Influence of Physical Sensitizing Agent on Compression Resistance of Deep Water of Emulsion Explosives

Abstract:

A study of emulsion explosive of deep-water pressure performance can provide theoretical basis for underwater blasting, deep hole blasting and the design of emulsion explosive. The sensitizer is the heavier components of emulsion explosive, using reusable experimental device to simulate the environment of deep water charge, perlite and glass microspheres in two kinds of commonly used physical sensitizing agent content on properties of emulsion explosives with deep water pressure effect. The experimental results show that : with the increasing of the content of physical sensitizing agent, emulsion explosive of deep-water pressure performance also gradually improve, when the pressure is larger, the effect is particularly pronounced; in a certain range, with the increase of the content of physical sensitizing agent, emulsified explosive performance also gradually improve, but reaches a certain value, the explosion properties but declined; in emulsion matrix under the same conditions, the perlite content of 5%, glass microspheres content is 2%, the emulsion explosive has good resistance to water pressure and explosion properties.
