Research on the development path of mining green and circular based on system dynamic model

It’s difficult to grasp the development trend of the green and circular development of the mining industry with many influence factors.And the coordination between the major factors become the key to its realization.Mining green and circular development is regarded as a complex large system, including five subsystems, such as resources, economy, population, environment, science and technology.Combining the concept of green development with the “3R” principle of circular economy, with the help of system dynamics theory, which is good at solving the problem of nonlinear complex large system.Based on the fact of Lueyang county, the authors builded a system dynamics model of mining green and circular development, to explore optimal path for achieving county’s mining green and circular development.At last, through simulation, three typical paths are selected:natural development path Ⅰ, economic development path Ⅱ, green and circular coordination path Ⅲ, and then the simulated results of three typical path were analyzed.The results show that green and circular coordination path Ⅲ is the best path to achieve mining green and circular development.In the end, some suggestions based on the path are proposed, and hoping that could be helpful for the local mining development.
