Analysis of road conditions of operation of mining dump trucks in the Republic of Uzbekistan

Abstract

In the Republic of Uzbekistan, the mining industry is an integral part of the economy. It is also suitable for JSC NMMC to produce more than 105 tons of gold, more than 700 thousand tons of silver, etc. This article analyzes the road conditions of operation of quarries in the Republic of Uzbekistan. Analyses show that the road conditions of quarry operation are heavy, which is why large-sized tires of dump trucks do not give a guaranteed mileage. Based on the above, a statistical analysis of the mileage of oversized tires is given. This article provides an analysis of road conditions during the operation of special equipment on the example of the Muruntau quarry of the Republic of Uzbekistan. The infrastructure of operating conditions is investigated, the main components of which are road slopes and the condition of the road surface. In particular, the slopes are 15–20 % or more, and the surface quality is the strongest abrasive material – a mixture of ground rocks with metallized inclusions, which leads to intensive wear of the tire tread.
