Simulation of HD 325-6 Dump truck Tires Performance of Angoran Lead and Zinc Mine

The mining industry is one of the most influential industries in the economy of any country. Today, mining companies are attempting to reduce the costs of mining operations by using different sciences. Tires are one of the expensive and dangerous components of mining dump trucks, and because they are used in certain conditions, they are always prone to premature failure, but this can be prevented with methods. Dump truck load and speed are among the most effective and controllable operating parameters in improving tire life performance. The simultaneous effect of these two variables can be checked in the form of ton-kilometer per hour index and through its analysis, tire life can be improved. The purpose of this research is to manage the ton-kilometer per hour index, investigate its effect on the performance of the HD 325-6 dump truck tires in the Angoran lead and zinc mining complex. Due to the uncertainty of operational parameters, Monte Carlo simulation using MATLAB software has been used to control the failure of tires of the studied dump truck. This research was conducted by collecting and analyzing operational data in 10 work cycles in Sep. 2023. The results of the investigations show that there is a 21.6% probability of passing the TKPH limit of Tianli TUE400 tire. Therefore, it is suggested using tires with TKPH greater than 170 for the mentioned dump truck. In addition, the life of the tires is less than their nominal life, which can be caused by the poor conditions of the ramps.
