![]() The fragments adopt a ballistic trajectory.The pressure of these gases applied to the face of the fragments, produces forces that propel the fragments. ![]() ![]() ![]() Gas pressure is reduced via the cracks thus separating the rock fragments.This damage is the center of the cracks in the rock.This strain field, due to its impulsion aspect, creates a strain wave that is propagated in the rock and damages the rock.The gases are applied to the borehole which contains them and this creates a strain field in the rock.The charge explodes and is split up into high-pressure, high-temperature zones.The effects of an explosion (blast) are as follows: Here is an interesting bit of deep technology from the article. Software for Mining and Mines Safety System:Īn article on the new software and on the associated technologies of blasting and fragmentation is to be found at this link, a paper from the September 2008 issue of International Mining. List of Technical Papers / Presentations.
