Introduction. Fly rock throw can be increased, either because rock removal by the previous explosion is in a too advanced stage, or because it is still insufficient; in the first case, burden is too small, in the second is too high and the ejection of stemming can take place, due to guneffect.
In normal blasting all holes do not blast at the same time. Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden (Be)
The many advantages of blast fishing are clearly shown, and no longer do we need to bother with pesky green ideas like coral aquaculture, sustainable fisheries, reef management. Diving tourism may be the only real industry negatively affected, but divers are an annoying lot for the most part.
