Abstract
When transporting overburden rocks in a cold season, the lower layer of materials freezes to working surfaces of transport equipment, and at long transportations – congeals under its own weight. As a result, up to 50 % of rock remains in the vehicle, while the unloaded part represents indiscreete frozen mass. It considerably complicates the process of unloading transport and leads to increased labor and financial expenses. A rational and effective remedy for these problems is transport equipment and bulk material processing with chemical agents of oil and petrochemical origin – mixtures of distillate and bottom frations obtained as a result of thermodestructive processes during petroleum feedstock manufacturing. The article presents data on the quality of distillates and residual products of oil recycling, which are used as initial components for producing preventive drugs, which are used to prevent sticking and freezing of overburden rocks during transportation and storage in the cold time of year, as well as drugs used for pit roads treatment in surface mining operations. Optimal component compositions of new petrochemicals are developed, and the physical and chemical properties of the received test samples have been studied.
