摘要
18 ABSTRACT The present invention relates to a mining method including the step of forming one or more sets of gate roads. Each set of gate roads includes at least two headings typically for providing and retuning ventilation. Dead end plunge cuts extend from the sets of gate roads. Each plunge cut is formed with a continuous miner coupled to a flexible conveyor system. Each plunge cut is greater than 30 metres in length. 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.
