Abstract

"Numerous methods of stoping have been used in the mines of the Butte District, Butte, Montana, depending on the shape of the ore bodies, conditions of the walls and presence of fault zones or heavy ground. One of the methods tried out successfully in the past few years is that of using rill stopes, both open and timbered. The ideal conditions for adopting this method of mining require veins with nearly vertical dip so that the ore will slide into the chute. The author attempts to describe the various steps including how the development is done, how the stopes are started and carried to the level above"--Introduction, page 1.
