568 REPORT OF THE BUREAU OF MINES. Off. Doc.
ventilate the other part of the mine and as both fans will have separate
intake and return airways; this arrangement will likely be effectual
for some time to come.
At Summer Hill mine, a shaft has been sunk at the face of the workings.
A sixteen-foot Capel fan is being erected on top of this shaft,
which will also be used to ventilate Nixon and Leasdale mines. It is
expected that this fan will be ready for operation by the latter end
of March, after which I think there will be no cause for complaint
relative to the ventilation at these mines. A fan has been provided
at the Boon mine and a new furnace built at Allison and the condition
of both mines is now satisfactory.
The condition of the other mines in this part of the district is fairly
good, but not beyond improvement.
Mines Situated on the Moon Run and Montour Railroad West of the
Allegheny River.
There are twelve mines in this division of the district. At Moon
Run, arrangements are being made to erect a new fan to ventilate
No. 1 section of the workings, the furnace not having sufficient capacity
to produce the required air volume for the number of persons employed.
At the present time one fan and three furnaces are in use to
produce ventilation for the whole of the mine workings, which extend
over a large area of territory consisting of several independent openings.
The ventilation at the Margerum and Partridge mines is not up to
the requirements, but I have been notified by the General Superin
tendent that new ventilating appliances will be provided for them
at once.
A new ventilating furnace has been erected at Freeport mine.
They are now cleaning up and enlarging the main airway, and after
this is done I expect to find the sanitary condition of the mine satisfactory.
Faults and rock rolls are numerous, and the coal is low,
making it very difficult to maintain airways of sufficient area.
A new fan has been provided at Natrona No. 2 and the workings
are now well supplied with good sweeping air-currents.
There are eleven mines located on the P. C. & Y. R. R., two of
which have been opened during the past year; all of these mines are
in reasonably good condition excepting Harrison and O. I. C. At the
former the ventilation is rather slack, but they are now cleaning and
enlarging the main airways which will remedy the defect. At O. I. C.
a more powerful ventilator is required, which the manager has promised
to provide at once.
