An Underground Mining System for reduced costs, improved efficiencies, higher productivity and a safer working environment through Penetrated Block Extraction

摘要

The present invention relates to a mine including one or more sets of gate roads. Each set of gate roads includes at least two headings. Dead end plunge cuts extend from the sets of gate roads. Advantageously, narrow elongate pillars may be left between adjacent plunge cuts, thereby resulting in greater material removal per volume and improved operating costs when compared with bord and pillar mining.
