What the data says about Mining & Extraction

For Mining & Extraction (NAICS 21), PlainEmployers answers the sector-level question a single employer profile cannot: is what you see at one company normal for this industry, or an outlier? The figures below aggregate DOL H-1B disclosures, OSHA injury records, and WARN notices across 908 mapped employers and 346 H-1B filings at a $133,728 median disclosed wage. Read the sector numbers first, then judge any one employer against them.

Corpus placement: Mining & Extraction ranks #19 of 22 industries by total H-1B filings (about the 14th percentile). Largest indexed sponsors: Schlumberger Technology Corporation, Nevada Gold Mines LLC, ExxonMobil Technology and Engineering Company inside a 346-filing sector roster. Safety inventory: sector average DART is 1.06 across 8 employers with ITA rates; 8 employers carry both H-1B volume and a DART figure for the dual-axis chart below.

Mining & Extraction's 1.06 average DART is on the lower-injury side of the corpus; an employer well above that mark is a clearer outlier than the same rate would be in a high-DART sector.

Largest indexed sponsors in Mining & Extraction: Schlumberger Technology Corporation, Nevada Gold Mines LLC, ExxonMobil Technology and Engineering Company. Open each profile for salary mix, OSHA grade, and WARN history, then check the metro page for the same role, because prevailing wage is metro-occupation specific.

Mining & Extraction totals combine every employer mapped to this primary activity: a high sector total does not mean Schlumberger Technology Corporation or its peers are cutting jobs, and a low total does not rule out layoffs at individual firms. Multi-sector companies are counted once under their primary NAICS. Treat these aggregates as the starting yardstick, then drill into the individual employer records and source filings before drawing conclusions.

H-1B filing volume vs. OSHA safety rate in Mining & Extraction

Exploratory join of two independent federal populations for Mining & Extraction employers that have BOTH figures: DOL OFLC H-1B LCA filing counts (FY2024–FY2025 disclosure window) on X, and OSHA Injury Tracking Application DART rates (establishment calendar-year injury logs) on Y. These are not the same vintage or category set, the chart does not claim a causal ratio. A large H-1B sponsor is not automatically a riskier or safer workplace than a small one. 2×2 strategic matrix plotting 8 entities by H-1B filings (DOL OFLC) (X) and OSHA DART rate (ITA) (Y), with a crosshair dividing the plot into four quadrants.
