Mining history

Every safety rule you have ever been trained on was paid for.

Mining is the oldest industry on earth and the one that took the longest to decide that the people inside it mattered. This is the whole arc — ochre pits, Roman hydraulics, breaker boys, Courrières, Farmington, the Mine Act — and what it cost to get from one end to the other.

The long arc

Forty thousand years of digging, and one question that keeps coming back.

c. 43,000 BC

The first mine was a paint factory

The oldest known mine on earth is the Ngwenya iron-ore working in Eswatini, dug more than forty thousand years ago for ochre — red and yellow earth used for body paint, burial and ritual. Nobody was digging for metal. They were digging for color.

In Neolithic Britain, flint miners at Grime's Graves sank shafts twelve metres deep with antler picks and shoulder-blade shovels, then cut galleries sideways under the chalk. There were no props, no lamps, no ventilation, and no word for safety. There was only the seam and the people who wanted it.

The oldest known working is a hole in the ground made for something to believe in.

The children

Before anyone regulated the air underground, they regulated who was allowed to breathe it.

Children were not an accident of the industrial mine. They were part of the design. A trapper sat in the dark beside a ventilation door for twelve hours and pulled it open when a haul came through. Breaker boys picked slate out of coal on a moving belt with bare hands. Both jobs were cheap, and both were small enough to do in spaces an adult could not work in.

On 4 July 1838, water broke into the Huskar drift near Silkstone and drowned 26 children. Fifteen were boys, eleven were girls, and they ranged from seven to seventeen years old. The country had known, in an abstract way, that children were underground. What it had not done was read their testimony. The 1842 commission went and asked them.

The Mines Act that followed banned all females and boys under ten from working underground, and it was the first industrial mining law in the world. It left surface work untouched, set no hours, and was enforced by almost nobody — but it established a principle that holds today: the state has a say in who may enter a mine.

In the Pennsylvania anthracite fields the same argument ran seventy years late. Lewis Hine’s 1910 and 1911 photographs of breaker boys were taken specifically as evidence, and two Supreme Court rulings struck down federal child labor laws anyway, in 1918 and 1922. A real national floor did not arrive until 1938.

“I'm a trapper in the Gawber pit. It does not tire me, but I have to trap without a light and I'm scared. I go at four and sometimes half past three in the morning, and come out at five and half past. I never go to sleep.”

Sarah Gooder, aged 8, trapper

Children's Employment Commission (Ashley Commission) report, 1842

1838

Huskar Pit, Yorkshire

Water broke into a drift and drowned 26 children. Fifteen were boys, eleven were girls, and they ranged from seven to seventeen years old. The public reaction made the 1842 investigation politically unavoidable.

1842

The Act, and what it left out

The Mines Act banned all females and boys under ten from working underground. It said nothing about the surface: girls and small boys kept breaking, sorting and carrying coal above ground for decades.

1911

The breaker boys, Pennsylvania

In the anthracite fields, boys sat on boards over moving belts and picked slate out of the coal with bare hands for ten hours a day. Lewis Hine photographed them for the National Child Labor Committee in 1910 and 1911; the images were the evidence.

1938

A federal floor at last

Two Supreme Court decisions had already struck down federal child labor laws in 1918 and 1922. Real protection did not arrive until the Fair Labor Standards Act set age and hour limits in 1938.

This is not a closed chapter. An estimated 160 million children were in child labour in 2020, and small-scale mining remains one of the sectors where it is hardest to see and hardest to stop — in cobalt in the Democratic Republic of the Congo, in gold in Ghana and the Philippines, in mica in Madagascar and India.

The toll

The number gets better. The arithmetic behind it is still people.

American coal miners who died on the job in 1907

3,242 deaths among 680,492 miners. It is the worst year in MSHA's record.

1 in 7,800

The same risk in 2025

8 deaths among 62,246 coal miners. The improvement is real, and it is the whole argument for the last fifty years of regulation.

Of the world's fatal work injuries

Mining employs about 1% of the global workforce and absorbs roughly 8% of its fatal injuries, according to ILO figures.

The ledger

Every law on this page was written by a disaster.

Not one major mining regulation in the industrial world arrived because the industry decided it was time. They came in the year after a fire, an explosion, an inrush or a collapse, when the names were still in the newspaper. Here are the ones that changed the rules.

1838

26 dead

Huskar PitSilkstone, England

An inrush of water through a shallow working drowned 26 children, aged 7 to 17, who were underground in the middle of the day.

What changed · The 1842 Royal Commission and the Mines Act of 1842, which banned women and boys under ten from underground work.

1866

361 dead

Oaks CollieryBarnsley, England

A series of explosions in quick succession killed 334 men and boys; rescuers were among the dead.

What changed · Momentum for the Coal Mines Regulation Act of 1872: enforced ventilation, accurate mine plans and certified managers.

