In an open-pit mine located in northern Chile, the key performance indicator TKPH (Ton-Kilometers per Hour) for mining trucks has been a constant challenge due to premature tire wear caused by excessive speeds on certain routes of the operation. To address this issue, this study aims to analyze different speed restriction scenarios, which were evaluated using discrete event simulation with the software Orchestra, to identify an optimal scenario that reduces TKPH without affecting production. The work involved simulating the traffic flow of mining trucks over a day in the mine and changing certain variables to represent different speed restriction scenarios. Multiple scenarios were evaluated, where the ideal scenario was the one that imposed a 30 km/h speed limit in the busiest areas. The simulation results indicated that this scenario succeeded in reducing the trucks' TKPH and kept almost 90% of the cycles below the value suggested by the tire supplier. This speed restriction was selected for its potential to minimize tire wear without significantly compromising productivity. Furthermore, the following study demonstrates that discrete event simulation is a valuable tool for informed decision making in the optimization of mining operations, since the operation is a complex system, the simulations allow for greater representativeness.
