(Above)  Mine equipment is rubber-tired.  MHAers enjoy the ride in a pick-up/tractor-like rig that easily handles the 12% grades in the mine’s ramp system.

 

(Right) A mobile bolting machine installs split-set roof bolts and wire mesh to secure the back (roof) and ribs (sides) before the next cut can be made at the rock face.  The operator in a protective cab is able to stay under the supported roof as he drills holes and installs the bolts and mesh.

(Left) A rubber-tired drilling jumbo drills holes in the ore for explosives.  The operator controls the drills from the cab following the pattern marked in blue paint on the face by the mine engineers. Each boom of the jumbo operates independently.  Note the roof bolts and wire mesh on the back.

An even closer view shows the white quartz vein crossing the face from the upper left to the lower right.  When the ore has been blasted, loaded, and hauled away, the stope is backfilled with cemented mill tailings.  These become the floor for the stope above as mining the vein continues.

A mine haul truck transports the ore from a stope to an ore pass through which it drops to a lower level.  From there, the ore is conveyed out of the mine and to the mill.
