in Nevada, blasting in a drift caused a roof fall in another drift situated about 25 ft below the blasted drift. When the blast occurred in the upper drift, about 40 to 50 tons of material above the anchorage zone, supported by 6-ft roof bolts, fell as a result of the blast. Blasting often causes redistribution of stress in pillars and roof area.
