Mining & Extraction

Industry pages on PlainEmployers exist to answer one question that a single employer profile cannot: is what you are seeing at one company normal for its sector, or an outlier? Every figure below is computed from the same three federal datasets that power individual profiles, the Department of Labor H-1B disclosures, OSHA injury records, and state WARN Act notices, aggregated across every employer we map to this industry. Read the sector numbers first, then judge any one employer against them.

PlainEmployers tracks 908 distinct employers operating in the Mining & Extraction sector (NAICS prefix 21), each pulled from U.S. Department of Labor and OSHA public disclosures rather than self-reported corporate profiles. The median wage disclosed on H-1B visa petitions in this industry is $133,728, computed from individual position-level filings (which must meet or exceed the DOL-set prevailing wage). In aggregate, Mining & Extraction employers have filed 346 H-1B labor condition applications, averaging about 0 per employer.

On workplace safety, the Mining & Extraction peer group shows an average DART rate of 2.39 injuries per 100 full-time workers, a standardized OSHA metric counting days away, restricted duty, or job transfer from workplace injuries. That number is the benchmark every individual employer profile is scored against, so an employer with a DART of 3.5 against a 2.0 industry average is running roughly 75% above the norm. The metric self-corrects for company size, which is why it is more meaningful than raw injury counts: a 300,000-worker retailer and a 400-worker machine shop can be compared on equal footing, and industry-wide patterns (construction and warehousing skewing high, finance and professional services skewing low) are visible here.

Among the largest visa sponsors in Mining & Extraction currently indexed are Schlumberger Technology Corporation, Nevada Gold Mines LLC, ExxonMobil Technology and Engineering Company, each with a dedicated profile covering salary breakdowns, OSHA safety grade, and WARN Act layoff history. Jobseekers researching this sector should cross-reference the wage numbers here with metro-level pages, because H-1B wages are legally tied to the prevailing wage for the specific metro-occupation combination: a software engineer in San Francisco and one in Nashville show materially different disclosed salaries for the same role. The ETL pipeline re-pulls federal and state disclosures on a recurring schedule, so the employer list, wage figures, and safety benchmarks here refresh as new public filings are released.

Industry-level totals combine every employer record mapped to this sector, drawn from WARN Act notices and US Department of Labor filings. They are most useful for spotting trends and comparing sectors, and least useful for judging any single employer within the industry: a high sector total does not mean every firm is cutting jobs, and a low total does not rule out significant layoffs at individual companies. Where an employer spans multiple sectors it is assigned to its primary activity. Treat these aggregates as a starting point, then drill into the individual employer records and the source filings before drawing conclusions.
