Improving the approach to the organization of technical repairs of dump trucks using remote monitoring systems of their nodes

Given the critically important role of haul trucks in the overall mineral extraction process chain, the suspension system — the component with the highest failure frequency — was selected as the research object. The authors propose a method for quantitatively assessing a group of parameters of a technological transportation route due to challenging mining operating conditions. Using data from two mining enterprises over a three-year period, dependence was established between the reduction in the service life of dump truck suspensions and each of the identified factors in the route parameter groups. The assessment was carried out using data from remote monitoring systems installed on the vehicles. Based on the derived dependence, a criterion for optimizing the overhaul interval of haul truck suspensions was developed, incorporating a set of planning and economic factors. This criterion allows decisions to be made on the advisability of implementing measures aimed at achieving a target reliability level for the suspension system within the framework of the maintenance strategy adopted by mining enterprises, which combines scheduled and emergency repairs of machine components and assemblies. Using the proposed criterion, an optimal ratio between grading equipment and haulage equipment was determined when forming the vehicle fleet. Furthermore, an algorithm for determining a rational overhaul interval for haul truck suspensions was developed based on this criterion. Implementation of the algorithm at the mining enterprises under study has significantly reduced both the duration of unplanned downtime caused by suspension failures and the time required for repair activities.
