Research On Closed Mine Environmental Recovery And Management In Fushun City

Mineral resources in the mining, processing and smelting process, to mine immeasurable negative impact on the environment, and cause direct or indirect, immediate or long-term, acute or chronic damage affecting the surrounding environment and human health aspects. Fushun, Liaoning Province, is a result of the rise of coal comprehensive industrial city, also the integration of mining and urban resources city. For decades, due to over-exploitation of mineral and energy has been nearly depleted, many mines have been successively closure stop mining, and the impact of mining on the environment still exists, serious damage to the original topography, vegetation degradation, desertification, water pollution, crop growth damage. Increasingly prominent environmental problems caused by the mine municipal government attaches great importance to, and implementation of "Castle Project" within the city, the mine will damage the environment to recover. Thus, it needs to solve a long-term process that requires a lot of manpower, material and financial resources to resolve.In this paper, closed environmental restoration of Fushun for the study, through the investigation of the status of the mine closed and environmental destruction, determined the mine closed environmental problems, there are:geological disasters, occupation and destruction of land resources, soil and water pollution, landscape and vegetation damage. These issues will come with the weighted Comparison Method major environmental problem, which is the focus of governance as a problem.The main problem of Fushun mine closed environmental is the destruction of vegetation, followed by the pressure of occupied land, avalanches, landslides and mudslides, is less affected by water pollution, soil pollution, ground subsidence, ground subsidence.Based on the analysis results into the need to focus on governance, sub key governance issues, general governance, develop appropriate control measures. Destruction of vegetation and land issues pressure to account for the principle of green cover, planting vegetation and adapt to the surrounding environment, taking control methods trees, shrubs, turf, such as the combination of slope used mainly planted climbing plants, hanging on foreign soil seeding, vegetation bags engineering and other technical means to govern. Avalanches, landslides and mudslides have adopted the construction of retaining wall, playing pile, block project, drainage works and other effective prevention. Water pollution, soil pollution and ecological restoration to take chemistry methods to repair governance, the contamination level down to a minimum. Ground subsidence and collapse using unfilled reclamation and fill method, the loss of farmland to change cropping patterns to obtain economic benefits.
