With the introduction of the machine drill, several significant changes occurred in the process and the methods used for blasting rocks in industrial operations during the 19th century. These changes were introduced because the procedures carried on by hand proved inefficient and dangerous for the people performing them. This work presents a detailed and precise account of the modifications made in mining practices after new tools were introduced. The author describes the functions of several devices and explosives used for rock blasting in detail. Contents include: The Tools, Machines, and other Appliances used in Rock Blasting Explosive Agents used in Rock Blasting The Principles of Rock Blasting The Operations of Rock Blasting Subaqueous Blasting
