Rock Blasting A Practical Treatise on the Means Employed in Blasting Rocks for Industrial Purposes

This practical guide walks listeners through the evolving world of industrial rock blasting in the late‑19th century, when steam‑driven drills and new explosives reshaped the trade. It explains how the shift from hand‑driven tools to machine boring demanded stronger charges such as nitro‑cellulose and nitroglycerine, and why electricity soon became the preferred method of ignition. The author balances technical detail with clear explanations, making the chemistry of modern explosives and the mechanics of early drilling equipment accessible to anyone curious about mining history.

The opening chapter focuses on the tools themselves, describing the simple yet robust steel “jumper” borer and the importance of a sharp, replaceable chisel edge. Readers learn why hardness and toughness are essential for cutting through unforgiving stone, and how designers accounted for rapid wear by shaping the drill for easy maintenance. By the end of this segment, listeners will have a solid grasp of the fundamentals that underpinned safer, more efficient blasting operations of the era.
