RBP File No. 4242-1276 ROGERS, BERESKIN & PARR CANADA Title: LOW LEVEL BLASTING COMPOSITION AND METHOD OF BLASTING SAME Inventor: David L. Coursen Rufus E. Flinchum ABSTRACT OF THE INVENTION A blasting agent is disclosed for use in a borehole having a pressure resistant closure. The blasting agent is used in combination with a primary initiating system comprised of a detonator and an initiator for the detonator. The blasting agent is preferably a semi-fluid explosive material having a pre-determined sensitivity. The sensitivity is related to the borehole diameter and the initiating system's strength, wherein the blasting agent upon initiation is transformed into explosive products by means of reaction front which consumes substantially all the blasting agent as the reaction front passes through the blasting agent. The reaction front has an average velocity of propagation of between 200 metres/second and 1,000 metres/second for at least 30 % of the total length of blasting agent located in the borehole. Another aspect of the invention is a method of blasting wherein the average velocity of propagation of the explosive front in the blasting agent is in a range of between 200 m/sec and 1,000 m/sec.
