HAUL ROAD CONDITION IMPACT ON TIRE LIFE OF MINING DUMP TRUCK.

摘要: Purpose. Offroad tires (OTR) for mining and earthmoving applications which are specially developed for extreme mine site conditions can take 10–20% of transportation costs. Up to 15% of OTR content is natural rubber produced from a rubber tree known as hevea brasiliensis. A significant number of OTR fail before the target life built in by tire manufacturers. This has certain negative impacts on the environment and wildlife due to deforestation effect. Thus, the purpose of the work is to increase the du rability or, in the terminology of the operators, the “mileage” of the OTR. Methodology. The current study represents analyses of new modern digital technology for monitoring the mining haul road condition within a site study on Bogatyr Komir coal mine in North Kazakhstan. The influence of operating conditions was con trolled, ie road quality, temperature conditions, tire pressure, and other parameters on tire life. Findings. The results show the effectiveness of digital technologies and the possibility of extending the life of tires by following the recommendations of the system in a timely manner. As a result of the analysis of temperature regimes and pressure in tires, especially in summer conditions, recommendations for rational operating conditions were determined, which makes it possible to increase the durability of tires.Originality. Modern operational digital methodology for monitoring open pit mines road condition defines ton kilometer per hour (TKPH) indicator per every trip, which provides ontime information for road design and maintenance. Practical value. Growing worldwide demand is driving the development of the mining industry. In the future …
