Experimental Method Study on Emulsion Explosives under Hydrostatic Pressure in Models Blasting

Abstract:

Study on compression resistance of emulsion explosives can provide a theoretical basis for underwater blasting and deep-hole basting and development of emulsion explosives. Environment of deep water charge is simulated by a change of pressure of the micro-explosive device .The micro-explosive device was put in the reserved drill hole of mortar test block and applied rating pressure to explode, through fractal theory G-G-S lumpiness distribution function, which was used to date processing to study the fallen extent of explosion capability of emulsion explosives under hydrostatic pressure. The practice has shown that this is an effective new experimental method to study the fallen extent of explosion capability of emulsion explosives under hydrostatic through blasting effects.
