Abstract
A large scale blasting is necessary for the construction or road, harbor or ground foundation of building and it is common that the blasting work is performed by a specialist subcontracted from the construction company who is originally responsible for the project. Sometimes the latter do not agree with the former in total amount of blasted rock. They try to find out real work amount as precisely as possible. The estimation is sometimes carried out by an entrusted person when it is impossible to come to an agreement with each other. There are several methods in estimating the blasted rock volume; a calculation by prescribed equivalents of explosive before construction, a calculation by specific charge per unit volume of rock, and a calculation by rock volume per detonator. In this study, the last method is reviewed and recommended as most reliable one.
