The article presents the original practical results of experimental data of monitoring the conditions of mining haul roads using the on-board digital monitoring system installed on mining dump trucks. The efficiency of mining vehicles largely depends on the quality and operability of mining roads. Therefore, control of road conditions is an important opportunity in improving the efficiency of open-pit mining of mineral deposits. According to the results of the earlier studies, it was established that appropriate construction and maintenance of mining haul roads, allow to reduce total cost of road transport for individual cost items by 10–50 %. Possibility of improving efficiency of mining transport by timely detection of hidden defects of mining haul roads is considered in the study. The tasks were executed by setting up experimental studies, using GPS digital data, processing the results of experimental studies using methods of mathematical statistics, regression analysis and probability theory. The carried-out researches and the developed on their basis intellectual method of monitoring the condition of mining roads permit to detect degree of influence of operational factors of mining haul roads on efficiency of use of open pit mining dump trucks by means of information of on-board automated systems of dump trucks. The novelty of the work it consists in establishing the influence of the quality of mining haul roads on the level of dynamic loading of metal structures of dump trucks in the form of frame twisting, longitudinal or transverse bending, excessive fuel consumption, reduced speed, service life of tires, productivity, increase of maintenance and repair costs. Practical significance of the work it consists of use of the results of monitoring the condition of mining roads as pre-design materials and an informational base for development of reconstruction, overhaul, ongoing repair and maintenance projects for operated roads in the established manner.
