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

464 Keports of the Inspectors of Mines. [Off. Doc.
0. 1. C.—Was in bad condition when last visited, the ventilation being-
far below the requirements. There was no map of the working's pro-
vided and no leg-al mine-boss employed, but I am informed that they
have since had a complete survey made and are now sinking- a shaft for
a new furnace, which will be ready in a short time. They have also employed
a legal mine-boss. Air in circulation, about 5,000 feet per
minute.
Poioers.—Is in pretty good order. Quantity of air at the outlet when
last measured, 40,400 feet per minute, but a considerable quantity of
this is lost by leakag-e and does not pass to the face of the mine. At
the time of my last visit all parts of the mine were reasonably well ven-
tilated.
Federal Spring,—The ventilation at face of working-s not very brisk.
Average quantity of air at face of entries, 4,000 feet, and 12,000 feet per
minute at the outlet when last measured, but the mine was not working
steadily at that time and only a few miners were working. The furnace,
when fired properly, will produce from 18,000 to 20,000 feet per minute.
Beachnount.—Is in bad condition. The roadways are wet and muddy.
The doors which should be used to guide the air current to the working
places are not kept in good repair and are left open most of the time,
in fact there is very little evidence of skill or sound judgment being
used either inside or outside of this mine. Quantity of air at the outlet
when last measured, 25,200 feet per minute. This quantity is sufficient
if properly distributed to the workings, which I have reason to believe
is not done. Of course it is the old story we get when we make our com-
plaints, namely, that we always visit the mines when things are a little
out of place.
Federal.—On my last visit the room pillars w^ere not cut through as
often as required, and some of the entries were driven too far in advance
of the air current. Quantity of air in circulation, 30,000 feet per minute.
Mines on the Montour's Run and Bloon Run Railroad.
Beach Cliff and Montour Mines.—These mines when last visited were
in favorable condition. Quantity of air in circulation in the Cliff mine
25,000 cubic feet per minute, and 56,550 feet per minute in the Montour
mine. Both mines generate large quantities of black damp and require
a brisk air current to maintain a healthful atmosphere in the roadways
and working places ; in fact it is difficult at some periods during the
summer season to keep the Montour mine free of this noxious gas, notwithstanding
the large volume of air in circulation.
Moon Run.—This is a new operation, opened du)-ing the past year on
the Moon Run railroad, a branch about five miles in length, connecting
with the Lake Erie railroad, a short distance below Chartiors. The out-
side equipments at this mine are first class and present indications point
to a large production in the near future. The mine is located in the
