gen
Somerset County Mines.
"Krebs" is located at JJstie, about two nules north of the town of
Somerset. It is one of the largest collieries in the county, employing
119 men inside. The ventilation and drainage have been well taken
care of, but the capacity of the mine has been increased to such an
extent that the furnace is no longer adequate to do the work of ventilating.
I, therefore, expect to see a fan put in here very soon, as
those in charge have a desire to keep the mine up to the requirements
of the law in every detail.
"Ashland."—This colliery has not been operated very much during
the past year. I examined it twice, and each time found it in good
condition, both as regards ventilation and drainage.
"Stonycreek."—The draimage, ventilation and general condition of
this colliery are very satisfactory. Considerable trouble has been
experienced here by local swamps in the seam of coal, which entails
a great deal of expense in draining the water from the mine.
Scalp Level District.
There will be found below a brief description, based upon a recent
visit, of "'Eureka No. 30," a part of the extensive workings now being
developed by the Berwind-White Coal Mining Company, in the Scalp
Level coal field, Somerset county.
The mine is located about three-fourths of a mile southwest of Scalp
Level, and, like all the others which the Berwind-White Company is
opening in the field, is on the B, or Miller, seam of coal. The direction
of the main heading is south, twenty degrees west, and it will meet the
outcrop of the coal on Shade Creek, in a distance of about two miles.
This heading is driven fourteen feet in width, or wide enough for
two tracks—one for empty trips going in and the other for loaded
trips coming out.
On each side of the main heading is a parallel air
course, the air being split near the fan, one part going straight ahead
along one course, the other crossing over the main hauling road and
thence along the other parallel airway. At each pair of cross entries,
which are to be very long, there will be an overcast, giving each pair
a separate split of air.
The pillars between the main heading and the main airways will
be 35 feet, and those between the main airway and the first room off
the cross entry will be 125 feet on each side of the main heading.
Each cross heading is turned off on a regular curve, so that the motors
travel at as great a speed and with as little friction as possible. Cross
