Millisecond shooting at Sydney Mines and Glace Bay, Nova Scotia resulted in elimination of misfires due to air concussion or water hammer, better fragmentation of rock, improved placing or spreading of debris, improved squaring of roof and sides, less tendency to cause overbreak, improvement in tunneling advance, elimination of cutoff holes, and reduction in explosives per cu yd of excavation.
