Safety sources and definitions

MSHA Violations (issue date), Accidents (accident date), and Inspections (begin date). Snapshot 2026-10-18.

Counts describe published rows, including contractor records; accident records are not distinct incidents or numbers of people injured.

Zero means no matching records in the imported sources, not proof of no events. Historical coverage differs by source; absence before a source begins reporting is not a zero incident rate. Invalid or absent dates and records after the snapshot are excluded.

S&S means SIG_SUB=Y. Fatality records use DEGREE_INJURY_CD=01. Proposed penalties are not final assessed or paid amounts; missing dollar values are omitted.

Inspection hours are SUM_TOTAL_ON_SITE_HOURS attributed to the inspection start date, without supervisor/trainee hours. Missing hours are omitted; a started inspection may still be open.

Portfolio totals use current mine membership, including events before the current owner or operator's tenure.

CFR headings link to the current Title 30 index; they are not historical legal determinations.

EIA-923 · COAL RECEIPTS

Coal shipments and quality

Receipts reported by power plants and terminals, matched by MSHA mine ID.

REPORTED RECEIPTS · SHORT TONS—0 rows · 0 receiving plants

HEAT CONTENT · BTU/LB—Weighted by reported tons

SULFUR / ASH · % BY WEIGHT— / —Separate averages over measured receipts

DELIVERED COST · USD/TON—No price coverage

No receipts matched this mine in the selected period. EIA-923 does not cover all mine sales, exports or metallurgical coal shipments.

Delivered cost includes transport and is not mine revenue. Missing prices remain blank. * Fewer than three months are published in the selected quarter. Receipts reflect the months EIA has published; an unfinished quarter is not comparable with a full quarter. Portfolio matches use current ownership.

Coverage, sources and calculations

Reported coal receipts at EIA-923 power plants/terminals; this is not a census of mine shipments, exports or metallurgical sales.
Matches use only the published MSHA ID, normalized to seven digits. Unidentified mine origins remain in the source table but are not assigned to a mine.
Portfolio attribution uses current MSHA ownership, not ownership at the shipment date. Receipts and production can differ because of timing, stocks and coverage.
Quality means are weighted by positive reported tons with that measurement. Delivered cost uses only rows with published cost, positive heat and positive tons; missing/withheld costs are never zero-filled.
USD/ton = (cents/MMBtu ÷ 100) × MMBtu/ton. This is plant delivered cost, not mine sales price or revenue.
Receipt month is as published, including records supplied by annual respondents. Recent months are preliminary and subject to revision. Missing rows do not prove zero shipments.

Imported releases start 2008-01. This window includes 12 published months. EIA releases · Survey instructions

EIA ANNUAL COAL REPORT · 2024

Coal prices and estimated revenue

Annual county prices and a production-based allocation of county coal sales.

FOB PRICE BENCHMARK · USD/TON—Published county average

ESTIMATED SALES · SHORT TONS—Allocated from published county sales

ESTIMATED COAL REVENUE · USD—Covered mines only · not reported revenue

ANNUAL PRODUCTION COVERED0.0%0 of 1 producing annual mine records

The estimate assumes each eligible mine receives its county-average price and shares county sales in proportion to production. Actual sales and prices can differ substantially. Unavailable estimates are excluded; this is not a total for the whole portfolio. Annual price data uses a separate window from the MSHA charts.

Enlow Fork Mine3607416 · Washington, Pennsylvania	9,181,023	—	—	—	County sales or price not published1 eligible mines / 1 sales respondents

Method, assumptions and source records

This is an annual county-sales allocation, not reported mine or company revenue. Currency is nominal USD in the source year; quantities are short tons.
Mine share = same-year annual mine production / eligible same-county production. Estimated sales = published county sales × share. Estimated coal revenue = estimated sales × published county average FOB price.
The model assumes eligible mines share county sales in proportion to production and receive the county-average price. Matching mine counts is a check, not proof of identical respondents. Mine quality, contracts and sales timing can differ substantially. No statistical confidence interval is implied.
FOB excludes transport and insurance. EIA-923 delivered costs do not enter this model. No grade premium, state/national fallback, quarterly apportionment or carry-forward to a later year is applied.
Eligibility follows the source's production threshold and excludes preparation-only and refuse operations. Withheld values, inconsistent county counts and missing/ambiguous locations produce no estimate.
County sales are published in thousands of tons and prices to cents. Calculations retain precision, but the inputs are rounded and the allocation is approximate.
Portfolio attribution uses current MSHA ownership, not ownership during the sales year. Covered-mine sums exclude unavailable estimates and must not be read as whole-company revenue. Coverage denominators use the annual EIA mine-production release.

Sales-reporting threshold: 50,000 short tons per mine in 2024. Withheld sales or prices stay unavailable.

Sources and interpretation

Coal means use numeric concentrations from samples marked not voided, excluding control/invalid sample types and dates after the snapshot. Missing values remain null; reported zeroes remain zero.
Quarterly means describe available samples, not mine-wide or worker-average exposure. Quarters with no eligible measurements remain empty; the current quarter is partial.
Personal C/E is MSHA's published concentration-to-limit ratio. A value above 1 is not by itself a citation or a determination under the 2024 silica rule. Personal and area files do not publish a void-status field.
Area records include bulk-dust analyses and are kept separate from personal exposure results. Their concentration units are not specified in the source dictionary.
Missing samples do not establish safe conditions. Coal quartz percentage and concentration are separate measures. No compliance threshold is inferred for coal samples.
