Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The general methodology and technique for diagnosing indicators complexity of the structure of operating blocks in the open mining of ore deposits Y.P. GALCHENKO S.K. RUBTSOV The rapid increase of under development complex structure of deposits makes it very new urgency create common approaches and specific methods of diagnosing indicators complexity of the operational the structure of each block as a system consisting of an indeterminate number of ore and barren areas, the location and dimensions of which are set only on geological sections. Depending on the actual shape and overall length of contact between the ore and rock complexity of the structure the coefficient of each block is determined as the ratio of the total area of all the contact layers geological transects to their total area. The magnitude of this coefficient empirically allocated the grade 4 the structure complexity of operating blocks the expected value for different ore dilution obtained in step cleaning recess. It is experimentally proved that the difference between the expected and the actual diluting materials of ore with sufficient reliability characterizes the correct choice of breaking parameters and the possibility and feasibility of selective excavation of ore repulsed. Key words: open pit, complex structure deposits, diluting materials, breaking parameters, selective excavation. Contacts: E-mail: schtrek3@yandex.ru Pp. 52-55.
