Abstract
[ ABSTRACT] As an important parameter to determine the reasonable charge diameter and avoid misfire and incomplete detonation, the critical diameter of explosive has a vital signification on performance improvement and utilization efficiency. In this paper, a continuous pressure-conduct probe and wedge charge device was designed to measure the detonation veloci-ty of the explosive and its critical diameter was determined using the incomplete detonation characteristics and locating the detonation inflection point. The experimental results on the ANFO having a charge density of 0. 9 g/cm3 show a detonation velocity of 3 261 m/s and a critical diameter of 12. 5 mm. It provides a simple and low cost method for testing detonation velocity and critical diameter of explosives at one time, which can be taken as a guideline for the determination of explosive parameters.关键词
