Richard
Brown, GMA engineer in 1826, tells of crude methods used in
a Sydney main, first opened in 1785. As workings advanced
from the shore in a westerly direction, new shafts were sunk
at intervals of about 200 yards so that the length of haulage
from the faces of the bords to the bottom of the shaft never
exceeded that distance.
Brown
also said that coal was hauled in two-bushel tubs on small
iron-shod sledges, over a roadway formed of round poles, two
to three inches in diameter, laid transversely. After 1827,
steam-hoisting engines were installed and used in the movement
of coal in the mines, according to author, C. Gerow.
To
move materials into the mine and to remove coal, rails were
laid from the slope shaft bottom to the working areas of the
mine. Horses or "pit ponies" were first used for
this haulage. During and following the First World War, underground
mechanical haulage began to replace the horses and gravity
balance systems in the mines of Pictou County. It was also
in that area, sometime around 1890-1900, that air-driven machines
were installed.
In
some of the working areas of the old mines, a system of overhead
pulleys and cables pulled materials in coal boxes along the
rails to workplaces where horses or "balance systems"
took over.
In
the early 1920s, small air or electric hoisting engines began
to replace horses in the balances and sinkings, and in due
course gradually took over from "horse draft."In
a report dated June 1925, author J.R. Dinn talked of underground
haulage in Cape Breton mines. He noted four distinct operations
in the movement of coal from the faces to the pit bottom:
horse, single-rope, main and tail rope and endless rope.
"It was necessary to haul coal either by horses or by
pushing it to the headway which was driven to the dip and
rise. The cars were gathered by an electric or air hoist and
lowered on a headway (a passage connecting other passages),
to a level road, from which point they are hauled by main
and tail, or by single-rope engines to the landing at the
main deep. From this point, they were transferred to an endless
system which delivered coal to the shaft or bottom or tipple."
In 1948, mine cars were hauled at up to 8 miles per hour by
electric and diesel locomotives.
