Title: Coal Mining in Pennsylvania


1
Coal Mining in Pennsylvania
  • Dylan Kevech
  • Jamie Finch
  • EGEE 211

The 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.
  •  Only used when drilling straight down is not
    possible.
  • Slope mines are not usually deep.     

This picture demonstrates a typical slope mine
with a shaft that is slanted to reach the coal
bed.

Bell 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.

Room 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.

Evolution 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.

Dangers 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

Child 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.

The 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

11
As 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.

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

Mine 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

However, this is not always the case!
