【Abstract】 This paper discussed the basic characteristic of deep air-decked charge and selection of different position for air-decked and the results of blasting experiment of different position for air-decked charge and application effect in the mines,which shows that the existence of the air-decked charge at hole’s bottom position can regulate the blasting air effect,growing reaction time,improving rock blasting quality,decreasing blasting seismic and consumption of explosives,and also have the advantages of operational safety and simply.更多还原
