Quarry Operations tpubH BLASTING IN SURFACE EXCAVATION Mining and Blasting

QUARRY OPERATIONS Quarrying involves not only extraction of material rock but also crushing and screening that makes the rock suitable for use as construction material Quarry Terminology Figure 5 10 shows the names of various quarry featurBlast Design The best use of explosives is made when a blast produces a clean break giving good fragmentation while avoiding excessive fly rock The success of achieving these goals depends significantly on good blast design If the blastholes are drilled as a staggered pattern on an equilateral triangular grid the optimum distribution of the
