Quick Summary

A stoper drill, also known as a stoper, is a type of hammer drill used in mining. It is mounted on a pneumatic feed cylinder and is specifically designed for drilling vertical and inclined holes within stopes. A stope is an area in a mine where ore is extracted.1

The stoper drill is a specialized piece of drilling machinery that evolved from earlier rock drills. Innovations like the hammering action and air-leg feed, which helps hold the machine in place and advance the drill steel into the rock, became important features in modern stopers. These drills are crucial for operations in mining and certain tunneling activities.2
