As a quarry blasting technique the Royex rock breaking system can be used both as a primary and secondary blast or rock breaking alternative. Since the system is very precise and causes minimal rock vibrations and fly rocks , drilling and blasting operations can be done simultaneously. This also means that efficient quarrying is possible close to other structures and in cities.
