| Popis: | Relevance. The need to optimize the parameters of mining systems at the level of modern scientific and methodological capabilities, which leads to development of a methodological approach to their description taking into account transients. When optimizing the life cycle of quarry transport systems, mainly structural transients should be taken into account. At the level of its individual elements or optimization of quarry transport systems during their operation, special attention should be paid to parametric transients. Aim. To study the capabilities of the software "Quarry Transport System"; to develop approaches to assessing the impact of road factors on performance of quarry vehicles by simulation; to study the regularity of the influence of restrictions associated with the mutual influence of dump trucks on the rhythm of traffic on auto roads; to study the impact of road factors on the performance of dump trucks. Objects. Quarry with a depth of 380 m with a capacity of 125 million tons/year, with a fleet of dump trucks in the amount of 88 units. Dump trucks have a lifting capacity of 136–220 tons, excavators with a bucket capacity of 15–35 m3. Methods. Computer simulation of quarry transport system functioning; the computer program "Quarry Transport System" developed at the Institute of Mining of the Ural Branch of the Russian Academy of Sciences. Results. The "Quarry Transport System" software allows solving specific problems in the field of career transport, including those related to the assessment of the impact of road factors on technical and economic indicators of career vehicles. The authors have developed the approaches to assessing the impact of road factors on performance of career vehicles. They established the regularity of the influence of restrictions associated with the mutual influence of dump trucks on the rhythm of traffic on auto roads and the influence of road factors on performance of dump trucks. |
