No. 10. SIXTH BITUMINOUS DISTRICT. 383
"Soumaii ]S^o. 1" is one of the oldest mines in the district, and
will soon be worked out. There has been trouble at this place all
along on account of ventilation, as there is with all mines which were
opened up on the single healing plan, but I found, on my last visit,
quite an improvement in both the ventilation and drainage, and am
satisfied that the present plans will enable those in charge to keep
the mine up to the standard. On my last visit, I measured 15,U0U
feet of air at the inlet and about 8,000 feet at the extreme face of the
mine.
"Sonman Shaft."—The drainage, ventilation and general conditions
of this mine are good. Each section of work has its own split of air
and a back heading on the lower side of each hauling road, into which
the water is conducted, thereby making all hauling roads perfectly
dry. Haulage is by machinery, and the power used for pumping
is compressed air.
Lilly District.
Four mines are located at this point, namely: "Sonman No. 2,"
''Bear Rock," "Lilly Slope" and "Standard." The two latter are connected
and ventilated by one fan, set at the "Lilly slope" side. The
general condition of these two mines is very satisfactory in every respect,
the air and water being so conducted as to insure health and
comfort to the employes.
The "Bear Rock" is a small operation, with two drift openings, and
is
ventilated by a small fire-place, called a furnace, but hardly sufficient
to give good ventilation to the mine, although about thirty-five
men only are employed.
"Sonman No. 2" is also an old mine, but those in charge are now
opening up another section, cutting off the old part entireh^ and drawing
out all the pillars and stumps for the purpose of abandoning it.
The new section is being opened on the most im])roved plans of
mining, the ventilation being good, but defective in the old section of
the mine.
"Cresson Shaft" is the only mine located at this point.
The depth
is about .'>0(l feet to the first seam of coal in the upper coal measure,
called locally the Lemon, or geologically, the E, bed. The ventilation
and drainage, when examined last, were found to b(^ in a fair condition.
Gallitzin District.
Two mines are located at this point—the "GallKzin Shaft" and
"(iallitx.in Slope." The laltcr is (piilc a lai'ge i>lant, Itcing oitened up
in two sections—north and south. From the latter the coal is hauled
and mined by electricity. On the north side, coal is hauled by rope,
and the mining is done by machinery driven by electricity. The ventilation,
drainage and general conditions of the mine are very satisfac
tory.
