Specifically, the essence of the green low-carbon development is to innovate the traditional production mode on the premise of considering the environmental bearing capacity and the ecological environment capacity so as to realize the sustainable development of economy, society and environment. The irreversibility of coal resources and the irreversibility of environmental problems determine that the development of coal enterprises should be based on a long time, and a green development concept is always implemented in the life cycle of the coal enterprises, so that the adverse effects of coal mining activities on ecological environment and other resources are reduced or prevented as much as possible. Based on the development characteristics of the coal enterprises, the whole life cycle of the coal enterprises can be divided into four stages of planning and designing, building production, shutting down and exiting and transforming and upgrading. It is worth noting that although a certain progressive relation exists in time logic in four development stages of a whole life cycle of a coal enterprise, the stages are not completely separated, for example, in engineering practice, most of mining area planning design and construction production are synchronously and alternately developed; for some coal mine enterprises with strategic high eye level, the arrangement enterprises begin to carry out green transformation upgrading in the coal resource production stage, and the simultaneous planning, simultaneous construction and simultaneous production of the coal resources and non-coal industries are realized. And then, all evaluation indexes of the green development of the coal enterprises are obtained in a mode capable of being obtained from national coal industry development reports, then the obtained evaluation indexes are subjected to a shortest distance clustering method, each green development evaluation index of the coal enterprises is divided into the development stages of the coal enterprises with the nearest distance, a first-level index and a second-level index are divided at the next development stage, and the construction of a green development evaluation index system of the coal enterprises is completed.
According to the scheme, the green development of the coal enterprises is divided into four stages, namely planning design, construction and production, shutdown and exit, and transformation and upgrade stages.
The planning and designing stage comprises 4 primary indexes and 18 secondary indexes, and the primary evaluation indexes are coal resource green degree, a resource development planning scheme, an energy-saving and environment-friendly plan and enterprise standard management. 1) Green degree of coal resources. The green degree of the coal resource is comprehensively determined by resource occurrence conditions such as coal bed burial depth, coal bed stability, coal bed structure complexity, coal quality and the like, and the occurrence conditions of the coal resource have close relation with mine production capacity, mining mode, economic benefit and safe mining. Generally, the better the conditions for the formation of the coal bed, the higher the degree of greenness. 2) And (5) a resource development planning scheme. And compiling a green mining planning scheme, which comprises mining area division and roadway arrangement, main and auxiliary facility arrangement, resource development flow, green mine construction planning, a green mining technical scheme, a ground disaster treatment scheme, a mine gas extraction scheme and the like. 3) Energy-saving and environment-friendly plan. And formulating an ecological environment management planning scheme, which comprises ecological environment restoration plan, energy-saving and environment-friendly planning, tailing, waste rock, waste well water, associated resource comprehensive utilization measure planning and the like. If the planning file is provided and the planning scheme is reasonable and feasible, the index can be considered to meet the green development requirement. 4) And (5) enterprise standard management. Coal enterprises need to obtain a safety, environmental protection and quality certification system specified by national relevant standards and establish a green mine organization and a regulation system.
The construction and production stage comprises 6 primary indexes and 20 secondary indexes. The first-level evaluation indexes are safety, high efficiency, comprehensive utilization of resources, energy conservation, emission reduction, ecological environment protection, enterprise standard management and scientific and technological innovation. 1) Is safe and efficient.

And in the high-efficiency mining aspect, advanced production processes and equipment are recommended to improve the coal mining efficiency. 2) And (4) comprehensively utilizing resources. The comprehensive utilization of resources mainly refers to the comprehensive utilization of coal gangue, mine water and co-associated resources. 3) Energy conservation and emission reduction. The method is used for measuring energy consumption and waste discharge in the production process of coal resources, and comprehensive evaluation is generally carried out by using energy consumption, three-waste discharge coincidence rate and noise discharge of products in mine units. 4) And (4) ecological environment protection. The ecological environment protection in the construction and production stage is realized by stopping the waste rock field earthing greening, the subsidence area treatment rate and the subsidence stable land reclamation rate. 5) And (5) enterprise standard management. A green low-carbon propaganda and energy-saving environment-friendly training annual plan is formulated, and meanwhile, a reasonable and efficient green mine assessment mechanism needs to be established to guarantee that the green mine construction work is implemented according to the plan. 6) And (5) scientific and technological innovation.

The shutdown exit phase comprises 3 primary indexes and 8 secondary indexes. The first-level evaluation indexes include prevention and control of left-over disasters, social influences and sustainable development of mining areas. 1) And (5) preventing and controlling the left-behind disasters. The ecological geological environment of the mine area which is shut down and quit is high in vulnerability, and the left disasters are easy to occur. The incidence of the left-over disaster explains the safety and stability of geological environment and the feasibility of sustainable utilization of the shut-down exit mining area to a certain extent, and the lower the incidence of the left-over disaster is, the higher the greenness is. For coal mines, common left-behind disasters include ground surface collapse, mine water burst and coal bed methane cross flow disasters. 2) Social impact. Mine shut-down exits involve the placement of a large number of mine personnel and the disposal of liability. From the perspective of people oriented, the higher the personnel placement rate and the rate of handling the liabilities, the higher the green development level of the mine. 3) The mining area can be developed continuously. And (3) fully preparing for sustainable development of the mining area in the shutdown stage, wherein specific work comprises evaluation and exploration of underground resources on the ground, ecological environment restoration and landscape remodeling of the mining area and establishment of a green transformation scheme of the mining area.
The transformation and upgrading stage comprises 6 first-level indexes and 20 second-level indexes. The method is characterized in that the common transformation mode of the mining areas in China is to develop old mining areas into ecological parks, museums, industrial tourism or industrial landscape parks and the like, the 'green park evaluation index system' in China can be referred to for the evaluation of the green development level of the transformed mining area parks, and the primary evaluation indexes of the method comprise energy utilization, resource consumption and utilization, infrastructure greening, industrial greening, ecological environment greening and operation management greening. 1) And (4) energy utilization. The method encourages the park to develop and utilize new high-efficiency and energy-saving equipment, new materials, new technologies and new processes, and improves the use ratio of renewable energy resources and clean energy resources. 2) Resource consumption and utilization. Besides ensuring that the energy conservation and emission reduction of the park completely meet the relevant standards, the utilization rate of common resources such as solid wastes, reclaimed water, waste heat resources, waste gas resources and space resources also needs to be concerned, and the waste of a large amount of resources is avoided. 3) And (5) greening the infrastructure. The park green infrastructure comprises three aspects of sewage centralized treatment facilities, green buildings and green traffic. Regarding the sewage centralized treatment facility, the related standard is referred to for execution; for green buildings and green traffic, the larger the proportion is, the higher the green level of the park is represented. 4) The industry is green. The industrial greening mainly focuses on the ratio of the total value of the green industry and the high and new technology industry to the total value of the garden, the proportion of the modern service industry of the garden and the technological innovation and the intelligence degree thereof. 5) The ecological environment is green. The green degree of the ecological environment of the garden in the transformation and upgrading stage is determined by pollutants, greenhouse gas emission, garden greening coverage rate and ecological environment recovery standard reaching rate. 6) The operation management is green. The park should establish a green park standard system which is suitable for the industry chain and the leading industry, establish a park development plan which meets the national and local industry policy requirements, establish a green park information management platform and release related information periodically.
