Annotation:
The technological scheme of horizontal ore seams reprocessing by means of division on two blocks of open-cast field remaining to the moment of transferring into this technology is proposed. The order of roof and mining works progression by successive stages of reprocessing of blocks and filling of residual mined-out space is presented. The technological flowchart of the open-cast field separation on two blocks for reduction of worked out areas at Aleksandrovsky pit of Ordzhonikidze Mining and Concentrating Plant was investigated.
