Overburden stripping and transport machinery at Zashulan coal mine

The article addresses challenges of open-pit mining in the Zashulan coal field, one of the most promising deposits of high-quality energy resources and raw materials with export potential. The field is located in the southwest of the Transbaikal territory and is operated under coal production license by Razrez Ugol, a joint venture established by Russia and China. The general information on the location, coal reserves, as well as geological and geotechnical conditions of mining in the coal field is provided. The main process solutions on drilling-andblasting, stripping and coal extraction are presented. The rational configuration of mining and transportation equipment is justified with a view to enhancing efficiency of stripping. All decisions are made subject to project capacity of the coal mine, structural complexity of coal seams and available operational and maintenance infrastructure in the region. The results of the analysis of the truck-and-shovel system efficiency in stripping are presented. The technical and economic assessment of stripping machinery options is given. The prospects of Zashulan coal mine operation and contribution to the infrastructure development and economic growth in the region are shown.
