Abstract: The methods of effective mining of coal deposits in an open manner are proposed, including increasing the operational productivity of dump trucks or reducing the duration of their movement in the cargo direction from the lower horizons to the upper ones. With the block order of mining of the quarry field, the options for driving off the side to create transport berms on ledges are considered in order to identify the most effective geometry of the working area satisfying the condition of minimal movement of dump trucks in the loaded direction up the side or completely excluding such movement, taking into account the dynamics of changes in the values of the decrease in the operational productivity of dump trucks and their dependence on the depth of the quarry field. For the most common dump trucks used in the transportation of overburden, the values of the effective depth of their use have been established with a link in load capacity. The variants of the board acceleration with an assessment of the economic efficiency of the movement of dump trucks from the places of loading in the face to unloading on the dump are determined. The relationship between the change in the cost and the efficiency of the acceleration of the board, taking into account payments for environmental payments for the placement of rocks in external dumps and the purchase of additional units of dump trucks, has been established.
