Research on Factors of Coal Production and Causality Model Based on Sustainable Development

摘要

This paper analyzes interaction and feedback relationship between coal production sustainable development and various factors with system dynamic method. It establishes a causality model and analyzes feedback loops in the model. Finally, it obtains the relationship between coal production capacity and coal output level, namely the greater coal production capacity is, the higher coal production capacity and the coal output level are. However, resource consumption level increases with the increase of coal output level, thus further lowers resource carrying capacity.
