Method Of Procedure.
. When all preliminary preparations
had been completed actual pumping
, and bailing was started on March Is
The system followed, briefly outlined
ed in the pump compartment and bail
ing was continuously carried on In the
other two compartments until the wa
ter had been lowered to the 800-foot
tunnel level. At this point two Of the
Gould triplex station pumps were in
stalled and raised the water handled
by the sinker in the shaft to the tun-
15-foot intervals until the 1000 foot
level had been reached. Then the re-
naming two Goulds were installed
here and handled the water from the
lift of 400 feet to the tunnel level, Until
the 1900 was reached when the two
Goulds from the 500 level were lower
ed and installed at this point. In this
way pumping was a continuous opera
ton until the water was lowered to the
1900 level where the Riedler was in
stalled with motor drive, and raised
the water from the sinker to the tunnel
level, lift Of 1000 feet. The Gould
pumps were then placed on the 5000
and@2200 as they were reached, with
lifts of 200 and 400 feet respectively 10
the Riedler, which in turn lifted 1t to
the 600. On the 2200 permanent in
stallation was made of two Goulds,
electrically driven, and $50 gallon
auxiliary air driven Cameron for use
in case of interruption Of electric pow
er. There will also be made a similar
permanent installation on the 22O0 as
we'll as No 9 Cameron sinker in the
shaft at this point
! The bailers have capacity of 1000
gallons each and were hoisted in bal
ance by the steam hoist at the engine
station on the 500 level.
1 AT first two tanks per minute were
hoisted, but when greater depth was
reached this speed was necessarily d-
minished; final rate of tanks in 6
4 minutes was maintained.
Many Unforeseen Troubles.
1t is impossible in an article of this
nature to give full account Of all the
unforeseen difficulties which were en-
countered and which were overcome
only by means Of much thought, inge-
nuity and arduous work One of the
greatest sources of interference in the
operation of the bailers arose from the
timbers OF all description which had
found their way into the shaft. To re-
move these long poles with pronged
spear heads were used. The men soon
became very proficient in the use of
these from the shaft sets. A surpris-
ing amount of timber of all sizes and
descriptions were taken out of the
shaft in this manner.
! At many points in the shaft there
were sections Of the guilds missing on
one or both sides A simple method
OF replacing these was devised as fol-
lows The bailer was lowered to the
water level. A five or ten-foo Sec
tion as required, was removed from
the guide Immediately above and low
cred into the water and fastened al
the top with one lag screw, and the
part removed replaced. The guide
shoes on the tank and the top fasten-
ing were sufficient to secure a stable
guide until the water was lowered
enough to allow additional screws in
the next set. This eliminated all ty-
ing of guides with ropes and other in
secure methods.
The sinking pumps were supplied
with a 22-foot suction pipe and were
lowered at 15-foot intervals. They
were securely jacketed against the
wall plates in addition to the hang
ing support.
Signal System Working Force.
\ very complete signal system was
used. This consisted of flash signals
on each level entirely independent If
the engineer for ntercommunication
between levels; also electric bell
switches on each station. and a bell
cord the full depth of the shaft, direct
to the engineer A telephone was
placed on each level as 1t was reached.
The operating crew consisted Of he
following; one compressor engineer.
one fireman. two pumpmen, two shaft
men, hoist man and oiler, electrician
and helper, pipeman and helper, ma
chinist and helper blacksmith md
helper master mechanic. assistant.
shaft boss, yard boss, and four yard
men, office man, two watchmen and
crew of rope men when needed
An average Of thirty tons of COZ |
per day was used, which constituted !
one of the greatest cost items, the
cost of coal being over $500 laid down
at the mine.
The task was completed exactly :
