Abstract

Gas in exploded boreholes experiences very high temperature and pressure which prohibit the use of the ideal gas law, PV = nRT. However, non-ideal gaseous mixtures can be described by the compressibility factor, Z, which measures the deviation of a real gas from ideal gas behavior. The Z-factors for real gases are nearly equal when the gases have the same reduced temperature and pressure. Application of Kay's Law permits direct calculation of the explosion state parameters. The detonation state conditions, used in earlier efforts to describe non-ideal explosive gas behavior, may be neglected. © 1984.
