HJ 651-2013Technical specification of eco-environmental protection and reclamation for mining(On trial) (English PDF)

Foreword

To implement the "People's Republic of China Environmental Protection Law", "People's Republic of China Environmental Impact Assessment Law" and "the State Council Opinions on Strengthening Key Environmental Protection Tasks "to regulate the development of mineral resources in the process of Ecological Environment Protection and Restoration Work to promote mine ecological environment protection, development of this standard.

This standard specifies the mineral resources exploration and mining process, dump, open pit, tailings, mine roads, Technical guidance mine industrial site, subsidence area, waste rock fields, mines and other contaminated sites and mine ecological environment protection and recovery Governance Surgery requirements.

This standard was proposed by the Ministry of Environmental Protection Natural Ecology Protection Department.

This standard is developed by the Ministry of Environmental Protection Science, Technology organization.

This standard is mainly drafted by. Environmental Protection Department of the Nanjing Institute of Environmental Sciences, Ministry of Environmental Protection Standards Institute, Sinosteel Maanshan Institute of Mining Research Co., Ltd. (the State Environmental Protection Mine Solid Waste Treatment and Disposal Engineering Technology Heart) and the Cold and Arid Regions Environmental and Engineering Research Institute.

This standard MEP July 23, 2013 for approval.

This standard since July 23, 2013 implementation.

The standard explanation by the Ministry of Environmental Protection.

Mine Ecological Environment Protection and Restoration Technical Specifications (Trial)

1 Scope

This standard specifies the exploration and mining of mineral resources during mining ecological environmental protection requirements, including dump, open-air Stope, tailings, mine roads, mining industrial sites, subsidence area, farm waste rock, mine ecological environment contaminated sites Guiding the technical requirements of conservation and restoration of governance.

This standard applies to coal, metal ores, non-metallic minerals, oil and gas mining, coal bed methane, gravel mining and other land mineral resources exploration, Ecological Environment Protection and Restoration after mining and mine closure process.

Ecological Environment Protection and Restoration of uranium, thorium and other radioactive mineral resources can be developed for implementation.

3 Terms and Definitions

The following terms and definitions apply to this standard.

4 General requirements for mine ecological environment protection and recovery Governance

4.1 prohibited legally designated nature reserves, scenic spots, forest parks, drinking water source protection areas, cultural relics Prohibited location, geological heritage protection areas, basic farmland protection areas and other important ecological protected areas and other laws and regulations Mining area. Prohibited the landscape important break in the road, both sides of the fairway and important ecological sensitive targets visible range Bad significant open pit mining.

4.2 Mineral resources development activities should be consistent with national and regional planning of the main functional areas, ecological function zoning, environmental protection regulations Planning requirements, to take effective preventive and protective measures to avoid or mitigate the development of mineral resources activities caused ecological damage and environmental Pollution.

4.3 adhere to the "prevention first, combining prevention with control, process control" principle, the mine ecological environment protection and recovery through governance Exploitation of mineral resources of the entire process. According to the priority tasks of mine ecological environment protection and recovery management reasonably determine the mine ecological Protection and partition recovery and management, optimize production and living space pattern mining. The introduction of new technologies, new methods, new technology to improve mine Mountain ecological protection and restoration governance.

4.4 All mining enterprises should control requirements of this standard, implementing mine ecological environment protection and recovery management program.

Various types of site restoration 4.5 after treatment should achieve. security and stability, to humans and animals and plants does not pose a threat; on the surrounding environment is not Pollution; harmony with the surrounding natural environment and landscape; restore the basic functions of land, according to local conditions to achieve sustainable utilization of land Use; the overall regional ecological functions are protected and restored.

5 Mine ecological protection

5.1 Construction of mineral resource base in the key (important) people's governments at all levels of the ecological functions of the area determined by the national and local, shall enter Line ecological impact and economic loss assessment, according to the results of the assessment and the relevant provisions of the Controlled exploitation, reduce the ecological space Occupancy, does not affect the regional leading ecological functions. In the water shortage, environmental capacity is small, fragile ecosystems, earthquakes and ground Mass disaster prone areas, to strictly control the exploitation of mineral resources.

5.2 before mining should investigate the status of biodiversity in the region that could affect the mining areas and a variety of mining activities, for National or local flora and fauna or protected ecosystems, or to be taken in situ conservation and other measures to protect the ex situ conservation of biological diversity Mine Sex.

5.3 Alpine region open pit mining, setting dump and tailings, should be stripped of turf layer concentrated conservation, restoration satisfy conditions Promptly after transplantation, restore vegetation; strictly control the construction site and construction of a temporary road area and scope, reduction of surface vegetation damage.

5.4 desert sand and mineral resources development should avoid the area prone to erosion and ecological degradation zone, reducing mining, dumping and transport and other activities on soil crust, vegetation and sandy gravel screen area damage and disturbance; dump, yard and tailings and other venues should be taken around Block and cover other anti-erosion measures.

5.5 Mineral Resources Development erosion sensitive areas should be scientifically set up the open pit, waste dump, tailings and yard and take flood prevention, Conservation Measures drainage, slope protection, engineering Landang, to reduce the destruction of natural vegetation.

5.6 In the basic farmland protection areas as mining, mine subsidence area governance programs should be combined to determine the priority backfill mining area, to prevent Secondary treatment table; the need to protect water exploration blocks, should take effective measures to avoid damage to groundwater.

5.7 mining solid wastes generated should be stacked in a special place, and to take measures to prevent secondary pollution; prohibits the river, lake Water Park, reservoirs and flood discharge channels geotechnical, oily garbage, mud, cinder, coal and other solid wastes.

5.8 assess the impact of mining activities on surface water and groundwater, to avoid the destruction basin water balance and water environment pollution; and mining areas it should be kept a safe distance between the river environment, to prevent the mining of river creatures, riparian vegetation, river water environment function and anti Hong'an Full devastating effects.

Private road alignment should be around 5.9 Mining avoid environmentally sensitive areas and environmentally sensitive points, to prevent an adverse environmental protection goals ring.

All types of construction site before 5.10 Dump, stope, tailings, mine dedicated roads, depending on the soil type of topsoil should be Peeling. Mine stripping of soil tillage, layer, and respond to heart and backfill soil alone peeling, stripping topsoil thickness love Under the condition of not less than 30cm; for mine uncultivated soil collection, a separate deal with topsoil stripping, if the thickness of topsoil Less than 20cm, at least 20cm thick soil layer of soil below the soil close to the heart and then the table together constitute a separate stripping Off; alpine region stripped topsoil should be retained divot peel thickness of not less than 20cm. Topsoil stripping can not be shop Regulation has to cover the site, select the appropriate venues storage, enclosure and take other measures to prevent soil erosion.
