Three-dimensional ecological model of coal exploitation and utilization——Constructing “1+4” green and sustainable development ecology in Northern Shaanxi mining area

The mining,processing and transformation of coal resource based on the development of social ecology will eventually are transformed into social demands.The entire chain of activities is ecological which will determine the level of green and total factor productivity in coal mining and the future of coal resource utilization.Using a system engineering methodology,this paper studied the relationship among coal mining,coal resource utilization and the construction of ecological civilization.The development of primary,secondary and tertiary industries related to coal industry should be hierarchical,multi-dimensional and ecological.The three-dimensional ecological model in the coal mining process was proposed.The key elements,logical relations and construction methods of natural environment ecology,industrial ecology and social network ecology in the three-dimensional ecological system of coal mining were established respectively,and the “connotation,approach,goal and measures” in three-dimensional ecological system of coal mining was identified.The coal mining in the three-dimensional system solves the problem of “safe,efficient and clean” coal extraction.The natural environment ecology solves the problem of “symbiosis and coordination” between mining and environment.The ecological solution to the problem of “efficient and clean utilization” of coal in the industrial chain is the problem of maximizing the value of coal resource.The social network ecology is to solve the problem of “coal depletion and low carbon”.The three-dimensional ecological model of coal resource development and utilization has changed the positioning and function of the single ecology of the business subject and the single-line ecology of the industry or department,forming a step forward from the single subject and the single-line ecology of the industry to the three-dimensional networked ecological system.The three-dimensional ecological model breaks the limitations of existing models.It is no longer environmental protection and individual optimization,but a comprehensive ecology of all parties concerned.It is a coordinated and shared mechanism,a sustainable mechanism,an efficiency reform,and an ecosystem that is improved and developed by improving total factor productivity.On this basis of “1+4” green sustainable three-dimensional ecological construction in the northern Shaanxi mining area,this paper analyzed the role of three-dimensional ecological system construction in the coal mining process,and provided some new theories and methods for the green sustainable development of mines.
