Optimization of mining schedule during safe development of working zones along steeply inclined open pit edges

摘要

An algorithm for optimizing the mining schedule has been developed using the example of the "Vostochnyi" coal mine of the Ekibastuz region to implement the technology of safe intensive development of working zones along the steep open pit edge. Optimization operations of the mining operations mode and the transformation of its results into a mining schedule are combined in one algorithm. It will allow technical service to adjust the approved project schedule of mining operations at the end of each calendar year, depending on the actual volumes of coal mining and overburden excavation with recalculation of the required stripping volumes. Thus, this method of rapid assessment of design solutions while combining optimization of the open pit-mining mode and the schedule of their production allows, with a change of demand on commercial products, to correct the required volumes of stripping operations, taking into account the production rhythm of overburden, mining and mining preparatory operations.
