby ensuring that sufficient soil is an important precondition for ecological management of the rock slope.
(2) Poor surface stability
Under the influence of the weathering effect, the surface structural plane of the rocky slope develops and is easy to fall off, the plant root system is not easy to root, and even if the plant grows on the surface layer, the root system can be pulled off due to the falling of the surface rock mass, so the influence of the weathering effect on the surface rock mass is reduced, the stability of the surface rock mass is increased, and the plant can stably grow for a long time.
(3) Deficiency of nutrient elements
Basic nutrients such as N, P, K, organic matters and the like required by plant growth are difficult to store in rocks, and the lack of nutrient elements is a great obstacle to the colonization and growth of plants. To ensure the normal growth of plants on the rocky slope, enough nutrient elements must be ensured on the slope.
(4) Strong acidity and high heavy metal content
The metal mines are accompanied by a lot of sulfides, are easily acidified when exposed to air, form acid water and affect the growth of plants, and in addition, the metal mines are often accompanied by heavy metals such as copper, zinc, lead and the like, and the heavy metals have toxicity to plant cells and affect the growth of plants, so before ecological restoration, the acidity and the heavy metals need to be improved.
Based on the difficulties, to ensure the effect of ecological restoration, effective soil improvement is firstly achieved, the side slope in the restoration area can be kept to be sufficient soil and nutrient base materials, most of the applications at home and abroad are net hanging soil dressing spray seeding, namely, about 10cm of spray seeding base materials are sprayed after a steel wire net is laid on the slope, the stability of the surface layer of the slope is poor, the slope is easily washed and damaged by rainwater, and in addition, about 10cm of spray seeding base materials are too few to provide nutrient elements for plant growth. In addition, for ecological restoration of rock slopes, methods such as a floating platform, a fishbone hole method, a swallow nest method, a step blasting method and the like are applied at home and abroad, and the methods have the defect that the plant coverage rate is low, only can be limited to the fishbone hole, the swallow nest or the blasting step, and cannot cover plants on the whole slope.
