Abstract

Abstract

Small-scale chemical explosion simulation experiments were carried out to investigate the leakage time and percentage of CO gas from different-scale chemical explosions in rock.The different-scale chemical explosions meted a scaling relation.The researched results show as follows: (1) the beginning time and stopping time of gas leakage are approximately proportional to the two-third power of the explosive quantities in scaled explosion experiments in similar media; (2) some materials in a sealed blast chamber can decompose into non-condensable gas under high temperature caused by explosion; (3) the percentages of the leaked CO in smaller charge scale experiments are not less than those in the larger charge scale experiments.According to the researched results, one can estimate the gas leakage in larger charge scale underground explosion by the metrical results in smaller charge explosion.
