This study evolves the theory and practice of completing equipment involved in the cyclical-and-continuous method (CCM) of mining with vehicle–conveyor–rail transport. Earlier R&D projects mostly deal with extended fields of open pit mines. This study focuses on rounded mine fields. One of the problems of CCM efficiency yet remains the project capacity of expensive lifting conveyors (which is reached not more than by 50–60% by now) and the reduction in cutback in open pit mines in order to accommodate facilities for rehandling of rocks from trucks to conveyor and from conveyor to rail transport. In this regard, the object of this study is maximum uniform loading of lifting conveyor by means of continuous rehandling of rocks from trucks to the conveyor and from the conveyor to rail transport on a regular basis, at the minimum dimensions of the rehandling and conveying–loading sites. The key methods are: novel designs of CCM equipment elements; theoretical development of CCM equipment through systematization of lifting–transport–rehandling facilities. Improved efficiency of CCM can be reached with: a through-unloading point meant to eliminate maneuvering of trucks and to ensure maximum continuous and uniform loading of the lifting conveyor; a high-angle tube-type conveyor for coarse rocks after minimized pre-crushing; a rehandling device for loading of rocks from the conveyor to dumpcars arranged on two horizons, at the reduction in the width of transport–rehandling sites by 1.3–1.5 times. For mining-and-transport systems, the transportation devices within CCM equipment are compared, the lifting transport within CCM equipment for steep slopes of deep open pits is systematized, and classifications are proposed for rehandling and unloading facilities with through passage for dump trucks.
