Labor & Workplace · MSHA Part 50

Down the Mine

The factory floor answers to OSHA. The mine does not. Coal, metal, sand, and stone answer to MSHA, the one agency that counts both halves of the only ratio that matters - every injury and death, over the hours actually worked. That denominator is the whole point. Divide by hours and a shrinking industry can no longer pass off closed mines as safe ones, and a quarter century of falling body counts finally has to say which it was.

2.33 reportable injuries per 200,000 hours worked all US mining, 2025

The Rate, State by State

I · Near You

Start with the map the title promises. Each mining state is shaded by its injury rate - reportable injuries for every 200,000 hours worked, the “per 100 full-time miners” basis MSHA reports on. Because it is a rate and not a count, Appalachia’s handful of deep coal states burns darker than the sprawling open-pit West. The national rate sits near 2.3; the top of the ladder runs well above it. States with no material reportable mining are left blank, not zero.

Alabama: 2.6 injuries per 200k hours (Coal) Alaska: 2.0 injuries per 200k hours (Metal) Arizona: 2.5 injuries per 200k hours (Metal) Colorado: 2.2 injuries per 200k hours (Coal) Florida: 1.8 injuries per 200k hours (Stone) Georgia: 1.4 injuries per 200k hours (Nonmetal) Indiana: 2.3 injuries per 200k hours (Coal) Kansas: 2.3 injuries per 200k hours (Stone) Maine: 1.7 injuries per 200k hours (SandAndGravel) Massachusetts: 3.0 injuries per 200k hours (Stone) Minnesota: 2.2 injuries per 200k hours (Metal) New Jersey: 3.0 injuries per 200k hours (Stone) North Carolina: 1.5 injuries per 200k hours (Stone) North Dakota: 0.6 injuries per 200k hours (Coal) Oklahoma: 2.3 injuries per 200k hours (Stone) Pennsylvania: 3.0 injuries per 200k hours (Coal) South Dakota: 2.8 injuries per 200k hours (Stone) Texas: 1.4 injuries per 200k hours (Stone) Wyoming: 1.6 injuries per 200k hours (Coal) Connecticut: 0.7 injuries per 200k hours (Stone) Missouri: 2.4 injuries per 200k hours (Stone) West Virginia: 4.3 injuries per 200k hours (Coal) Illinois: 4.3 injuries per 200k hours (Coal) New Mexico: 1.9 injuries per 200k hours (Metal) Arkansas: 2.0 injuries per 200k hours (Stone) California: 1.7 injuries per 200k hours (SandAndGravel) Delaware: no material mining District of Columbia: no material mining Hawaii: 2.2 injuries per 200k hours (Stone) Iowa: 2.0 injuries per 200k hours (Stone) Kentucky: 3.5 injuries per 200k hours (Coal) Maryland: 2.3 injuries per 200k hours (Stone) Michigan: 2.3 injuries per 200k hours (Metal) Mississippi: 0.7 injuries per 200k hours (SandAndGravel) Montana: 2.6 injuries per 200k hours (Metal) New Hampshire: 2.6 injuries per 200k hours (SandAndGravel) New York: 2.2 injuries per 200k hours (Stone) Ohio: 2.0 injuries per 200k hours (Stone) Oregon: 2.6 injuries per 200k hours (Stone) Tennessee: 1.4 injuries per 200k hours (Stone) Utah: 2.5 injuries per 200k hours (Metal) Virginia: 2.4 injuries per 200k hours (Coal) Washington: 2.9 injuries per 200k hours (SandAndGravel) Wisconsin: 2.1 injuries per 200k hours (Stone) Nebraska: 3.3 injuries per 200k hours (Stone) South Carolina: 1.7 injuries per 200k hours (Stone) Idaho: 2.5 injuries per 200k hours (Metal) Nevada: 1.5 injuries per 200k hours (Metal) Vermont: 3.2 injuries per 200k hours (Stone) Louisiana: 2.1 injuries per 200k hours (Nonmetal) Rhode Island: 2.3 injuries per 200k hours (SandAndGravel)

Which Work Hurts Fastest

II · The Ledger

Not all mining is equally dangerous, and hours worked is what lets you say so. Rank each kind of work by injuries per 200,000 hours and the order is stark: underground coal, on a fraction of the industry’s hours, tops the ledger; sand and gravel move mountains of material at roughly half its rate. The bars share one scale, so length is the comparison; the vertical tick is the national average of 2.3. Every rung is coal or metal, tagged and labeled.

Danger Against Exposure

III · Rate vs Hours

The ledger ranked work by rate alone. Plot that rate against how much of the industry’s hours each kind of work actually burns, and a second truth appears. Underground coal sits high and far right - lethal per hour, yet a thin slice of the workforce. Sand, gravel, and crushed stone sit low and wide: a gentler rate spread across so many hours that the bubbles - sized by the deaths themselves - stay stubbornly large. Safe-looking work, done at that scale, still fills graves.

