A Prototype Decision Making Tool of Coal Mine Planning Using System Dynamics Model

The decision on investment in mining, particularly coal mining project is a complex decision system. Because of coal mining systems has many variables connected, and respond to each other such as production rate planning, mine life, stripping ratio, cost and income of mining, etc. So, it is not easy to know in mining time scale with automatic calculation responding, when some value of variables in coal mine planning change, what will happen with others. Moreover, if a variable change or multiple variables change, may give the different results. Thus, the complex variable system like in coal mine planning, cannot be solved easily in the general way, for example, calculates cover all possibility result, or discovering the optimal solution in the site condition criteria.
