In the early stages of economic development, mining development methods were simple and extensive, and insufficient attention was paid to environmental pollution control. After the establishment of the Ministry of Land and Resources in 1998, the national level supported the restoration and management of the geological environment of mines. The focus of mine governance is fund raising. In 2006, the Ministry of Finance, the Ministry of Land and Resources and the State Environmental Protection Administration jointly issued the "Guiding Opinions on Gradually Establishing Responsibility Mechanisms for Mine Environmental Governance and Ecological Restoration", which proposed the basic principles of a deposit system for mine geological environment restoration and governance. ideas. The difficulty of environmental management in mines is the low level of restoration technology and the relative lack of professionals.

In order to solve outstanding problems existing in the process of ecological restoration of mines, national and local policies have been issued one after another, such as the "Notice on Carrying out National Historical Mine Inspection Work", "Opinions on Exploring the Use of Market-oriented Methods to Promote Mine Ecological Restoration", "On Supporting Mine Ecological Restoration" Notice on Carrying out Ecological Restoration Demonstration Project of Historically Abandoned Mines", "Shandong Province Mine Ecological Restoration Implementation and Management Measures", "Hebei Province Mine Comprehensive Management Action Plan", "Decision on Strengthening Mineral Development Management and Control to Protect the Ecological Environment", etc. According to the overall framework of ecological civilization construction, following the principles of government leadership and market operation, through conceptual changes and policy guidance, social capital is encouraged to participate in the ecological restoration management of mines, and a systematic, scientific and standardized governance model is adopted to improve the ecological restoration capabilities of mines and achieve ecological restoration goals.

Abandoned mines left over from history destroy the natural landscape and present potential risks of geological disasters such as landslides and collapses. Environmental pollution caused by mining reduces local biological populations, so ecological restoration and management of mines is imperative. There are many deficiencies in the main aspects of the restoration system, such as restoration mechanisms, restoration funds, restoration models, restoration projects, restoration technologies, etc., resulting in low quality and slow restoration. Therefore, the problems of ecological restoration in mines are summarized, and targeted governance measures and suggestions are put forward. , which is conducive to forming a complete mine restoration system and accelerating the progress of mine restoration.

Based on the differences in mine types and mining methods under different natural conditions, the state formulates standardized and serialized restoration standards and governance technical specifications to improve operability, enforce enforcement, improve the level of mine governance, and reduce the number of mines that do not meet governance standards. Strengthen the basic theoretical research on ecological restoration of mines, improve the level of scientific and technological support, and reduce application costs. At present, ecological restoration technologies are mainly physical restoration, chemical restoration, biological restoration, joint restoration and other methods. Single restoration technology often cannot meet the needs of mine ecological restoration. Joint restoration technology will be increasingly used in mine restoration. On the premise of ensuring geological environment management and eliminating major pollution such as heavy metals, mine restoration improves vegetation survival rate, achieves biodiversity reconstruction and regional ecological function restoration.

Desen Environment focuses on chemical remediation methods and uses soil washing technology to recently develop a Desen washing truck. It is my country's first mobile washing truck, filling a gap in the domestic and foreign markets and playing a landmark role in the soil remediation industry. The modular integrated design of Desen's washing and restoration truck is fast to install, flexible and convenient, and successfully solves the problems of steep mine terrain, large equipment footprint, and inconvenient movement. This mobile soil washing equipment can also integrate biological, chemical, physical and other comprehensive remediation technologies, greatly improving the remediation efficiency and saving a lot of costs.
