| China is the world's biggest producer and consumer of coal. Comparing with oil and gas, coal resources relatively abundant, and has obvious advantages in mining and using in our countury. It meant that the coal resources will still be irreplaceable, and be our main energy and important strategic material for a long time in the future. The coal industry will be long-term and stable in the fundamental position in national economy.The contradiction is inherent between development and utilization of mineral resources and environmental protection. Our country always goes to waste of resources and the cost of the environment of extensive development road in the development and utilization of mineral resources long-term since. With rapiding development of the mining construction in China, the mine environment pollution and destruction has become more and more serious.It has become a source of environment pollution and destruction and the important factor of social development in China. In recent years, along with the country paying attention to the mine geological environment protection and treatment work, the contradiction between mineral resources exploitation and environmental protection has become weak, by promoting mine environmental legislation, viewing mine environment, making formulate the mine environment protection plan, especially promoting the green mining demonstrative project construction in the mine environment, and striving to mine development and geological environment protection two not mistaken.It enhanced the sustainable development.This papper study abroad mine geological environment protection policies and technology, discusses using biological repair and geochemical engineering technology co-governance environmental pollution problems of the application and technical advantages.It summarizes Chinese scholars formed on the basis of consensus in the mine geological environment to restore a lot of research work, namely:One is advocated "green mining" mode, the implementation of cleaner production craft, pay attention to the green technology in environmental protection and resource development, and fundamentally control environmental pollution and ecological destruction.The second is that in according to repair of geological environment wholy and increasing regulation of coal mine area.Three are in coal mining process, by engineering technology to prevent collapse.Four is to improve the utilization of waste water recycling waste, will realize the maximum.This paper lists the our country's the six rules and 19 technical specifications which in order to implementation for mine geological environment protection and restoration of management promulgated in recent years. It expounded the mining of coal mine geological environment influence, and on the basis of investigation and study in heilongjiang province proposed coal mining of mine geological environment caused by the four harm, namely:One is the impact of groundwater system and destruction, including the phreatic water surface drops of water supply shortage, area structure, aquifer destruction, etc.Second is the soil pollution.Third, geological hazards, mainly landslides, ground subsidence and ground fissures.To develop mine geological environment protection and treatment are necessity and realistic significance.Based on abundant coal mines sample of geological environment protection and treatment work in heilongjiang hegang source. It detailed introduces the natural geographical conditions and mine mining, summarizes the current history of mining technology solutions. According to relevant technical requirements for the mine geological environment assessment. This paper predicte the status quo and comprehensive evaluation of predictive evaluation. The evaluation content include geological hazard, groundwater resource environment and the land resource and the geological landscape impact from three aspects.Assessment showed that the mine geological hazard is ground subsidence mainly for harm, serious influence degree, major in land resources to crack damage, and seasonal frozen non-dangerous thawing, common development, building area is not to cause serious damage, geological hazard, Water, groundwater quality evaluation area is good, have polluted mine production activities, surface and groundwater effect of land resources, geological and landscape of great influence, serious destruction. A mine construction project, the geological disasters may cause for potential unstable slopes of coal and gangue may cause certain conditions of gangue and small-scale slippery, rolling, geological hazard is small, easy recovery, The geologic for ground subsidence, ground fissures, geological disaster harm, risk bigger, The mining construction and production activities on the surface and groundwater environmental impact rang lighter, Land resources of land with geological landscapes.According to the mineral resources development plan, the mine geological environment problems types, distribution and its harmfulness of mine geology, environmental impact assessment results, mining area is divided into east mine geological environmentâ… key areas (southern) and western, the mine geological environment general control area (â…¡).Based on the formation of the appraisal conclusion , in order to protect and comprehensive mine environment the six restore tasks are proposed, the ultimate goal is that"protecting and recovering while and after producting".The rest of the protection and recovery in production activities in a timely manner after recvery. After 1 year's recovery of ground subsidence and ground fissures and geographical disaster land destroyed the relevant national standards.Main engineering measures are taken measures, backfill engineering geological hazards and monitoring and warning engineering treatment measures, and formulate the corresponding prevention, control and monitoring program.In order to improve the operability of programe, the recovery management funds for this project has been made a budget according to the national relatedrequirementa.After treatment the environmental and economic benefits and social benefits are analyzed, and puts forward the necessary conclusions and recommendations are put forward. |
