Abstract
The authors have developed a procedure for selecting models and number of draglines for overburden removal in direct dumping within the hybrid opencast/underground mining in gently dipping coal seams. The potential opencast production capacity algorithm uses the data on the available workable reserves, life of assets, and geotechnical conditions of mining. The article presents a case study of the procedure in determination of working capacity and number of draglines so that to ensure project capacity of the direct dumping system in certain geotechnical conditions of surface mining in a suite of coal seams.
