Abstract: Specific weight of expenses for transportation of rock mass in the cost of coal mining on Arshanovsky open pit is 55%. The development of coal reserves is carried out in the northeastern part of the license area. The existing quarry excavation consists of two longitudinal mine workings carried out along the most powerful coal seams 15 and 19. The quarry is opened by trenching. Transportation of rock mass is carried out through flanks along the ends of the quarry. The use of the opening-up scheme with the transport bridges will reduce the transportation distance of the rock mass, and, as a result, significantly reduce costs. This article deals with the option of forming a transport bridge along the bottom of seam 15 to connect the working horizons of seams 19, 19a and 19b to the external dump and the coal transfer point. This will make it possible to reorient the freight traffic from the ends to the central part of the quarry, and to reduce the average weighted distance of transportation of the overburden and coal by 0.2 and 0.3 km, respectively.
