Green mine creation standards and evaluation indicators

First, the meaning of green mines

Green mines are a new way of thinking about mineral resources management and mining development in the new situation. The construction of green mines is the only way to promote the economic progress of the mining industry. The rationale of “green mines” meets the development requirements of the 21st century, and it is more in line with the inherent requirements of building a harmonious society with the scientific development concept of “people-oriented, sustainable development”.

The green mine aims to protect the ecological environment, reduce resource consumption, and pursue a recyclable economy. The concept and practice of green ecology are embedded in the whole process of mineral resources development and utilization (mine exploration, planning and design, mine development, closed pit design). It embodies the respect for the natural original ecology, the cherishment of mineral resources, and the protection and reconstruction of the landscape ecology.

Green mine construction is a complex system engineering. It represents the overall level of development and utilization of mineral resources in a region and the potential for sustainable development. It focuses on scientific, low-cost and efficient development and utilization of mineral resources, and minimizes the consumption of resource reserves, reduces mining costs, and achieves the best resource efficiency. Turn.

Second, the construction requirements of green mines

(1) Green mines must set up and organize production according to law

The construction of green mines must be based on the environmental impact assessment method and the mineral resources law in French, conduct environmental impact assessment and comprehensive assessment of safety status, have local soil and water conservation measures (plans), obtain mining rights, mine safety production licenses, forest trees according to law. cutting license, permit the use of explosives and other related licenses, the establishment of the management system in accordance with law, management and organization of production according to the law, pay taxes according to the law of governance and gold reserves, to ensure safety in production.

(2) Green mines must rationally develop and utilize mineral resources in accordance with the principles of science, low consumption and high efficiency.

According to the principle of science, low consumption and high efficiency, the rational development and utilization of mineral resources is its basic premise. For the exploitation of mineral resources, scientific and rational planning and design must be carried out according to the resource status, demand and technical level, and the mining methods and technical equipment must be correctly selected. Secondly, the recovery rate and utilization rate of resources should be improved to minimize the consumption of resource reserves. Third, we must reduce the cost of mining and comprehensively utilize all kinds of resources (common, associated mines and abandoned resources) to maximize the benefits of limited resources.

(3) Green mines must meet the requirements of natural ecology and environmental protection.

The construction of green mines is a management practice based on solving environmental problems. Mining enterprises should incorporate environmental protection into their business philosophy, adhere to the principle of protection, create a pollution-free, waste-free, waste-free production system, reduce damage to the ecological environment and restore the ecological environment in a timely manner, in design, mining, transportation, etc. The process promotes comprehensive “greening” and does not create new ecological problems.

(4) Green mines must take the sustainable development of resources and the economic cycle as the development direction.

Continuously reduce ore grade expansion of reserves and exploration of new resources, extend mine service life, early new industry replacement and renewal, revitalize mines, study ecological restoration and reclamation techniques of mine closed pits, and develop mine closure planning and follow-up Land use and monitoring program (plan), set the direction of land use early, and reflect this directional requirement in the side-by-side remediation.

2. Renovate and introduce mining technology, select the construction period and mode that is conducive to ecological protection. Open pit mining operations should be carried out in accordance with top-down and horizontal steps. Underground mining should be carried out in accordance with relevant technical specifications. Mechanization and modernization of mining operations high.

3. Improve the supporting facilities of the mining area, realize the dust-free operation in the whole process of production (perforation, blasting, mining, transportation, stockpiling and slag discharge), reduce the mining ore, reduce mining and stripping, and minimize the occupation of forest land and soil erosion. .

(4) Clean production (cleaning of mining operations)

And less pollution.

(5) Standardized management (standardization of mine management)

Fourth, the green mine creation assessment indicators

For the above-mentioned green mine creation standards, establish a corresponding evaluation index system (Figure 1), and give the corresponding evaluation index values ​​(Table 1).

Table 1 Green to mine assessment criteria

V. Implementation recommendations for the creation of green mines

(1) Adhere to standards and standard procedures

To establish green mines, we must adhere to standards, strengthen supervision and inspection, and standardize working procedures. For the creation of a green mine, a plan for the creation of a work should be formulated. The qualification unit should prepare a “Green Mine Creation Plan”. After the mine enterprise implements the green mine creation work according to the program requirements, it conducts a self-examination and self-assessment against the standard and submits it to the local land and resources authority. declare. After the land and resources department organizes relevant experts to pass the examination and acceptance, it will be reported to the local government for approval, and the local government will issue a green mine honor certificate to enjoy the green mine preferential policy; the green mine will implement an annual review system, such as annual review failure or major violation of laws and regulations. Behavior, revocation of green mine resources, suspension of production and rectification until closure.

(2) Clarify policies and strengthen support

Establish a green mine incentive mechanism, included in the pilot green mining enterprises, can enjoy preferential policies after obtaining green mine qualifications. For example, if the mineral resources reserves and ecological environment carrying capacity of the mining area permit, the mining scale should be appropriately increased, but it must be consistent with the requirements of green mine construction; when the green mining enterprises re-grant the mining rights in the original mining area, the increase in mining scale should not exceed In the case of a certain proportion of the original mining scale, the mineral resources development and utilization plan, soil and water conservation plan and environmental impact assessment report may not be re-formed; the mine environmental management reserve fund handed over by the green mining enterprise may be returned in advance in annual; Among the mining rights transfer fees, sewage charges, soil erosion fees, etc., the green mining enterprises are subsidized in proportion.

Conclusion

Through the research on green mine construction standards and evaluation indicators, the green mine construction procedures will be more clear, and the green mine construction assessment indicators will be more operable, which is conducive to the rational development and utilization of mineral resources and sustainable development. Although the research used in this paper has certain limitations, the formulation of construction standards is not perfect, and the basis for determining the value of evaluation indicators is not sufficient, but in the current situation of ecological construction, this useful exploration is of great significance. With the rise of the nationwide green mine construction, construction standards and evaluation indicators will be more perfect.
