APPLICATION OF CONTROLLED BLASTING TECHNIQUE IN IMPROVING SLOPE STABILITY IN THE OPEN-PIT MINE

For avoiding over-blasting to the slope and reducing blasting vibration to its damage in the open-pit mine,factors such as unit consumption of explosives,initiation mode and delay time etc were analyzed by combined with blasting feedback data,and suggestions which can be worked were provided about parameters of production blasting,buffer blasting and presplit blasting.
