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
