Title: SAFETY IN MINING


1
SAFETY IN MINING
  • 100 Years of Progress

2
Mine Safety Legislation
  • Many of us have a tendency to resent what we
    perceive as unwarranted government interference
    in our lives.
  • We may even resent laws and regulations that are
    designed to keep us safe.
  • However, before we condemn the Mine Safety and
    Health Act of 1977, lets take a look back at an
    unregulated mining industry.

3
In The Beginning
  • As early as 1865 a
  • bill was introduced
  • to create a Federal
  • Mining Bureau. It
  • did not pass.
  • Little was done until
  • a series of disasters
  • occurred after the
  • turn of the century.

4
Open Flame Lights
  • The early miners light was a teapot shaped lamp
    that featured a rope wick encased in a long spout.

5
The lamp burned whale oil, which was poured into
the pot through an opening at the top.
6
Filled with oil and ready to be lit, the lamp was
placed on the hat.
7
The miner was now ready to enter the mine.
8
The oil lamp was replaced by the carbide light.
9
The bottom half of the light was filled with
carbide, the top with water. Turning the lever
permitted water to drip onto the carbide. This
combination produced acetylene gas.
10
The gas was ignited by a flint wheel and produced
an acetylene flame about 1 inch in length.
11
Carbide Light
  • Although it improved visibility in the mine, the
    carbide light was every bit as dangerous to use
    as the oil lamp.

Time Line - 1891
  • The first Federal mine safety statute became law
    in 1891.
  • Its provisions covered underground coal mine
    ventilation and barred mine operators from
    employing children under the age of 12 in
    underground mines.

18
The laws impact was negligible.
19
Coal was processed for market in Breakers.
There it was sized and the impurities removed.
20
Much of the physical work in the Breaker was
performed by boys between the ages of 8 and 12.
21
Breaker Boys
  • The Breaker Boys were responsible for picking
    the slate from the coal.
  • They were aligned in rows across chutes of moving
    coal and sat hunched there for hours.
  • They worked 9 10 hour days under very difficult
    conditions.

22
Some breakers employed as many as 200 boys.
23
They faced a seemingly endless supply of coal.
24
The conditions they worked under were deplorable.
  • The dust and noise were beyond imagination.
  • They suffered through the heat of summer and the
    cold of winter.
  • The boys worked under the watchful eye of the
    breaker boss, whose ready stick was available to
    unplug chutes and administer discipline.

26
There were no social supports during the early
1900s.
  • There was no Social Security.
  • There was no Workers Compensation.
  • Miners unable to work were left to fend on their
    own.
  • Some found work back in the Breaker.
  • A labor contract from the early 1900s contained
    the job title Boys, Old Men Cripples.

27
Many careers started ended in the breaker.
28
Door Boys
  • From all accounts the boys looked forward to
    their 12th birthday and the transfer it brought
    to a position underground.
  • They were assigned to strategic locations and
    were responsible for opening closing
    ventilation doors.

29
The working conditions and job duties of the door
boys were an improvement over work in the Breaker.
30
When the door boy heard a trip approaching he
would open the door and permit them to pass.
31
Drivers
  • By the time they were 14 most boys were promoted
    to driver.
  • They would deliver empty ore cars to the miners
    and pull out the loaded ones.

32
  • When a boy could handle one mule, he was given
    another.
  • When he could handle two, he was given a third,
    and so forth until he could drive six mules.
  • The ability to handle six mules resulted in adult
    wages.

33
Time Line 1900 - 1910
  • Roof falls, haulage accidents, and explosions
    killed thousands of miners.
  • The deadliest year was 1907 when 3,242 miners
    perished.

34
Monongah - 1907
  • The Monongah Mine of the Fairmont Mining Company
    was a state of the art operation.
  • It used electrical power, rather than animal
    power for haulage.
  • The 368 miners and their families lived in the
    town of Monongah.

35
In December, 1907, the mine exploded.
36
Rescuers found nothing but devastation and dead
miners.
37
Monongah
  • 363 miners were killed in the Monongah explosion.
  • It was the deadliest mining accident in U.S.
    history.

38
Monongah
  • The town of Monongah was instantly transformed
    into a community of widows, orphans and dead men.

39
1900 1910 Mining Deaths
  • COAL
  • 24,226
  • METAL/NONMETAL
  • ??

40
Time Line - 1910
  • In 1910 Congress established the Bureau of Mines.
  • Dr. Joseph Holmes was named Director of Mines.

41
Time Line 1911 - 1940
  • The role of Federal inspectors was largely
    limited to rescue operations.
  • To facilitate rescue efforts Dr. Holmes ordered
    eight specially designed rail cars.
  • The cars, supplied with first aid and mine rescue
    equipment, were placed at strategic locations in
    the mining regions.

42
When disasters occurred the nearest car was
rushed to the scene.
43
Since all mining operations had rail access, the
cars could travel to the scene of any mining
disaster.
44
First Aid and Mine Rescue Training
  • In addition to their work in disasters, the
    Bureau of Mines cars doubled as roving classrooms.

45
Thousands of miners were provided with first aid
training.
46
Rescuers
  • Special teams were trained in mine rescue
    techniques, including the use of breathing
    apparatus.

47
The equipment used by rescue teams was often
primitive and provided limited protection.
48
Rescuers
  • Tragically, many rescuers, including those from
    the Bureau of Mines, were killed in rescue
    attempts.

49
Bureau of Mines
  • Despite the best efforts of Dr. Holmes and his
    staff, mining disasters continued to claim lives.
  • Headlines such as these were all to frequent.

50
Haulage accident 9 killed.
51
Federal 97 Dead
52
Tonopah
  • Fire and explosion.

53
  • Bureau of Mines rescuers prepare to enter the
    Barrackville Mine 1916.

56
Time Line - 1941
  • Congress passed the Coal Mine Health and Safety
    Act a year after 257 miners die in four separate

    but no safety or health regulations are mandated.
  • The law expired after one year.

57
Time Line 1947 thru 1951
  • The 1947 Centralia explosion claims 111 victims
    just before Christmas, 1951, 119 die in an
    explosion.
  • Federal inspectors can notify mine operators of
    violations, but there are no enforcement
    provisions.

58
Centralia 111 Dead
  • State mine inspectors warned of the dry and dusty
    conditions 3 times in the four months preceding
    the explosion.
  • Rescuers were able to bring out 8 survivors, but
    one later died.

59

60
Time Line - 1952
  • Congress passes the Federal Coal Mine Safety Act.
  • Underground coal mines are to be inspected
    yearly. Surface mines and operations with less
    than 15 employees are exempted.
  • Federal inspectors have authority to issue
    withdrawal orders and notices of violations.

61
1951 1965 Mining Deaths
  • COAL
  • 5,880
  • METAL/NONMETAL

62
In 1965 the Pennsylvania Legislature made it
illegal to stable mules underground.
63

  • The 1952 Act is amended. Congress passes the
    Federal Metal and Nonmetallic Mine Safety Act.
  • Coverage is extended to small underground coal
    mines.
  • The law expands the scope of education and

  • The law included a training grant program.

65
Time Line 1972 - 1976
  • Ninety one miners die in a fire in 1972 at the
    Sunshine Mine at Kellogg, Idaho.
  • In 1976, a pair of explosions at the Scotia Mine
    in Kentucky kill 26 people.

66
The lack of effective evacuation sealed the fate
of the Sunshine miners.
67
Rescuers discovered 36 bodies on the hoist room
floor.
68
