Job description
Each shift begins with safety checks on equipment and tests for methane gas before any drilling starts. Bolters then position bolting machines, drill holes at precisely specified spacing, and force bolts into place using the machine's hydraulic mechanism, pulling down any loose rock that can't be safely supported along the way. The work is tightly bound to the pace and safety discipline of the whole mining crew, since a properly bolted roof protects everyone working below it. Coal mining employment has fallen sharply nationwide, so this has become a narrow, geographically concentrated occupation, even though the skill remains highly valued wherever mining continues.
Pros
- Strong pay even at the entry level, starting well above $63k without a college degree
- Skilled, safety-critical underground work using specialized bolting machinery
- Team-based job site culture in a specialized trade
Cons
- Employment in this field is projected to shrink sharply over the next decade (-34.2%)
- A relatively small number of positions nationwide (around 100), a very narrow, geographically concentrated field
- Hazardous underground conditions including regular testing for dangerous methane gas buildup
A typical day
The mantrip carries the crew into the section before dawn's irrelevant — underground has no dawn — and the bolter's first duty is checking the roof and ribs of the working face, reading the strata for the sag and flake that warn before failure. The machine work is methodical: drill the hole, insert resin, spin the bolt to mix and anchor it, torque to spec, move forward — installing the steel pattern that holds the mountain's ceiling over every miner who follows. Ventilation checks and methane readings punctuate the cycle. A stretch of bad top mid-shift demands extra support and slower judgment, because the roof is the mine's most patient hazard. The shift ends with the section advanced and supported, and daylight a novelty again.
Tasks at the job
- Drill bolt holes into roofs at specified distances from ribs or adjacent bolts.
- Pull down loose rock that cannot be supported.
- Position bolting machines, and insert drill bits into chucks.
- Perform safety checks on equipment before operating.
- Perform tests to determine if methane gas is present.
- Force bolts into holes, using hydraulic mechanisms of self-propelled bolting machines.
Workplace & working conditions
Work happens indoors, though not always in a climate-controlled space, and most of the day is spent on your feet, and you work in close physical proximity to coworkers or the public for much of the shift. Noise levels can be distracting or uncomfortable. The role involves regular exposure to hazardous equipment or conditions and contaminants, and specialized protective equipment is standard.
The pace is often fast, with real time pressure to meet deadlines. You'll regularly deal with frustrated or upset people as part of the job, and almost all of the work is done as part of a team.
