ABSTRACT AUTOMATIC ROOF BOLTING DRILL RETENTION APPARATUS A drill steel support assembly for a mining roof bolting machine is presented. The assembly is utilized for retaining and guiding a drill steel on a roof bolt- ing machine during the collaring of the drill steel in the mine roof. Once collared, the drill steel is re- leased by the retaining assembly inasmuch as the latter is not necessary for support purposes after collaring has occurred. The release of the drill steel from the retaining assembly is accomplished when the vibrations from the drill steel are sufficient to open the support mechanism once the drill has been collared.
