Title: The Coal Industry


1
The Coal Industry
2
BEFORE THE INDUSTRIAL REVOLUTION
  • Before 1500 there was little use of coal as a
    fuel in Britain but in the 16th century some
    enterprising landowners began to exploit their
    land by mining
  • The north east quickly took the lead and the
    phrase 'carrying coals to Newcastle' (meaning
    transporting a product from a place of scarcity
    to a place of surplus) dates from this period.
    Newcastle's location on the coast was ideal for
    transport - coal cost much more to transport than
    to mine.
  • The domestic market in London grew rapidly.Coal
    from the North-East was known as Sea-Coal

Bell Pits and Adit Mines
  • After the surface seams had been worked the bell
    pit method was used when there was a fairly thick
    seam close to the ground, but it was wasteful in
    the amount of excavation needed for a relatively
    small amount of coal.
  • The Pit and adit method involved digging
    horizontally along a seam of coal, often starting
    from an outcrop on a hillside, with vertical
    shafts inserted every so often. Uncut coal
    pillars acted as supports.
  • Fires lit at the bottom of each alternate
    mineshaft (the upcast shaft) improved
    ventilation.
  • Deep mining was rare before the Industrial
    Revolution and there was little demand for coal.

Rising demand for Coal
  • Demand for coal greatly increased as a result of
    a number of factors-
  • Fuel for the boilers of the steam engine, itself
    used in a variety of roles. Also locomotives and
    steam ships
  • As a dye in the textile industry.
  • Growing domestic use by an increasing population,
    with peat less available.
  • Conversion to coke for smelting in the blast
    furnaces.
  • Coal gas, a bi-product, was used for street
    lighting in the 19th century.
  • In furnaces making pottery, bricks etc

5
Problems of Deep Mining
  • As more coal was required pits had to go deeper.
    As a result a number of problems had to be
    overcome-
  • Flooding Deep pits filled with water. There was
    no real practical solution to this until the
    invention of Thomas Newcomens Atmospheric Steam
    Pumping Engine
  • Pit props were used to prevent cave-ins


6
Ventilation
  • The problem of firedamp, a lethal inflammable
    mixture of methane and butane was a very serious
    one.
  • Another problem was chokedamp poisonous carbon
    monoxide
  • One solution was to send down a miner with a
    naked flame and if he didn't get blown up, then
    you knew that it was safe
  • Another was taking down a canary, whose sensitive
    lungs would lead to it fainting and indicate the
    existence of chokedamp
  • Small boys called trappers were used to open
    and close doors to control the circulation of air

7
The Miners Safety Lamp 1815
  • Sir Humphry Davy, a famous scientist, invented a
    safe lamp in 1815
  • At the same George Stephenson, a semi-literate
    coal worker from Newcastle also invented a safe
    lamp the Geordie Lamp
  • When used properly these inventions stopped the
    risk of explosions
  • In 1800 John Buddle devised the Exhaust Fan
    this helped to ventilated mines

8
Moving Coal
  • Moving coal from the seam to the surface was a
    very serious problem
  • It was a task performed by women and girls, who
    dragged and carried the coal

9
Steam Engines and Rails
  • James Watts rotary Steam Engine helped to solve
    the problem of getting coal and miners to the
    surface
  • Above and below ground iron railways were
    introduced to ease the movement of coal
  • Pit ponies were used above and below ground

10
CONCLUSIONS
  • British Coal production increased from 2 million
    tons in 1700 to 216 million tons in 1899
  • This was vital in allowing the Industrial
    Revolution to happen
  • Coal mining remained a very difficult and
    dangerous job
  • In 1842 a government report into coal mining
    shocked the nation
  • As a result women and children were banned from
    working below ground
