Reports of the Inspectors of Mines of the anthracite and bituminous ...

No. 12.] Seventh Bituminous District. 463
there being- very little air passing- throug-h the entry where most of the
men were working-. On my last visit there was a g-reat improvement^
but there were still two or three places working- too far in advance of the
air current. Quantity of air passing- into the mine, 9,600 feet per minute.
Boon.—General condition is favorable. They have put a larg-e quan-
tity of cribbing- and new timbers in the pit mouth, and for a consider,
able distance along- the main entry, which has very much improved the
main hauling-way both as regards convenience and safety. Quantity of
air in circulation when last measured, 25,000 feet per minute.
Allison.—This mine is now operated by J. V. H. Cook & Son. On
my first visit the ventilation in one part of the mine was very defective.
A number of men were turning- rooms in advance of the air current ; the
atmosphere being- foul and injurious to health. This was not the first
time that I have had reason to complain to this company in reg-ard to
the pernicious system of having- a number of men at work turning- rooms
where there was no air current in motion, but it seems to be an old habit
hard to be g-iven up. On my last visit matters were much improved,
but the ventilation was not distributed as well as it mig-ht have been.
Quantity of air at the outlet, 10,500 feet per minute.
Enterprise No. S.—In the first part of the year this mine was in very
bad condition, but it has since changed hands and the new company has
provided a fan and commenced to work the mine on a proper system.
They have also sunk a shaft for a traveling- way, tog-ether with several
other necessary improvements, costing- a considerable amount of money.
Previous to the chang-e in ownership the mine was without ventilation,
unhealthy and unfit for men to work in, but it was not often that a suffi-
cient number of men were employed to bring- it under the provisions of
the law. The mine at the present time is in a favorable condition and
will likely become a reasonably larg-e operation in the near future.
Quantity of air in circulation when last measured, 14,500 feet per minute.
nines on the P., C. & Y. R. R.
Essen.—The ventilation in this mine is now below the requirements.
It needs a larg-er fan, which the company has promised to provide in
the near future. Quantity of air at the inlets, 21,300 feet per minute,
but a larg-e quantity of this is leaking into the return airway and is of
very little benefit to the men.
Beadling.—ls in reasonable order, but they have a habit of sometimes
turning- rooms from the entries in advance of the air current. The en-
tries and working- places being- driven in the solid coal, g-enerate consid-
erable quantities of explosive g-as and requires close attention on the
part of the mine officials to prevent accidents. Quantity of air passingout
at the furnace when last measured, 35,000 feet per minute, which
were reasonably well distributed to the working-s.
