8 concepts about green mines

■ Green Mining

Compared with the traditional "black or brown mining", green mining is the product of the third technological revolution and the era of ecological civilization.

Green mining means that under the norms of ecological civilization, the concept of green development runs through all links of mining development such as mineral resources exploration, mining, processing, management and land reclamation in mining areas.

With resource conservation and environmental protection as the basic requirements, green planning, green technology, green production, green policy, green action, green management as the strategic framework;

Scientific mining methods, efficient utilization of resources, standardized enterprise management, environmental protection of production processes, ecological mining environment, mining order harmony into the implementation of the path to achieve economic benefits, social benefits, ecological benefits of the sustainable development of mining.

The connotation of green mining is mainly manifested in two aspects:

On the one hand, the resources themselves, that is, reasonable development, full use;

On the other hand, there are environmental problems caused by mining, that is, to minimize the impact of mineral resources exploitation on the ecological environment. Therefore, green mining is not a simple denial of traditional mining, but the adjustment, transformation, transcendence and innovation of traditional mining.

■ Mine ecological restoration

Mine ecological restoration is to use the principles and methods of ecological engineering or ecological balance and material circulation to improve, improve, restore and reproduce the survival and development state of mining organisms (groups) in polluted, damaged and stressed environments, also known as mine ecosystem restoration.

The emphasis is on the overall reconstruction and improvement of the damaged mine ecosystem by human beings, the necessary conditions for its occurrence, the further improvement and comprehensive improvement of the nature by human beings, and the partial return to the structure and function of the mine ecosystem before the disturbance.

■ Mine environmental restoration

Mine environmental restoration is the restoration of the polluted mine environment, that is, the use of engineering and technical means, physical and chemical means to reduce the concentration of pollutants in the polluted mine environment to the state before pollution, including environmental biological restoration and environmental ecological restoration two levels.

Environmental bioremediation is only the use of biological life metabolic activities to degrade the pollutants in the polluted mine environment, and make them non-toxic and harmless.

Environmental ecological restoration is to restore the mine polluted environment through the self-organization and self-regulation ability of the ecosystem, and to degrade the mine pollutants by selecting special plants and microorganisms and artificially constructing the ecosystem. Mine environmental restoration is an intrinsic part of mine ecological restoration.

■ Mine ecological restoration

Mine ecological restoration means that the disturbed and damaged mine ecosystem (soil, plants and wildlife, etc.) can be restored to the natural state close to its disturbed state by using the ecosystem succession and self-recovery ability under the assisted control of human beings.

It is a full sense of restoration, requiring limited intervention, while emphasizing the return to the original state from the level of natural science and engineering technology, is required to fully return to the structure and function of the mine ecosystem before the disturbance.

It includes the process of returning to the original state, restoring and managing the integrity of the native ecosystem of the mine.

It also includes the perfection and health of the critical range of changes in mine biodiversity, ecological structures and processes, regional and historical content, and sustainable social practices, but does not include the meaning of restoration.

■ Mine ecological reconstruction

The ecological reconstruction of mine refers to the re-establishment and construction of the ecological environment of mine by taking the original ecological environment of mine or the surrounding ecological environment as the main reference.

It includes re-establishing the original ecosystem without improving and trimming it, or abandoning the original ecosystem and establishing a new ecological environment, which must be better than the original ecological system and more suitable for mine production, human survival and sustainable development.

In short, green mine construction is a community of mining environment, resource development mode, comprehensive utilization of resources, energy saving and emission reduction, scientific and technological innovation and digitization (intelligent) mine, enterprise management and corporate image, which is not only indispensable, but also adopts the "double standard" system in the evaluation process, that is, the first level index and the total index of the evaluation index reach the standard at the same time, which is the green mine construction reaches the standard.
