Description
of Mines.
Inspector.
Mines Situated Along the Allegheny Valley Railroad, in Armstrong
and Clarion Counties.
There are ten mines located in this division of the district. The
Monarch mine has resumed operation after having been abandoned
for nearly three years. The Mahoning mine is practically not under
the regulation of the mining act at present, while the Hardscrabble
mine has not been in operation at all during the year. The other
mines of this division of the district have been doing a reasonably
good business, as no strikes among the miners along this railroad
have occurred during the year.
Glen.—A new drift opening has been made here, located farther to
the south of the old mine. All the miners w'ho were working in the
old mine have now^ been transferred to the new one. The main entry
has been driven through the front hill, thus making two openings.
Although the ventilating furnace had not yet been built at the date
of my last visit, a portion of the workings was reasonably well ventilated,
but the air current was not sufficient at the face of No. 1 butt
entry. The mine was well drained. The total volume of air in circulation
was about 5,400 cubic feet per minute. The mine is being
worked on the single entry plan.
Riverview.—A good business is being done at this mine at present.
The coal is brought from the interior workings of the mine to the
check house, a distance of 4,300 feet by the tail rope system of haulage.
The machinery in connection Avith this haulage plant is all of
a substantial character. During my last examination of this mine,
the ventilating fan was running at forty three revolutions per minute
and producing 2S,000 cubic feet of air, but more than one-half of this
(juantity was lost through leakage before it reached the face of the
workings; however, the mine was reasonably well ventilated. As
was stated in my last year's report, a considerable portion of the
workings of this mine are under water, but this will be remedied
in the near future, as the comi)any is having a water course
level driven, which will be 500 feet long, in the solid rock beneath
the coal seam, N\hich will coni]>l
