Wirtgen surface Mining in Russia: Selective limestone mining without drilling or blasting. A member of the Eurocement Group, the mine ZAO Kavkazcement is located near the Black Sea in Russia and is one of the largest cement producers in the Northern Caucasus.
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)
