Due to the introduction of shock tube and electrical timing systems, development tunneling is for the first time feasible with possible using non-detonating cartridges.
In development blasting with Royex propellant cartridges no noxious gasses are present and as the whole system is 1.4S classified continuous mining operations are possible. No vibration is created so as in Slyping reduced safety distances for people, machinery and services are possible.
The absence of back-break means that hanging wall control is assured and there is much less need for costly and time consuming roof support and 'shotcreting'. Similarly in the absence of blasting damage permanent ventilation, water and services can be located far closer to the working face. The timing and versatility of the unique Royex and Maxfire System is perfectly matched to achieve multiple blasting patterns, firing sequences and loading options.
