Abstract. The objective of this work is to establish parameter conformity for the mine transport system, which includes excavator-automobile complexes, in order to create a mathematical model of optimal parameter calculation for mining works and their further use in models of design work. A mathematical model is developed, which initially analyzes rock geometry within the boundaries of the quarry fields, and then transforms the obtained results into the design and schedule of mining operations. It is proposed to optimize location of the highwall in the "Vostochnyy" quarry of the Ekibastuz coalfield by applying the excavator-automobile complexes in technology of surface mining operations. The objective is realized through sequential determination of design parameters for mining and opening-up areas by the following stages of the filed development: work of mining complex by continuous technology; work of overburden complex by cyclic-flow technology with using of the excavator-automobile complexes in the working area; and by cyclic technologies with usage of excavating and railway systems. In the work, the project time schedules of mining operations are compared for the whole period of the transport system reconstruction by existing and the proposed technologies, and as a result, an expert assessment is made concerning any needed changes in the design scheme of mining operations.

Keywords: quarry, coal, prolongated field, mine transport system, modeling, excavatorautomobile complexes.
