抄録

In order to investigate the mechanism of the rock blasting, it is considered to be very important to know the amount of pressure produced on the inner surface of the charge hole by the.detonation of an explosive. Therefore, by means of observing the stress wave produced within a steel rod by the detonation of an explosive which was placed in contact with this rod in a charge hole, the amount of the peak pressure acted on the inner surface of the charge hole was estimated and the state of rise and fall of the pressure with time was measured.<BR>As the principal results of the present experiments, it was found that the detonation pressure was mostly influenced by the variation of the detonation velocity which was controlled by the effect of confinement and the detonation pressure of the confined 45 grams of No.3 Take Dynamite attained 1.5 times as large as that of the same explosive fire' freely in air and also that the duration time of such detonation pressure in a charge hole ranged from about half a millisecond up to several milliseconds.
