Study On Vegetation Recovery Of Huolinhe Coal Mine

Development and utilization of coal resources led to a series of ecological problems, mine area has become a typical serious damage to ecosystems, their ecological and environmental problems have become a restricted area of sustainable development and even coal regional ecological security of the hidden risk Youqi yes coal mine mining, will result in greater environmental problems. To further improve mining environment, conservation of ecological restoration of mining investment costs, accelerate the speed of recovery, while ensuring the ecological restoration of long-term benefits, the paper Huolinhe opencast coal mine restoration techniques in-depth study to explore the mine for the restoration of new technologies theory and practice to provide rehabilitation support.In this study, selection of plants by seeding selected areas more suited to the cold, drought-tolerant plant species; through the Application of humic acid humic acid revealed alternative substrates of peat soil as a foreign soil feasibility, and draw the foreign soil substrate using the region of origin of the humic acid and humic acid powder particles and surface configuration of a reasonable solution; by Spraying technology demonstration projects test and research, in-depth study of the technical and wet spray Spraying broadcast technology in the restoration of mine Huolinhe feasibility of the application. Through the present study, by the following major conclusions:(1) Caragana microphylia Lam, Artemisia, Elymus, lespedeza, Melilotus suaveolens Ledeb, Garcinia spp.and other plants in the tested plants performed well as Huolinhe goal of mine vegetation species;(2) In the theory and practice, humic acid peat soil as an alternative to foreign soil substrate was feasible, with the fertilizer and top soil, humic acid in Huolinhe application of mine are good prospects for restoration.(3) Technology is a Huolinhe Spraying vegetation of mine better construction techniques, with good prospects, can be large area; Wet Spray Technology in construction is more appropriate for the season and also to achieve better the greening effect, due to relatively lower priced, better conditions in the soil slope, wet seeding techniques using vegetation, but also has some prospects.
