PARAMETERS OF DRILLING-AND-BLASTING OPERATIONS FOR THE USE EMULSION EXPLOSIVES

The analysis of experience of emulsion explosives application for the last 10
years has allowed to establish a tendency for increasing in their usage on
underground mining operations. Safety of operations conducting, smaller volumes
of products of explosion and high power rates of emulsion explosives lead to
decrease in influence on a condition of miner and atmospheric air. However, lack of
the approved and widely applied method of calculation of drilling-and-blasting
operations parameters which consider power characteristics of emulsion explosives
constrain their implementation.
