The simulation of mine solid waste generation in Panzhihua City based on system dynamics

In recent years, the scale of steel production in Panzhihua City - an important mining centre for black, non-ferrous metal in China - has rapidly doubled in response to the tremendous demand for industrial development, placing tremendous pressure on the environment. This paper simulates and predicts the discharge, treatment and reutilisation of solid waste in the iron and steel industry by constructing a system dynamics model. The results show that the model can be applied effectively. The solid waste volume has a tendency to rapidly increase and the stripping ratio shows a decreasing trend. The reutilised volume of tailings increases substantially over time and the reutilised ratio in the environment scenario is higher than that in the current scenario.
