Abstract. The purpose of the publication is to determine the feasibility of using different types of dump trucks in non-metallic quarries, considering the transport distances, trip duration, and productivity when transporting rock mass from the mines to the surface. To achieve this goal, the following research methods were used: analysis of modern quarry transport, analytical - to establish the parameters of the trip duration and dump truck productivity, graphical - to find the optimal type of dump truck, operational monitoring - to establish the time parameters of mining equipment operation. A review of the modern usage of dump trucks in the development of non-metallic quarries is carried out, which allowed us to distinguish dump trucks with a 4×2 wheel formula, articulated and tracked. An analysis of vehicle operation in different conditions was carried out. This made it possible to justify the parameters of vehicle operation and identify the factors affecting the performance of dump trucks. The results of the study are the determination of the dependence of the length of the route and the duration of the dump truck trip on the depth of the non-metallic mine pit face, as well as the productivity of the relevant machines. For crawler dump trucks, the parameters of dump truck operation and the formula for determining the approach time to the face for loading with rock mass and unloading at the appropriate site were established. The received dependence of the dump truck's approach allows us to determine the productivity of the crawler machine, taking into account the use of a full-rotating platform (the cab and body are on a single rotating base), which eliminates operations related to manoeuvring on the work site and increases the productivity of such machines. The research showed that transporting raw materials from the quarry using tracked dump trucks, thanks to the shorter transport distance, requires almost 40% less transport work (tonne-kilometres) than when using wheeled quarry dump trucks. The length of the route when using transport vehicles was determined, considering the increase in the road gradient for crawler dump trucks. The scientific novelty of the research results is to determine the dependence of the route length and the duration of the dump truck trip during deepening of the mining operations.