1906

1,099 dead

CourrièresPas-de-Calais, France

A coal dust explosion swept through the workings and the rescue effort took weeks. Thirteen miners were found alive after twenty days.

What changed · Europe's worst mining disaster. It forced coal dust control onto the statutory agenda across the continent.

1907

362 dead

Monongah Nos. 6 and 8Monongah, West Virginia

An explosion in one mine blew through to the other through connected workings. It left hundreds of widows and children in a company town.

What changed · Along with Cherry Mine in 1909, it produced the United States Bureau of Mines in 1910.

1909

259 dead

Cherry MineCherry, Illinois

A fire in a car of hay for the mule stables spread into the timbers. Twenty-one miners died in a sealed section; one group survived by building a brattice wall.

What changed · Illinois rewrote its mining code, and federal funding for mine rescue and research followed.

1913

439 dead

Universal Colliery, SenghenyddGlamorgan, Wales

A firedamp explosion at Britain's worst coal disaster. The inquiry was blunt about management and about the mine's history of violations.

What changed · A push for rescue stations, better lamp discipline and shot-firing rules across the British coalfields.

1914

189 dead

Hillcrest MineHillcrest, Alberta

A methane and coal dust explosion killed 189 of the 237 men underground that morning, including nearly every man in the town's immigrant community.

What changed · Canada's worst mining disaster. It tightened Alberta's inspection and ventilation requirements.

1942

1,549 dead

Benxihu CollieryBenxi, Liaoning, China

A coal dust explosion under Japanese occupation. Survivors reported that the surface sealed the pit to protect the mine while men were still alive inside.

What changed · The deadliest mining disaster in world history, and a permanent reference point in Chinese mine safety debates.

1968

78 dead

Farmington No. 9Farmington, West Virginia

An explosion at a large Consolidation Coal operation. Nineteen men were never recovered and the mine was sealed.

What changed · The Federal Coal Mine Health and Safety Act of 1969, the first American mining law with real enforcement power.

1975

372 dead

Chasnala CollieryDhanbad, India

Water and sludge from an adjacent abandoned working broke into the mine and flooded it.

What changed · India's worst coal disaster. It exposed how little was known about old, unmapped workings next to active ones.

1992

26 dead

Westray MinePlymouth, Nova Scotia

A methane explosion in a mine where management had overridden and concealed safety concerns. Twenty-six men died; 15 bodies were never recovered.

What changed · The Westray Bill (2004) made it possible to charge corporations and their directors criminally for workplace deaths in Canada.

2006

12 dead

Sago MineSago, West Virginia

A lightning strike is the likeliest ignition source for a methane explosion. One miner survived 41 hours in the dark behind a curtain.

What changed · The MINER Act of 2006: refuge chambers, two-way tracking, and sealed atmospheres that must be monitored.

2010

29 dead

Upper Big BranchMontcoal, West Virginia

A methane and coal dust explosion in a mine with a long record of violations and a pattern-of-violations notice. It was the worst American coal disaster in forty years.

What changed · MSHA impact inspections, a $209 million corporate settlement, and a criminal conviction of the mine's superintendent.

2014

301 dead

Soma mineSoma, Turkey

A fire spread through a coal mine during a shift of nearly 800 men. The company's own records showed the risks had been reported.

What changed · Turkey's worst mining disaster. Mass protests followed, and mine managers and executives were tried and convicted.

2019

270 dead

Brumadinho damMinas Gerais, Brazil

A Vale tailings dam collapsed above a company canteen and a village. It came three years after the Samarco dam failure killed 19.

What changed · Brazil banned upstream-raised tailings dams, and the industry's dam-safety standards became an international issue.

A selection. Death tolls are the official figures where governments published them.

The rulebook

From “nobody inspected anything” to a miner who can shut a section down.

1842Mines ActUnited Kingdom
Banned all females and boys under ten from underground work. The first industrial mining statute in the world, and it was about children.
1850Mines Inspection ActUnited Kingdom
Created a corps of government mine inspectors with the power to enter workings, the beginning of enforcement rather than inquiry.
1872Coal Mines Regulation ActUnited Kingdom
Required adequate ventilation, accurate plans of workings, controlled shot-firing, and certified mine managers.
1910Bureau of MinesUnited States
A federal research and rescue agency, created after Monongah and Cherry. It investigated and advised; it could not close a mine.
1952Federal Coal Mine Safety ActUnited States
Mandatory federal inspections for the largest underground coal mines, with a narrow list of withdrawal orders. Enforcement stayed weak.
1969Federal Coal Mine Health and Safety ActUnited States
Dust limits, mandatory inspections, civil penalties, and black lung compensation. Signed a year after Farmington.
1977Mine Safety and Health ActUnited States
Created MSHA and covered coal, metal and nonmetal mines under one law. Four inspections a year underground, two on the surface, plus miner rights and whistleblower protection.
2004Westray Bill (Bill C-45)Canada
Amended the Criminal Code so organizations and their senior officers can be held criminally liable for workplace deaths. Written after Westray.
2006MINER ActUnited States
Refuge chambers, wireless tracking, and monitored seals, all required within months of Sago.
2024Silica ruleUnited States
MSHA cut the quartz exposure limit to 50 micrograms per cubic metre, the first real change to the standard in decades, aimed at the disease that replaced black lung.

