Abstract

"The aim of this thesis is an attempt to determine the relative efficiency, of four standard types of rock drills, as to air consumption. The air consumption was based upon the cubic inch of rock drilled by each machine. The orifice method of measurement being utilized, in connection with the exhaust to determine the desired consumption" – p. 1.
