An innovative scaled model to simulate the perimeter hole blasting in tunnel, in Proceedings of the 19th International Symposium on Mine planning and equipment selection (MPES) conference, Dec 1-3 2010, Fremantle, WA, Australia: Carlton South, Vic.: AusIMM.

The success of smooth blasting essentially depends on geological condition of rock. Also, in the perimeter hole, borehole pressures with light, well-distributed explosive loads are important to minimise overbreak. In order to simulate perimeter holes with scaled model test, the borehole pressure was considered as a factor of scale. Hydraulic oil pressure is applied as borehole pressure instead of using explosives and detonators in order to remove the undesirable effects of detonators in an experimental set-up of just two perimeter holes in a tunnel blast. The borehole pressure on a perimeter hole is nearly reproduced with hydraulic pressure which is generated by non-electric detonators in the hermetical cylinder.
