A large number of technical standards have been introduced, and two major contradictions in the ecological restoration of mines are prominent.

[ Industry News of Chemical Machinery and Equipment Network ] Not long ago, the central ecological and environmental protection inspector just reported a number of ecological problems, and the problems of insufficient attention to ecological and environmental protection in mine construction, weak supervision, and lag in some governance and restoration work were mentioned again
.
Looking at the typical cases reported in each round, the ecological restoration of mines has become a "regular visitor".
When will the "scar on the earth" be completely healed?
 

You must first understand where the crux is
.

 

First of all, the extensive mining of mines in China has left a lot of historical problems, that is to say, there are many "debts", and new accounts must be superimposed
.
It is said that the account needs to be calculated in a lump sum.
Even if many places have begun to carry out the measures of "whoever mines, who will govern" and "governance while mining", it cannot be solved overnight
.

 

　　Secondly, following what I just said, China has chosen a two-pronged approach to the ecological environment of mines, that is, while focusing on the ecological restoration of abandoned mines, it requires mine mining to carry out green mine construction from the very beginning, that is, no new accounts will be added
.
This not only requires a clearer awareness of transformation, but also requires stronger supervision and more professional solutions as support
.

 

　　Furthermore, the so-called professional solution involves the technical threshold of mine ecological problems, which is also the key crux
.
For example, for mine ecological restoration, you need qualifications - Grade A qualification for geological disaster risk assessment, Grade A survey unit for geological disaster control engineering, Grade A design unit for geological disaster control project, Grade A construction unit for geological disaster control project, etc.
; For green mine construction, you need a professional team and targeted solutions
.

 

　　Finally, the market needs differentiated solutions, and the industry needs a unified standard specification
.
In recent years, it has become clearer how to carry out ecological restoration of mines and how to build green mines
.

 

　　On April 18, the Ministry of Natural Resources issued "Technical Specifications for Mine Ecological Restoration Part 1: General Rules" (draft for approval), "Technical Specifications for Mine Ecological Restoration Part 2: Coal Mine" (draft for approval), "Mine Ecological Restoration" Technical Specifications Part 4: Building Materials Mines (draft for approval), "Technical Specifications for Ecological Restoration of Mine Part 5: Chemical Mines" (draft for approval), "Technical Specifications for Ecological Restoration of Mine Part 6: Rare Earth Mines" (draft for approval), "Technical Specifications for Mine Ecological Restoration Part 7: Oil and Gas Mines" (draft for approval), 7 consecutive technical specifications cover a variety of application scenarios
.

 

　　In addition, Inner Mongolia's "Technical Specifications for Ecological Restoration of Open-pit Mine Abandoned Land in Grassland Areas" (DB15/T 2378-2021), Jiangsu "Technical Regulations for Mine Ecological Restoration Engineering" series standards (DB32/T 4077.
X-2021), Anhui "Underground Mining" Green Mine Construction Requirements for Metal Mine (DB34/T 3922-2021), Shaanxi "Technical Specifications for Mine Geological Environment Management and Restoration" (DB61/T 1455-2021), Gansu "Green Mine Construction Specifications" series (DB62/T 4284.
X -2021), Hunan "Technical Regulations for Ecological Restoration of Mine Slopes" (DB43/T 2057-2021) and other local standards have laid the foundation for the standardization of mine ecological environmental protection
.

 

　　The Environmental Planning Institute of the Ministry of Ecology and Environment has sorted out the content related to mine environmental pollution prevention and ecological restoration in the provincial-level ecological environmental protection "14th Five-Year Plan" issued by 26 provinces (cities, districts), and its importance can be summarized
.

 

　　For example, Hubei proposed to comprehensively promote the pilot construction of ecological protection and restoration projects for mountains, rivers, forests, fields, lakes and grasslands in the Three Gorges region of the Yangtze River; Hunan proposed to carry out risk control and pollution control for water inflows from coal mines and non-coal mines that have been closed and withdrawn from the province; Sichuan proposed to comprehensively promote the Anning River Basin.
The ecological restoration project of abandoned mines left in history in key areas such as Shaanxi proposed to speed up the construction of green mines in Shenfu, Yushen, Huangling, Weibei, Binchang and other concentrated mining areas of mineral resources; Chongqing proposed that by 2025, the completion of historical and The area of ​​ecological restoration of mines is 24.
5 square kilometers; Fujian proposes to explore and implement a new model of ecological restoration of abandoned mines of "ecological restoration + utilization of waste resources + industrial integration".
.
.

 

　　At the beginning of 2022, the Ministry of Finance and Natural Resources also issued a notice to support the demonstration project of ecological restoration of abandoned mines left in history
.
Each province (autonomous region, municipality directly under the Central Government, Xinjiang Production and Construction Corps) shall apply for no more than 2 projects, the total investment of each project shall not be less than 500 million yuan, and the implementation period is 3 years
.

 

　　During the "14th Five-Year Plan" period, the market may pay more attention to these two contradictions
.

 

　　1.
Pollution reduction and carbon reduction
 

　　In the context of the "dual carbon" goal, mine ecological restoration and green mine construction also cannot jump out of the circle of pollution reduction and carbon reduction
.
Focusing on carbon reduction, pollution reduction, ecological restoration, and resource recycling, adhering to the priority of conservation, strengthening the "double carbon" constraint, and coordinating the ecological construction of abandoned mines and rural revitalization will all become links that cannot be ignored
.

 

　　2.
Heavy metal pollution
 

　　Whenever heavy metal pollution is involved, whether it is wastewater, waste residue or soil, or the mines mentioned now are more difficult and complicated
.
Of course, this is also proportional to its urgency
.
The industry believes that the development of heavy metal minerals has the characteristics of complex pollution causes, diverse types of pollution, sensitive ecological environment impact, and high demand for economical and applicable technologies.
Therefore, the difficulty of restoration has increased exponentially, and scientific, effective and applicable solutions are also needed
.
