Abstract

The invention discloses a vegetation recovery technology for a coal gangue mountain of a mining area, belonging to the field of ecological recovery technology for soil and water conservation. The technical scheme comprises: a slope stabilization measure of the horizontal-stage soil preparation and layer-upon-layer compaction stacking technology; a matrix improvement measure: earthing and flattening on the slope surface, and approximately forming a terrace-shaped strip small plane along the contour line direction on the slope surface; planting amorpha fruticosa, wherein the planting specifications are: the cluster space is 35cm, each cluster includes 2-3 plants, and the planting depth is properly 1cm below the original soil mark; sealing the pit and treading down; staggering the plants of the upper and lower lines; after the planting, watering and fixing the root in time; maintaining: performing timely maintenance and management after the planting, checking the seedlings and filling a vacancy; and performing afforestation optimally certain years after gangue removal, wherein March is the best time for the afforestation so that the plants can go through the seedling recovery period early. Through the scheme, the vegetation recovery of the coal gangue mountain of the mining area is better, the manufacturing cost is lower, and a good ecological recovery effect and a good visual effect can be realized.

Description

Mining area coal gangue hill technology for recovering vegetation

Technical fieldThe invention belongs to soil and water conservation ecological recovery technology field, mainly relate to a kind of mining area coal gangue hill technology for recovering vegetation.

Background technologyCoal gangue hill is in the mining industry abandoned land environment of mining area to be destroyed the most typical one type, and its land occupation condition is extremely abominable, the plant growing difficulty.Traditional coal gangue hill improvement method mainly is on the gangue massif, to spray the comprehensive shutoff formation of slip casting plugged zone with mechanical means, and spray transfer mud covers the formation transition zone comprehensively on plugged zone, on transition zone, sprays the mud that contains grass filling type plant and covers formation plantation layer comprehensively; Mainly be to be the basis with the engineering measure; And grass seeds is mainly local weeds, and its construction costs is high, and soil and water conservation effect is poor; Be difficult to play and improve the ecological environment, improve the purpose of region view.

Summary of the inventionDefective in view of prior art exists the purpose of this invention is to provide a kind of mining area coal gangue hill technology for recovering vegetation, and its technical scheme design comprises as follows: the form that adopts biological control measure to combine with engineering measure:

1) stability of slope measure, horizontal rank wholely are stacked technology with compacting layer by layer: coal gangue hill pushes away the side slope design of loosing after smooth and cuts the slope to open level be three grades, every grade of high 5m in slope; The wide 3m in horizontal rank; Ratio of slope: first order 1:1.75, second level 1:1.55, third level 1:1.20.First and second grade side slope adopts stone masonry bow member grass planting, and skirt, mortar flag stone plain stage of slope and gutter thereof, domatic fringing are protected in the end, slope; Third level side slope is with grass type slope protection greening technology.

2) base material improvement measure, the soil moved in to improve the original earthing can be taked in surface, horizontal rank, the about 10cm of thickness of earth covering; After domatic earthing was smooth, the isohypse direction on domatic roughly was made into the banded facet of terrace-type, and let the false indigo of preparing plantation that certain loose soil is arranged, and during whole ground, must guard against along the isohypse direction and was made into both ends high, middle low.

3) plantation false indigo, the contour cultivation ditch of the dark 20cm of first-class high excavation on the horizontal band-like plane, organic fertilizer in ditch (chicken manure etc.); And be affixed by phosphate fertilizer, and false indigo is adopted plant division root rudiment plantation, and the plantation specification: clump is apart from 35cm; Every clump 2～3 strain, the depth of planting is advisable for about 1 centimetre to surpass the original soil seal, then the envelope hole; Tread, the up-downgoing plant is staggered, and normal root in time waters after the plantation.

4) back maintenance management is in time planted in maintenance, looks into seedling and fills a vacancy.

5) the afforestation time carries out after should being selected in the certain time limit of discharge refuse, spends seedling-slowing stage ahead of time in order to make plant, and the afforestation time is best with March.

Adopt behind this programme the vegetation recovery of mining area coal gangue hill better, and cost is lower, can reach good restoration of the ecosystem effect and visual effect.

The specific embodiment:

The mining area coal gangue hill technology for recovering vegetation schematic design that the present invention proposes comprises as follows: the form that adopts biological control measure to combine with engineering measure:

Claims
