A new Hue of colamn pipe 1,730 feet in lengtli has been placed in this
slope, and a 14-inch plunder pump formerly used at the upper lift has
been placed at the lower lift.
No. ^ Slojx.—This new slope, which is located at the eastern end of
the property, has been opened to the basin in tlie Buck mountain vein,
and g-angways driven 800 feet east and 530 feet west during the year
past. A pair of double hoisting engines with friction drum have been
set up here, and four cylinder boilers 36 inches in diameter and 36 feet
long have been placed in ])osition and connected with a 50-foot iron
smoke stack. An exhaust fan has been erected and all the machinery
is substantially housed. A duplex pump has been put at the foot of
slope, having steam cylinders 26 by 48 inches with 12 by 48 inch
plungers and provided with suitable steam and column pipe.
This company during the past year has spent considerable money in
digging ditches and channels to conduct surface water so as to prevent
its going down the cave holes on the outcrop and having to be pumped
out of the mine at one slope, Avith the result of, perhaps, the larger part
it returning to the sump of the next slope, and their Avork covers more
than two milesof such channels and ditches and represents money saved
to the company.
CM. Dodson d: Co., Beaver Brook colliery.—This company has added
two forty horse power, Dimmick ct Smith boilers to its steam plant,
besides lengthening out another set of boilers from 36 to 42 feet and adding
" mud dams."
No. 11 slope has been opened up about 300 feet on the north pitch of
the north basin, but has not yet reached the basin. The total depth
from the top of slope is 378 feet, Avith an average pitch of 60°. To
avoid all danger from Avater in the overflowing Wharton vein workings,
the company has Avisely decided to pump the Avater out before sinking
this Buck mountain slope any farther.
George H. Myers d' Co., Yorktoion.—M the No. 1 slope of this colliery
a shaft has been sunk inside from the Mammoth vein to the Buck
mountain vein, a depth of 278 feet 7 inches. It cuts the Wharton vein
at a distance of 116 feet from the bottom of Mammoth vein to bottom of
Wharton vein. The Wharton vein is iound 9 feet thick and the Buck
mountain vein 10 feet thick. The shaft is provided with safety gates
at the Mammoth and Wharton veins Avhich are well arranged. The
hosting engines are placed on the surface and the rope passes doAvn
through a six-inch bore-hole drilled for the purpose.
M. S. Kemmerer d'. Co., Sandy Bun.—At this colliery a tunnel 120 feet
long Avas driven through the rock to the Avorkings of No. 1 slope, to
drain a portion of those Avorkings, and to cut off 90 feet of the lift of the
pumps in the slope.
No. 11 slope has been opened from the first lift to the basin, a depth
of 450 feet from the surface, to get back of the scpieeze in old No. 4
Avorkings.
