Abstract: The coal-bearing zone on open pit mines is in most cases a rock-and-coal massif including strata of simple and complex coal seams with varying an-gles of incidence, thickness, and coal quality. The specific weight of this zone in the total volume of the minerals and rocks in the quarry field reaches 80% and more. A feature of mining of coal-bearing zones of quarry fields is the presence of complex rock-and-coal slopes, including coal layers of simple and complex structure, different conditions of occurrence. The processing of these slopes (panels) requires the use of several excavating and loading machines and auxiliary equip-ment. In the coal-bearing zone of the quarry, it is practically impossible to distin-guish independent rock or coal slope. Within the excavation slope, low-strength strata are encountered, not only with different angles of incidence, but also with different angles of their crossing to the face. The classification of excavator faces’ technological schemes suggested in the article allows to solve operational problems to ensure the reduction of current costs for overburden and coal losses.
