System Dynamics Simulation of Energy Saving and Emission Reduction in Coal Mining Area

This paper established a system dynamics model of energy saving and emission reduction in coal mining area, as well as conducted simulation of different development plans, based on the analysis of energy saving and emission reduction factor of coal production links, of the complex structure of energy saving and emission reduction system in coal mining area, and of the dynamic feed-back mechanism inside the system. Result shows that total investment, coal production investment, environmental protection investment and coal energy consumptions per ton play an important part in the energy saving and emission reduction system in coal mining area. By adding total investment and refining the proportion between coal production investment and environmental protection investment, as well as reducing coal energy consumptions per ton, harmonious development of economic and energy saving and emission reduction could be achieved.
