(I) Environmental Impacts of Mining Projects 1. Impact of Ecological Environment Destruction: Due to the exploitation and drainage of underground space during the construction of the mine, the groundwater is unbalanced, causing a significant drop in regional groundwater levels, resulting in a shortage of ground water resources. Cultivated land desert, causing serious ecological damage.
2. Geological structure damage: During the construction of the mine, due to the hollowing out of some strata, the pressure of the formation and the geological structure are unbalanced, resulting in deformation and destruction of the stratum structure, and this effect will always extend to the ground. Local land subsidence will cause the cultivated land to sink, which will not only endanger the original building (construction) on the ground, but also cause the village road to be relocated and the house will be destroyed. It will also cause the mountain to crack, collapse and landslide, and the damage to the natural environment of the ground will threaten Ground buildings and personnel safety in the mining area.
3. Waste discharge pollution impact: The discharge of wastewater, waste residue and waste gas from a large amount of construction mud is directly harmful to construction workers. Mining and construction personnel to directly face the rock dust (or coal dust) in a small face, dust, toxic gases, radioactive poison with corrosive and groundwater, endangering the health of construction workers and occupational diseases are very serious . Excavation of mine solid waste (such as gravel and industrial waste such as liver and stone) not only encroaches on the site and farmland, but also causes deterioration of the atmosphere, water quality and soil around the mine, destroying vegetation and ecological landscape; The object is also radioactive, and the damage is even more serious. Therefore, the treatment of mine waste and industrial waste is also an important part of mining project environmental protection, avoiding domestic water pollution and living environment damage.
(II) Environmental protection work requirements during the construction process 1. Optimize engineering design. The newly developed mining area (mine) should strive to optimize the design of all environmentally relevant projects under the premise of fully carrying out environmental impact assessment, and minimize the impact on the environment.
2. Main engineering design of the mine. Reform should be carried out on the layout of mine ground industrial sites. According to the idea of ​​establishing production, production services and living services, the production organization of the mining area will be divided into several systems according to functions. Comprehensive planning with the principles of specialization, centralization, enterprise and systematization.
3. Design of environmental protection engineering. Environmental protection projects should meet environmental protection requirements on the basis of environmental impact assessment, and should be reviewed and approved by the environmental protection department.
4. Adhere to the formal procedures for the construction and acceptance of environmental engineering projects, ensure that environmental protection projects are completed and put into production on schedule, and strictly implement the "three simultaneous" policy. All construction projects that discharge "blue waste" and polluted the environment must strictly ensure that the environmental protection project and the main project are simultaneously designed, constructed, and invested in production and use.
