Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in drilling contractors rocks to generate more gas pressure and a greater heaving effect. The standard method for blasting rocks was to drill a hole to a considerable depth and deposit a charge of gunpowder at the further end of the hole and then fill the remainder of the hole with clay or some other soft mineral substance, well rammed, to make it as tight as possible. A wire laid in the hole during this process was then removed and replaced with a train of gunpowder. The uncertainty of this method led to many accidents and various measures were introduced to improve safety for those involved.

One was replacing the iron wire, by which the passage for the gunpowder is formed, with one of copper. Another was the use of a safety fuse.