The Falling Body Count

IV · Year by Year

Annual mining deaths fell from 85 in 2000 to 33 in 2025, a 61% drop, and the line is real progress. But a raw count moves for two reasons at once: mines got safer, and mines closed. Read this curve, then hold the question - fewer miners, or safer mines? - until section VI settles it. The spikes carry names; the disasters marked here are matters of public record.

2006 Sago Mine explosion - 12 killed. A methane blast trapped 13 miners in West Virginia; only one survived.

2007 Crandall Canyon collapse - 9 killed. A Utah collapse killed six miners; three rescuers died in a second fall.

2010 Upper Big Branch - 29 killed. The deadliest US coal-mine disaster since 1970, in West Virginia.

The Coal Share Collapses

V · Who Is Still Dying

Split the falling toll into coal and everything else. In 2000 coal was 45% of mining deaths; by 2025 it was 24%. The coal band does not just shrink with the total - it caves in, as seams close and the workforce leaves. Metal and nonmetal mining, quarries and open pits, holds roughly level. The face of a mining death is changing from a collier to a truck driver at a limestone pit.

Fewer Miners, or Safer Mines?

VI · The Denominator

Here is the whole argument in two lines. Set both to 100 in 2000 and watch them part. Hours worked ended the period near 83 - the industry barely shrank. The injury rate fell to 36, less than half. If the falling toll were only a hollowing-out, the lines would travel together; they do not. The daylight between them is safety a raw death count can never show - mines that got measurably less dangerous per hour worked.

How Mining Kills

VII · Cause of Death

Ask what a mine disaster looks like and most people picture a roof caving or a methane blast. The classification of every fatality tells a duller, deadlier story: the machines. Powered haulage - trucks, conveyors, mobile equipment - and machinery together account for 51% of deaths, more than every collapse, explosion, and inundation combined. Modern mining kills the way heavy industry kills: someone caught by something moving.

What a Reportable Incident Costs

VIII · The Severity Ladder

Every chart so far has counted an injury as one thing. It is not. Of the roughly 5,609 reportable incidents in 2025, most cost days of work, a few hundred left a permanent disability, and (%) were fatal - the thin dark rung at the far left, the sliver this whole dashboard was built to keep in view. Severity is a ladder, and only the bottom of it makes the news.

Segments under 1% are drawn at a minimum width so they remain visible; the counts below are exact.

Methodology

X · Notes on the Data

The figures on this page are built to the shape of MSHA Part 50 (Accidents, Quarterly Employment/Production, Mines). MSHA - not OSHA - regulates every US mine under the Federal Mine Safety and Health Act, and mine operators must file a Form 7000-1 for each accident, injury, or illness, plus quarterly reports of hours worked and production. Those two streams are the whole basis of this dashboard: incidents over hours.

Why hours, not headcount

A raw death count falls when mines get safer and also when mines simply close. To separate the two, every rate here divides incidents by employee-hours worked and multiplies by 200,000 - the hours 100 miners work in a year. So “2.33 per 200,000 hours” reads as injuries per 100 full-time miners, comparable across a shrinking industry and between a deep coal seam and an open pit.

What's real

Every number on this page is now built from a Full ingest: real MSHA Part 50 bulk data, not a stand-in. They are badged Full in the masthead. The rate, the state map, the sector scatter, the coal-metal split, the cause-of-death ranking, and the severity ladder are all computed from real accident, employment, and production records - 273,607 accidents, 2.7 million mine-quarters, and 91,871 mines, covering 2000-2025. The landmark disasters annotated on the trend - Sago (2006), Crandall Canyon (2007), and Upper Big Branch (2010) - remain hand-curated matters of public record, layered on top of the real yearly totals around them. The download, the column schema, and the MINE_ID join are documented in the repo's HANDOFF.md and src/lib/source.ts.

How each chart is built

The state map is a five-class quantile choropleth on the injury rate. The sector scatter plots that rate against each kind of work’s share of national hours, with bubble area carrying span fatalities. The composition area splits the annual toll into coal and metal/nonmetal from the same yearly rows the trend line draws. The cause ranking rolls fatalities up by MSHA accident classification; “coal-linked” flags a hazard whose deaths fall mostly on coal mines. Every chart reads from one committed derived.json and is rendered to static SVG at build time - there is no client JavaScript on this page.

What you're not seeing

Contractors report separately, and small operators sometimes underreport low-severity injuries, so the true injury count is a floor, not a ceiling. Occupational illness with a long latency (black lung, silicosis) surfaces in the record years or decades after the exposure, so a single year understates the real toll of dust. Hours worked are self-reported by operators. And a state's rate reflects the mix of work done there - a state of open pits will read safer than a state of deep coal even if any single mine is no different.
