How to do mine ecological restoration?

Thirdly, the construction of mine environment and ecological restoration information system should be carried out. Plan a unified system architecture, build a national mining geological environment data center around different business fields of mine geological environment, realize the information, integration, networking and intelligence of investigation, monitoring, management and related businesses, and support the ecological protection and restoration of mines; Improve the data collection and dynamic update functions of mine environmental investigation, monitoring and ecological restoration, and strengthen the functions of statistical inquiry, comprehensive analysis, decision support, assistance management and information release; On the basis of summarizing and analyzing the results of the annual national geological environment survey, monitoring results, statistical report data and ecological restoration results, the annual situation analysis report of national ecological protection and restoration of mines was prepared, which mainly included the analysis of the dynamic change trend of the national environmental problems of mines, the analysis of the leading factors of mine environmental change, the situation of ecological restoration of mines and the next countermeasures and suggestions.

Fourth, carry out research on the construction of mine ecological restoration policies and regulations system. Research and put forward the legal provisions on supplementing mine environmental management and ecological restoration in the revision process of the Mineral Resources Law, research on the compensation system for mine ecological restoration protection, research on the social capital investment system for mine ecological restoration, and research on the construction of the mine ecological restoration fund system.

Ecological restoration in mines should be implemented in different areas

The ecological restoration work of mine in China insists on systematic design, overall promotion and step by step restoration; Ensure safety, restore ecology and take into account the landscape; Focus on key areas, adapt to local conditions, and implement policies in different categories; Based on the principle of natural restoration and artificial restoration, the ecological restoration potential of mines is assessed and the direction of ecological restoration is determined according to the geographical location, climatic conditions, ecological region, geological background, social and economic conditions, major ecological problems and other factors of the mining area. At the same time, all kinds of mines with different scales, different mineral species and different mining methods are targeted. Different ecological restoration techniques were adopted.

According to the distribution of mineral resources in China, the status of mine development, the division of main metallogenic zones and the national topography, geomorphology and geological conditions, combined with the type and scale of mining ecological environment problems caused by the development of different types of mineral resources, the geological environment Monitoring Institute of the China Geological Survey has divided 23 mineral resource development zones with obvious regional and mineral characteristics across the country. According to the current situation and development trend of the ecological environment problems in mines, the short-term and long-term management areas are proposed on the basis of the national mineral resources development zoning. The recent management areas reflect the urgency and necessity of management, according to the "key mining geological environment management areas (524)" determined in the National Mineral Resources Plan (2016-2020), combined with the surrounding terrain and geomorphic conditions, formation lithology and mining location; The long-term management area reflects the continuity of the management work, based on the concentrated mining area of the geological environment of the mine, according to the comprehensive delineation of the distribution location and characteristics of the mine.

Four modes escort mine ecological restoration

To carry out targeted mine ecological restoration projects for different kinds of mines, and combined with regional characteristics such as social economy, natural landform landscape, cultural and cultural background, the geological environment Monitoring Institute of the China Geological Survey summarized four types of mine ecological restoration models:

-- Combined with the construction of mining park, etc., to build a city tourism brand. After years of mining, Huangshi Daye Iron Mine in Hubei Province has formed an open-pit 2,400 meters long, 900 meters wide and 444 meters deep, with more than 300 million tons of waste rock covering an area of 400 hectares. Through mining geological environment management and ecological restoration, the first national mining park with an area of more than 2,300 hectares has been built, which has greatly improved the urban appearance and brought good social, environmental and economic benefits to the local area.
