“…Much attention is given to research of the mining equipment structural characteristics influence on the effectiveness of the quality management of non-metallic building materials; thus, the paper (Nenashev, A.S., Fedotenko, V.S., 2011) investigates the influence of bucket capacity and a technological scheme on the performance of excavation of a rock mass; but a mathematical model of the rock mass excavation process of a backhoe type excavator to estimate a layer, which is separated by scooping, and the filling ratio of the bucket at different points of the excavator slaughter is developed in the paper (Strelnikov, A.V., Tioulenev, M.A., 2011); while the optimal geometric dimensions of the bucket are proven and the efficiency of a backhoe type excavator when using buckets of various sizes is investigated in the research (Komissarov, A.P., et al, 2006;Pobegailo P.А., 2014). Intensification of technological processes in drilling and blasting operations during open-cut mining and organization of dumping stations with combined transport types are investigated in the publication (Zairov, Sh., et al, 2018;Abdellah, W.R., et al, 2018;Sobko, B., et al, 2017;Shustov, О., Dryzhenko, А., 2016).…”

The influence of primary kaolin moisture on the duration of bucket unloading is proven, and the analytical dependence for the estimation of this ratio in the form of a second-degree polynomial is obtained. Three main technological schemes for different technological conditions substantiate the procedure for evaluating the productivity of the primary kaolin excavation for cases of selective development of curvilinear sections on the basis of the first proposed technological coefficient of the contact form, which takes into account the fractal nature of the section's shape, are suggested in the article. It is first proposed to include the specific time of shifting in the working cycle of backhoe type excavators. The mathematical models of the primary kaolin excavation process on the curved face of the conditioned area with a backhoe type excavator for different varieties of the mutual arrangement of the hydraulic excavator and the hauler are developed.

“…Витрати на транспортування гірничої маси автосамоскидами більші, ніж конвеєрним підйомником [3]. Тому для ефективного використання комбінованого авто-мобільно-конвеєрного транспорту горизонт встановлення перевантажувального пункту необхідно з часом переносити вглиб через кожні 90-105 м [4].…”

Purpose. Substantiation of efficiency of the combined in-pit automobile-conveyor transport scheme with through passage of dump trucks at their unloading from the point of view of economic, technological and ecological conditions of transition to the new scheme of transport. Methodology. To substantiate the effectiveness of the proposed scheme with through-dump trucks during their unloading, a systematic approach was used, which takes into account the economic, technological and ecological conditions of the transition to the new transport scheme and formulated on their basis provisions for the introduction of new combined mining transport. Findings Four schemes of combined automobile-conveyor transport were compared: with a dead-end front and a dead-end unloading, with a through front and a dead-end unloading, with a dead-end front and a through passage with a through front and a through passage of dump trucks. The most effective under the three conditions of transition to the new transport scheme are schemes with through passage of dump trucks at their unloading. Originality. In addition to the known four types of reloading devices with throughpassage of dump trucks: with a drawbridge, with a transverse drawbridge, with drive beams and a swivel platform, the fifth type of reloading devices was first identifiedwith swivel bridges, swivel axles to support beams (transport tracks) with the possibility of rotation in the vertical plane. This design allows you to abandon the drive, and the rotation of the unloading bridges to conduct due to the force of gravity of the rock mass.Физико-технические проблемы горного производства 2021, вып. 23 201 Practical implications. It is established that the introduction of schemes with through passage of dump trucks allows to reduce the volume of mining and capital works by 2.7-7.5 million m 3 , fuel consumption by 150 thousand liters (2 liters for each transport cycle of dump trucks), to save land. from violation by open mining operations of 5-13 hectares, depending on the model of dump trucks used for transportation of rock mass and the depth of construction of the transshipment point.

Purpose. To determine rational technological scheme of extracting mineral resources in the steep excavation layer in non-metallic hard minerals quarries while delivering rock mass from the quarry to the surface processing complex by mobile conveyors' system with crushing complex. Methods. For scientific, theoretical and practical studies we used analytical, graphical and statistical research methods. Findings.Based on previous studies of non-metallic deposits systematization, we worked out a rational technological scheme for extracting mineral resources in the steep excavation layer in non-metallic quarries while delivering rock mass from the quarry to the surface processing complex by mobile conveyor's system with crushing complex. The results of these studies are reflected in identified dependences between parameters of the development system which allowed to determine the efficiency of utilizing the selected technological scheme of extracting mineral resources in the steep excavation layer.Originality. New dependences between parameters of the development system in basic non-metallic quarries have been determined, such as: changes in the general mileage of a front loader related to productivity of quarries and the average distance transportation of minerals related to productivity of quarries.Practical implications. The results of this research will be used for practical applications in the design of mining companies extracting raw materials for production of crushed stone.
