Influence of tire temperature conditions on the capacity of quarry dump trucks operated in JSC "CC Kuzbassrazrezugol"

More than 50-60% of minerals in Russia and the CIS countries are mined an open-pit or mining quarry, as it is most economical productive. JSC "CC Kuzbassrazrezugol" ranks second terms total coal production among regions Russian Federation first Kuzbass. Quarry dump trucks main mode technological transport when transporting rock. An important task facing road to reduce cost transported products. The components costs include fuel, tires, maintenance repair, roads others. It possible tires by controlling life. Most often, thermal damage causes emergency decommissioning tires. maintain optimal temperature regime quarry truck with help operating modes such load capacity utilization factor speed, well conditions ambient longitudinal slope road. In turn, performance directly depends on modes. On one hand, growing speed increase productivity trucks, but at same time this increases reduces their reliability. This article proposes a methodology for determining maximum operated CC Kuzbassrazrezugol taking into account
