The Method Of Environment Management And Technology Of Ecological Restoration Of Hui Quanyu Limestone Mining Area In Mengyin City

With the improvement of living standards and the enrichment of material life, the people pay more attention to the requirement of environmental aspects and so on. The hazard and potential geological hazard problems such as high and steep quarry face, slag heap, mountain vegetation destroyed, soil and water loss phenomenon is increasing, and the resulting collapse, landslides and other geological disasters caused by strip mining quarrying of limestone Huiquanyu mining area in Mengyin city Shandong province will be treated by two methods which are environmental management and ecological restoration.First of all, the general situation of the natural environment geological environment background conditions and mine geological environment of limestone mining area has carried on the exploration; Then, based on the geological environment feature of the mine, geological environment characteristic, mining virescence maintenance engineering and irrigation condition have be analysed. We definituded the objectives and tasks of restore the natural ecological environment; eliminate the geological hazard; reduce water loss and soil erosion, return the mountain in green.Environmental governance taking technical measures such as slope modification, backfill, anchor according to the principle of "adjust measures to local conditions, scientific and reasonable"; carrying out the cubic metro engineering following the relevant technical requirements and standards of prevention and control of geological disasters, land reclamation, cleaning up waste slag heap to tie up land, field leveling by the way of high skin pass low fill, modifying the face of high and steep slope. Greening design is fundamental key with native tree species, with a strong drought resistance, high ornamental value of landscape tree species, and connecting with the climate conditions and natural environment in line with the principles of aesthetics, economic and practical by the means of "tree, irrigation, cane" to take biological measures and biological technology to restore vegetation. Treatment scheme have been compared based on the principle of the above, and scheme design of the earth-rock work and greening engineering have also been carried out, picked out by slurry masonry retaining wall plate and laying bricks or stones platform to pile retaining wall greening slope for the optimal solution.Although the mine environmental governance could not be recovered before the original rocks of natural geological features, but the geological environment after the governance will produce significant social benefits and environmental benefits with appeared in the beautiful scenery at the same time; It will have important significance to restore natural ecological function area, to promote the development of the tourism industry, to promote the harmonious development of economic society in Yimeng mountain area. Through the project implementation, the construction of mine environment and ecological restoration can be drived to point with surface of the MengYin city can be popularized in the province, providing the reference for the future mine environment management and ecological restoration. Make contributions to the ecological construction of Shandong.
