Abstract.

Key trends of development of diamond mining industry in Republic of Angola are presented. Geological conditions of the Catoca quarry development were analyzed. As a result of the analysis, traffic routs were determined for the weight flows when cyclic-flow technology and steeply inclined conveyors are used. Types of transfer points inside the quarry and on its surface were substantiated. A primary crusher is assumed to be the best for mechanical crushing of the rock mass. A type of conveyor was chosen, and lumpiness of rock mass fed to such conveyor was substantiated. Location of transfer point inside the quarry is determined. Basing on the findings, a scheme for opening deep horizons in the Catoca quarry is proposed which assumes usage of cyclic-flow technology and steeply inclined conveyor. The scheme can increase output of this quarry.

Keywords:

cyclic-flow technology, steeply inclined conveyor, deep horizons of quarry.
