The Ely miner. [volume] (Ely, Minn.) 1895-1986, 1899-03-29

TO the several switches where chutes
are being used in the stiblevel. These
empties are being filed by the tram
mers at the chuJes, caves or drifts,
and then replaced on their switches,
whence the mule hauis them to the
shaft. In this way we avoid firing
our men by walking or pushing cars
for any considerable distance We
try TO cut down our grade as near as
possible TO one foot to 100 feet where
Training is done. Six inches TO 100
feet is sufficient grade aud will be es-
tablished by US in the future.
Our hosting is done On the vertical
by cage and on the incline by skips;
by high pressure engines and without
balance. We have at times three TO
four levels to hoist from. Mules ham
die our ore on the surface. The ore
on reaching the surface dumps auto
maticallY from the skip into car to
which a mule is attached, or il a
cage the mule is hitched directly to
the mine car. These cars are tram
med or hauled to the stock pile.
Empty cars, in both cases follow the
full one into the place il formerly
occupied. This is done by means of a
system OF tracks running through and
beyond the shaft house, doing away
with the turn table and the transfer
car or truck. A load for a mule on
the stockpile is two to three two-ton
cars. In the mine We endeayor TO
concentrate our men; working them
in certain section and giving a
foreman charge Of each gang OF men,
to see that they do a fair days work
and at the same time to protect them
from danger. There are not more
than 10 per cent OF our men who
speak the English language, and not
more than the above number who
have the remotest idea of mining.
We do not allow any foreman TO have
charge of more than Is men.
All ore mined on the seventh level
As above is dumped down the old No.
4 shaft, which is used for that pur-
pose as a pocket. 1t is taken out on
the eighth level and trammed to No.
4 shaft, 300 feet distant to the north.
All ore below the eighth level is also
dumped down No. 4 shaft or pocket
to the thirteenth level. 10 feet below
the eighth level and taken TO No. 5
shaft and hoisted. No. pocket has
three compartments, for first and
second grade ore and rock. Our No.
2 and No, 3 shafts hoist from the
seventh and eighth levels and will
eventually hoist from the thirteenth.
Below the eighth level we open
what is termed in this mine ''main
sublevels, p feet from bottom to
bottom. These levels are known as
the 9Th, 10th, 18th and 18th mainsub-
levels. The drifts are opened directly
under the main eighth level drifts.
The thirteenth level is opened some
what differently owing TO the pitch
OF the ore body. In opening up our
main framing level, we have rock
drifts of considerable length from the
ore body TO each shaft.
To No, shaft, $40 feet: TO No. 3
shaft, $50 feet: TO No. 2 shaft, 265
These rock drifts are usually tim
bered and will measure at least 10
feet in clear or inside the timber. In
mining our ore. We encounter much
rock and clay in the form of horses,
seams and punches. This necessi-
tates careful mining and much rock
picking to keep the ore up to grade.
On a basis of 100000 tons OF ore
mined, we will hoist about Is, 900 tons
of rock, two-thirds of which actually
comes from the ore body and one
third from the rock drifts, shafts,
raises, etc.