The rest of the world

Every mining country has a record. Every record has a reason.

Safety is not a national character trait. It is the sum of enforcement, geology, mine depth, the size of the informal workforce, and whether anyone is allowed to say no to a supervisor. The differences between these records are political, not moral.

CNRecord

China

The largest workforce, the largest toll

China produces about half the world's coal from thousands of mines. Official figures put mine deaths above 3,000 as recently as 2008; the number has fallen sharply as small illegal pits were shut, but it remains the highest national total on earth.

The challenge · Small and township mines, methane, and the gap between state-of-the-art operations and the rest.

INRecord

India

Coal fires that have burned for a century

The Jharia coalfield has been on fire underground since 1916, subsiding whole neighbourhoods and driving people out. Chasnala in 1975 killed at least 372 when water broke in from old workings.

The challenge · Illegal rat-hole mining, unmapped legacy workings, and a large informal workforce outside the inspection system.

TRRecord

Turkey

Soma, and a long record since

The Soma fire of 2014 killed 301 men, Turkey's worst mining disaster and one of Europe's worst in the postwar era. Successive Turkish disasters have tracked deaths per million tons well above major producers.

The challenge · Privatised mines, contract labour, and enforcement that has repeatedly failed after disasters.

ZARecord

South Africa

Deep gold, silica dust and a reckoning

The world's deepest mines sit in the Witwatersrand, where heat and rockbursts are routine. In 2012, police shot 34 striking miners at Marikana; 44 people died during that week. A 2018 class settlement worth about 5 billion rand went to gold miners with silicosis and tuberculosis.

The challenge · Silicosis and TB among former miners, migrant labour, and the legacy of hostel living.

CLRecord

Chile

The rescue that changed a regulator

In 2010, 33 men were trapped 700 metres underground at San José for 69 days and all came out. The rescue was a national project and a global broadcast, and it exposed a regulator that had been starved of capacity.

The challenge · Sernageomin was rebuilt and inspections increased; small and medium mines remained the hard part.

AURecord

Australia

A strong record, maintained on purpose

Australia runs one of the safest large mining industries in the world, with fatality rates among the lowest per hour worked. Beaconsfield in 2006 still trapped two men for 14 days and killed one.

The challenge · Contractors, and the fact that a good national average hides bad individual sites.

CARecord

Canada

Westray, and criminal liability

Canada's worst disaster, Hillcrest in 1914, killed 189. Westray in 1992 killed 26 and produced the Westray Bill, which allows corporations to be charged criminally for workplace deaths, a legal tool most countries still do not have.

The challenge · Jurisdiction is split by province, so a strong record in one province is not a national guarantee.

UARecord

Ukraine & Russia

Methane, and the mines that outlive their rules

Zasyadko in Ukraine killed 101 in 2007; Listvyazhnaya in Russia killed 51 in 2021 when smoke overwhelmed men and rescuers alike. Both were methane and coal dust events in deep, gassy mines.

The challenge · Aging infrastructure, subsidised uneconomic mines, and inspection systems under political pressure.

BRRecord

Brazil

When the disaster is above ground

Samarco in 2015 killed 19 and buried a village in iron-ore tailings; Brumadinho in 2019 killed 270 when a dam collapsed above a canteen. Neither was an underground accident, and both were entirely foreseeable.

The challenge · Tailings dam safety, and the distance between a corporate safety policy and a dam inspection.

Coming back up

The other half of the record: the ones who came out.

Mine rescue is a discipline built out of failures. Every chamber, every drill hole, every two-hour refuge and every mine rescue team exists because a previous attempt ran out of time, air or information.

69 days

San José mine, Chile

2010

Thirty-three men survived 17 days on two days' rations before a drill broke through, then waited another seven weeks while three rescue plans ran in parallel. All 33 came up through a 66-centimetre shaft.

77 hours

Quecreek mine, Pennsylvania

2002

Nine miners cut into an unmapped flooded working and were trapped in a pocket of air. Pumps and a rescue shaft drilled by a surface rig brought all nine out alive.

14 days

Beaconsfield mine, Tasmania

2006

Two men survived a rockfall in a cage 925 metres down, eating a single cereal bar a day, while rescuers cut a tunnel through rock by hand. One colleague died in the initial collapse.
