Promote the transformation of mining ecological civilization with "Mine green Development index"

The establishment of "mine green development index" is to serve the government's mining management function by setting up "necessary conditions" for mine development, so as to ensure green development from the source, which is also a beneficial supplement to the construction of green mines.

To establish the "mine green development index" system, we must use the method of "rule of law thinking" and "bottom line thinking", focus on keeping the red line and protecting the bottom line, reflect the government's macro management will, and reflect the national will of national asset management supervision of mountains, forests, fields, lakes and grasses. The "Mine green development index" system is the necessary technical support for government mining management and the necessary technical means to keep the bottom line of management. "Mine Green Development Index" can be released to the public in an annual manner, which has become the basis for the whole society to carry out mining development activities.

The establishment of the "mine green development index" system should take the value of raw ore as the economic attribute, the property of mine as the mining attribute, the property of mineral as the process attribute, the social development as the investment attribute, the environmental capacity as the guarantee attribute, and the recovery of the mine as the guarantee attribute, and form an evaluation system of "necessary conditions" for mine development that accurately selects the value of mine development and utilization. Support the government's management functions such as the establishment of mining rights. In this case, "economic attributes" are the benchmark, and other "attributes" are the correction parameters of the benchmark. On the premise of meeting the "necessary conditions" for mine development, enterprises and society are encouraged to participate in mine development activities through the licensing system, and the "sufficient conditions" for mine development and utilization are formulated and optimized by the main body of mining development in accordance with the principles of technology, capital, environment, market, management and other allocation, and organize the implementation of mine development plans.

The establishment of the "mine green development index" system is to prohibit low-value mining development activities and encourage high-value mining development activities through the evaluation of mine development value, so as to lay the material foundation for the realization of "green water and green mountains".

China Mining News: "Mine Green Development Index" as a new research and development direction of the mining industry, should follow what ideas and methods?

Hu Zesong: First, the establishment of "mine green development index" should be simple, scientific and operable. In line with the principles of fairness and openness, objective science, simple and pragmatic, highlight the solution of major contradictions, do not seek perfection blame, guide the establishment of "mine development index" impact factors and data collection, minimize the subjective judgment factors, improve the authority of government information release.

The "Mine Green Development Index" system includes the following impact factors:

- Raw ore value factor: the weighted composition of the value of the available minerals, which can be released regularly with reference to the international metal and non-affiliated markets;

-- Mining factors: taking stripping and mining ratio as the main parameters to determine the mining influence factors;

Mineral process factors: using process particle size and "fatal impurity" content as the main parameters to determine the mineral availability impact factors;

-- Mining investment factor: taking the GDP of mining area as the main parameter, determining the impact factor of mine investment efficiency;

-- Environmental bearing factors: The average annual rainfall is used as the main parameter to determine the environmental bearing factors of mines;

- Mine recovery factor: The ratio of the amount of available minerals to the amount of waste generated by processing is the main parameter to determine the impact factor of mine recovery.

The above "impact factor" data is mainly collected from trading market announcements, special government announcements, national or industry technical standards and specific mine technical reports. Through the evaluation model of the correlation and tightness of the "impact factors", the "mine green development index" is evaluated comprehensively.

Second, the research idea should be based on the existing mine geological report, development and utilization plan, environmental assessment and safety assessment report, and the research should be carried out according to the "six factors" and the corresponding impact. Study the grade division of each impact factor and the weight ratio among the impact factors, assist computer network technology, establish the impact factor evaluation model, and form a simple, practical, operable and guiding "mine green development index" system.
