Excerpt from New Methods of Testing Explosives

Until about fifteen years ago black' powder and dynamite were almost the only explosives used in practical mining. The danger entailed by their use in workings where gas was met with, had, however, been generally recognised, and the admitted expediency of abolishing their employment in fiery mines or seams presently brought about a material change of affairs.

Today, the use Of gunpowder has almost entirely ceased in collieries troubled with gas, and even in quarries it has been largely abandoned. Dynamite has perhaps stood its ground rather better, but this material, too, has had to yield wherever pit-gas or dangerous quantities Of coal-dust abounded, both in fact being almost universally superseded nowadays by so-called safety explosives.
