Interrelations between technological processes of open-pit mining

Introduction. High productivity in mining processes is possible only with sufficient consistency between processes: drilling – blasting excavation transportation. The relationships and are most well studied, although there also a number of issues related to the interpretation data choice efficiency criteria. further link by transportation incomplete, therefore, no clear direction systematic coordinated cost optimization processes. Getting one process can lead inefficiency adjacent Therefore, it desirable that criteria for work were universal and, at same time, could reflect individual specifics process. purpose research. research was establish links taking into account their energy characteristics. Research methodology. In course research, modeling wells, explosive destruction, widely used. Methods mathematical statistics, system analysis, synthesis, field experiments used identify relationships. Model representations compared practical boundary conditions specified. results. As result characteristic has been established, which consumption per 1 cubic meter (J/m3 ). case geometrically, these costs spent on destroying volume rock beaten off well. For excavation, this loading mass, properties dependent destruction quality explosion, characterized geometric parameters collapse intensity work. Conclusion. It revealed establishment extraction allows not evaluate efficiency, but opens up possibility regulate specified calculating cycles required face timely delivery appropriate vehicles, be basis more accurate statements problems, including anisotropy mountain range variety influencing organizational technological factors operations. advisable develop processing, as suggested I. A. Tangaev. To crushing crushing. Considering modern systems dispatching monitoring machines allow collecting real-time information from sensors main nodes working equipment, network technologies tracking real then matching processes, or changing balance, you quickly This significantly affect practice making managerial decisions.
