The influence of the mining depth and the pit productivity on the effectiveness of the technological scheme application for the development of construction material deposits when using a mobile crushing and sorting complex (MCSC) at mining faces in the pits was determined. Analytical, statistical, graphical, analytical, and techno-economic analyses...
Providing the national and world economy with mineral raw materials is an integral part of development and scientific and technological progress. The modern world is moving to new forms of interaction, concentrating its trends on digitalization, computerization and automation of all processes of human life. However, these trends require the use of...
Purpose. To establish the influence of the quarry depth at the construction materials deposit mining on the payback period of investments when using the haulage mining system (HMS), cyclic flow technology (CFT), and mobile crushing and sorting plant (MCSP) with a comparison of its efficiency. Methods. The research used discounted value of cash flow...
The paper examines the technological scheme for granite mining with the use of rock chutes in the conditions of the Rybalsky Quarry. The research purpose is to substantiate effective technological schemes for mining the upper granite quarry horizons to reduce mining costs and improve the final product quality. Research is conducted using: the metho...
The paper examines a complicated non-transport system for mining a gently sloping fireclay deposit using ESH-10/70 dragline excavators. The research purpose is to substantiate the technological scheme of stripping operations and determine their parameters to reduce the strip-mining costs. Theoretical research is performed using the following method...
Artykuł poświęcony jest zagadnieniu efektywnego wykorzystania minerałów towarzyszących przy zagospodarowaniu złóż rud tytanowo-cyrkonowych. Ponieważ złoża osadowych rud tytanowo-cyrkonowych mają duże powierzchnie, setki milionów ton masy wydobywczej podczas ich eksploatacji przekształcane są w formacje antropogeniczne. Z całej masy wydobywczej zale...
Purpose. Establish an effective direction of the mining front direction in the beams locations at the development of a placer mineral deposit. Research methodology. The analytical method of research was used at the development of a method for determining the time of mining a pit section with a crossed beam surface when applying schemes with longitu...
The porpoise of the research is to develop technological schemes of overburden rocks extraction on the outstripping overburden bench with a further rational scheme choice in the curvilinear quarry contour conditions. Research methods – theoretical and experimental; graphic-analytical method; method of statistical and system analysis; method of tech...
Purpose. Develop method for predicting the displacement of ore contours in the shotpile after the explosion to planning the ore raw materials selective mining at the development of iron ore quarries. Research methodology. Actual surface measurements were used to determine the loosening coefficient for individual sections of rock mass collapse. The...
The research aim is establishment of effective parameters for mining of flooded bench by a hydro-mechanized complex with dumping of enclosing rocks in a sludge pond of pit residual space. The established research results make it possible to choose the effective width of the dredger mining cut at the hydromechanical method, taking into account the v...
The research aims to increase the performance efficiency of hydromechanization equipment under the conditions of pit operation of the Motronivskyi Mining and Concentrating Plant by determining the dynamics of change in the water level in the mine workings when developing the overburden rocks and mineral. It has been generalized the world experience...
This article is devoted to the conceptual development of the transition from drill and blast excavation to a non-blasting method for the preparation of hard rock before excavation at construction material deposits. The scientific and technical literature on the problems in the blasting of hard rock in preparation for excavation is analysed. A classi...
Purpose. Development of the process scheme of mining-hauling operations at the mining flooded deposits. Methodology. The choice of rational haulage equipment according to the conditions of mining flooded Motronivskyi placer deposit is performed by using the analytical method of research. The graphic-analytical method of research was used in develop...
Purpose. The economic efficiency definition of cut-off walls in rocks at the flooded Motronivskyi mining site of Malyshevskyi deposit taking into account the environmental aspects of the problem. Methodology. For determination of possible technological solutions to reduce the inflow of groundwater into the pit used, methods of analysis and systemat...
Purpose. Substantiation of effective ways of mining titanium-zirconium ores deposits with high levels of flooding at the exploration Motronivskyi site of Malyshevskyi Deposit. methodology. The correct definition of hydrogeological parameters on Motronivskyi site by constructing wells in the relief depressions for the establishment of an average fil...
Purpose. To determine factors influencing the development process of a mining and metallurgical enterprise and trends of the market environment and to substantiate different development strategies for mining companies. Methodology. The basic procedure for the analysis of changes in the market environment is estimation of the complex indicator of th...
