Chapter Five: Coal and the Environment
air, the slightest spark from any electrical equipment can set off raging fires or outright
explosions.
North American coal mining has worked to reduce this and other risks. Geology
experts and mechanical, electronic, and chemical sensors monitor the tunnels and
coal faces for any slight shift in the surrounding rocks, “sniffing” for methane and
other gases, and constantly checking for air problems. Ventilation equipment, too,
is improving all the time. But, as with any heavy industry, from oil rig flare-ups to
chemical factory leaks, coal mining still suffers accidents.
The Future of Coal
Around the world, the pattern of energy sources and uses is changing fast. Many
nations are pushing toward more renewable energy, reduced greenhouse gases and
other toxic emissions, and less damage to the environment, wildlife, and human
health. Renewables also give energy security in that each nation provides for its own
needs, rather than buying energy from other countries, which can be affected by
global prices, trade bans, and even wars.
Coal’s supporters argue that this natural resource already gives North America
energy independence. It is plentiful and relatively cheap. Further, technologies are
being developed to make it less polluting as a burned fuel, so that modern mining
Mining Disasters
Few events grab the news more than coal mine fires, explosions, collapses,
and other accidents. These are a few significant ones:
• Canada’s worst single disaster was at the Hillcrest Mine, Alberta, in 1914,
when 189 workers died in an explosion.
• In 1992, 26 miners died in a methane explosion at the Westray Mine in
Plymouth, Nova Scotia—which had only opened the previous year.
• The deadliest event in the United States was at Monongah Mine, West
Virginia, in 1907. At least 360 miners were killed in a fireball due to burning
coal dust or methane. In 2010, 29 miners lost their lives at the Upper Big
Branch Mine in Montcoal, West Virginia. Again, a probable mix of coal dust
and methane caught fire and set off a series of explosions.
