CONTROLLED ROCK BLAST DESIGN ON THE HIGHWAY VRGORAC-PLOČE
During the last decade - effective blast monitoring tools, effective blast design tools, geophysical exploration of rock masses, rock mass mapping and modelling system and fragmentation measurement system - have been developed and can now be applied to the problem of both estimating and achieving more controlled fragmentation. In the practical blasting , pre-blast assessment of rock mass, choice of appropriate geometry and diameter of boreholes, explosive parameters and blasting control are the most important parameters that influence blasting results. In blasting there is always the question of how the blast has performed relative to the results required by the quarry, road building or mine operator. The assessment of blasting results generally considers such factors as: fragmentation and the percentage of oversize, muck pile profile back break and back throw, flyrock and vibration and vibration and airblast. Rock excavation by blasting for the highway is held in complex environment. Such conditions force restrictive criteria which protect environment from seismic influence and mechanical damage. Drilling and blasting plans on highways should be designed in the manner that professional personnel could carry out procedures in the safe manner.
