Abstract

Applying a solitary explosion in rock environment will make the contiguous zone destructive. This report shows the determination of destructive radius when applying a solitary explosion in underground construction. The calculation is established based on the determination of the stress field caused by explosion wave in the environment. The math test is determined by solving the equation of stress wave distribution in rock environment knowing the tensile strength limit. The result of the research could be used to indicate the distance between two explosives when using explosives to break the block stone.
