164 REPORT OF THE BUREAU OF MINES. Off. Doc.
report was completed.
At Beaver Meadow the new breaker mentioned in last year's
The drainage tunnel continued and air compressor,
with two air motors, installed at Slope No. 2. Contracts
were let to Cuyle Brothers to extend No. 8 stripping westward and
start the stripping of the Greenfield basin in extension of the old
east spoon end strippings.
Tomhicken was continued on the same principles as it was worked
during 1899, viz: hauling the coal in mine cars or flat cars to Deringer
for preparation.
At Derringer and Gowen, the rock plane mentioned in last year's
report, developing and draining overlying veins west of Gowen
colliery, has been completed. An air compressor has been installed
at Derringer to furnish motive power for hoisting engine and pump
underground. The air will be furnished at 90 pounds pressure. Another
air compressor will be installed to furnish air for haulage
on the same basis as the Beaver Meadow and Oneida plant. A
hoisting engine and pump are to be used on a new slope to open
lower levels in the northern basin of Gowen, Slope No. 4, which
is the extension of the Derringer deep basin westward, as two proving
slopes had been sunk, which developed a large area. Mechanical
contrivances were necessary to develop this territory; hence, the
installation of compressed air plant.
