Computer simulation and control of the mine locomotive system

Abstract

The existing technology in the fields of monitoring instrumentation and remote control equips the mining industry with a powerful tool for optimization of underground haulage systems. Transport automation and computerization increases the system's dependability and safety factor and decreases the transport expenditure. Simulation of a computer controlled mine locomotive system was performed to determine the status of the train in the system. The input/output variables were: detection of the train location, direction of movement, weight measurement of a mine car at a designated station, and light signals indicating the necessary road clearance for locomotive transport. A computer program was developed to provide for monitoring and control of the status of the train. Draw-bar pull test was performed for the locomotive as part of the locomotive resistance characteristic determining the coefficient of adhesion between wheels and steel rails.
