Abstract: In the parameters optimization of surface mining process, It is necessary to construct a suitable model for solving the problem by using the conventional optimization method. However, there are often difficulties in modeling and solving problems in engineering problems. Aiming at this, the simulation method of process parameters is proposed, The core idea is " to determine the logic flow of the system - to extract the underlying drive events - to determine the simulation type and clock simulation method - to build the system state of the quantitative model - simplify control logic - build drive event quantization model - replay system ". This paper studies the application of the overcast stripping technology in Heidaigou surface mine, the logic flow of the system is decomposed into three layers, the basic operation of the equipment is the driving event of the system; the center of gravity circle projection method is proposed to simplify the system control logic, and the system storage state model based on the three-dimensional model is constructed; The discrete event system modeling is selected and the simulation process is advanced by the event step method. The simulation results show that the system efficiency is maximized when the bench height is 13m, and the error is minimized when the simulation correction coefficient is 0.94.
