The mining industry often displays its ability to shock with
deadly accidents such as the burst dam that has left hundreds
missing in Brazil, but fatal mishaps in the sector have declined in
recent decades.
Tighter regulations, technology improvements and automation that
have led to fewer people working in mines are behind the falling
number of mining fatalities, according to data from government
agencies and industry groups.
In 1950 there were 807 deaths in the U.S., which had fallen to
510 by 1960, 425 by 1970 and 27 last year, according to data from
the National Mining Association.
The 27 large mining companies, including Vale, that are members
of trade body the International Council on Mining and Metals
reported 51 fatalities in 2017, down from 63 in 2016.
Yet deaths remain higher in parts of the developing world, where
technology can be less up-to-date and regulatory oversight can be
weaker.
Death tolls are particularly high in some developing countries
in coal mining and through tailings dams, which collect mining
waste. A tailings dam owned by mining giant Vale SA burst Friday,
releasing mining waste and flooding the company's offices with mud.
At least 60 people were confirmed dead and 292 people unaccounted
for as of Monday morning.
In addition, available data doesn't give a definitive picture,
given many countries don't produce it and some of those that do,
such as China, may not provide a full account, experts say.
One factor behind the shrinking number of global fatalities is a
drop in the number of people working in the mining sector around
the world. "There has a been steady reduction in mine fatalities,
but there has also been a reduction on the amount of hours worked,"
said Rod Breland, an expert in mine safety at RMB Consulting
Services, Inc.
In the U.S., employment in mining and quarrying decreased 14% to
180,338 in the decade to January 2018.
In more recent years, the number of deaths has settled on a
relative plateau in the U.S. and European Union. In the U.S., 27
people died in mining accidents last year, 28 the year before and
25 in 2016, according to the U.S. Department of Labor.
Those tallies are far lower than early last century, when deaths
in the U.S. numbered more than 1,000 each year in coal mining
alone, peaking in 1907 when there were an estimated 3,242
fatalities in this sector, according to the Labor Department.
In the EU, there were 67 deaths in 2016, the most recent data,
down from 82 in 2010, according to Eurostat. The number of
fatalities had increased by one each year in the three years before
that, 2012 to 2015.
In South Africa, a total of 88 fatalities were reported in 2017,
and 73 in 2016, according to the Minerals Council of South Africa.
That 17% increase was the first rise in 10 years.
Few mines have been responsible for as many deaths as those in
the Chinese coal industry in recent decades. In 2002, 6,995 people
died in coal mines, according to a government paper. By 2017 that
had fallen to 375, according to the official Xinhua News
Agency.
Coal mining remains among the most deadly, often because
companies have to dig deep underground to mine. Underground mining,
as opposed to open-pit mining, brings the risk of gas and of mine
collapse.
That difference can be seen by comparing America's two largest
coal-producing states. Wyoming often produces over three times more
coal than West Virginia, yet over the last two years there has been
one death in the state compared with 12 in West Virginia, according
to government data.
Coal is mined from open pits in Wyoming and mainly underground
in West Virginia, according to the United Mine Workers of
America.
As with Vale, tailings dams have also been responsible for
casualties and accidents.
There were 39 tailings dam failures between 2007 and 2017,
according to research from the United Nations Environment Program.
Three of those were in Brazil, including a 2015 disaster at a mine
co-owned by Vale, which killed 19 people.
The increasing number and size of tailings dams around the world
magnifies the risks from them, according to a 2017 report by the
U.N. body and Norwegian environment group GRID-Arendal.
