2The Process of Pennsylvania Coal Mining
Slope Mine
- Coal is too deep to allow surface mining.
- Coal is parallel to the ground.
- Called slope mine because shafts are slanted.
- Â Only used when drilling straight down is not
possible. - Slope mines are not usually deep.   Â
This picture demonstrates a typical slope mine
with a shaft that is slanted to reach the coal
bed.

3Bell Pit
Open Face Mining
- Used when other mining is impossible.
- Consists of straight shaft dug by hand.
- Miners are connected to a rope when in the mine.
This rope is also used to hoist miners and coal
upwards. - Usually very small and shallow. Miners can only
mine so much before the ground gives way.
- When a coal seam breaks through and is visible
through the ground. - One of the earliest forms of mining.
- Coal is harvested with picks and shovels.
- Least dangerous.
- Small quantities of coal.

4Room and Pillar
Long Wall Mining
- Rooms are cut into the coal seam 20ft wide
leaving pillars in-between the cuts. - Much coal is wasted in pillars.
- Many Irish immigrants were given the dangerous
job of robbing the pillars. - The pillars prevent much ground subsidence
- Continuous miner is used. No need for hundreds of
real miners - Leaves no support behind for coal that has been
removed. - Major cause of Land subsidence
- The most popular type of mining in use today.

5Evolution of Machinery
- First tools were a pick and a shovel
- Coal was drilled, then explosives were inserted
into the hole and blasted loose. - First I would drill a line of holes about three
feet apart and as deep as the drill bit would go,
the one I used was about 4 long. I would then
put in a ½ copper pipe and tamp clay around the
pipe leaving a small hole when I pull out the
tubing. I always used black blasting powder
because if I used dynamite I would have to wait
for all about an hour or two, if not it would
give you a headache. Blasting powder allowed you
to continue working as soon as the smoke cleared
and the dust settled. Next I would take the
squib, insert it into the hole with the powder
packed in. The last thing I would do is scream
fire and run as fast as I could. Then the hard
work started.- Frank Kevech Sr. - Under cutting machine

8Dangers of Coal Mining
- Collapse-Roof could Collapse because of poor
timbering. Slate could cause the coal face to
slide down on top of miners. - Mine Fires
- Centralia- Underground coal mine fire that has
been burning for many years. Many attempts to
stop the burning have failed. - In the Winter months, dry cold air enters the
mine and takes the moisture from the dust
creating a dangerous coal dust that could catch
fire.
- Flooding
- The Knox Mine disaster of 1959
- The Wyoming Valley in Luzerne County
- Miners went too far towards the Susquehanna River
and the river broke through - Train and mine cars were tossed into the river to
fill the hole. Finally plugged with cement and
stopped the water flow. - 12 Miners were killed in the accident

9Child Labor
- Children sometimes accompanied their Fathers into
the mine to help expedite work and increase
production. - Young Children were put to work as breaker boys,
brattice boys, spraggers, and runners - Children were paid very little for their work.
- Breaker Boys were beaten by breaker bosses.

10The Environmental Impact of Coal Mining in
Pennsylvania
- Longwall mining has caused severe damage
especially near my hometown. - Loss of water
- Loss of Homes
- Destruction of Property
11As the longwall machine extracts the coal and
moves forward, the machine leaves nothing behind
to support the ground. Therefore the land falls
in to fill the void.
- Resulting in
- Loss of water to house
- Loss of water for farm animals
With this loss people have to resort to using
water buffalos. These water buffalos dot the
hillsides in mining communities.

12Destruction and Loss of Homes
Mining causes homes to subside which causes
people to move and relocate from the area in
which they grew up.

14Acid Mine Drainage
15Mine Reclamation
Mine Companies are supposed to go back after
they are all done mining and fix the area so that
it is able to be used in the future www.lr
