Excerpt from The Effect of Stemming on the Efficiency of Explosives
The preliminary experiments having shown a remarkable gain in effect by the use of stemming, several similar experiments were per formed to make sure that the gain was not the outcome of chance or accident, but was really due to the use of stemming. In all these experiments, however, it was found that when stemming was used the enlargement of the bore hole was increased about 88 per cent. Thus the experiments showed conclusively that a given quantity of 40 per cent strength ammonia dynamite, with stemming, will do the same amount of work as a much larger quantity of the same explosive without stemming.
