摘要

If innovation is the key to survival, then it is vital to consider new approaches to oldchallenges. This paper presents three such innovative solutions and the reasoning behindthem. All are based on hydropower technology, that is, the use of high-pressure waterhydraulicsto power mining operations, to improve the working environment, and to saveenergy. The first solution harnesses the ability of water-powered, in-the-hole (ITH) hammersto drill long, straight holes accurately, to develop orepasses, to drill blasting 'slots' in massiveorebodies, and to drill long, large-diameter (105 to 350 mm) service holes. The secondsolution describes using a monorail-mounted drill rig to speedily develop wide, tee-shapedraises, thus opening up stope face length more profitably than conventional alternatives. Italso promises a safe new mechanized mining method for narrow, dipping, tabular orebodies.Lastly, developments in hand-held drilling systems are reported. These offer reductions inenergy and water usage, improvements in productivity and mining efficiencies, and can beretrofitted in existing conventional operations. Importantly, all three solutions requirerelatively little capital and have low all-in operating costs
