Underground Coal Mining
Underground coal mines extract coal through shafts and tunnels, following seams, supporting roofs, ventilating gases, and hauling material to the surface. Specialists turn production targets into daily shift plans, monitor equipment and safety compliance, manage inventory of roof bolts and supplies, schedule maintenance, track coal quality and shipments, and maintain the extensive permitting and inspection paperwork required for each mine.
What makes this business different
- Continuous monitoring of methane, carbon monoxide, oxygen and dust levels with automatic shut-down triggers
- Roof and rib support using bolts, mesh and cribs that must be installed per engineered plans
- Permits, MSHA inspections, ventilation plans, dust control plans and emergency response plans that require frequent updates
- Heavy mobile equipment (shuttle cars, continuous miners, roof bolters, scoops) with daily pre-shift inspections and maintenance logs
- Coal quality sampling, preparation and loading for rail or truck transport
- Shift-based production with crew assignments, face advancement tracking and supply replenishment underground
- Emergency evacuation drills, refuge chamber checks and communication systems that must be tested regularly

Workflows
Daily shift and production planning
Starts when: End of previous shift and weekly planning meeting
- Pull remaining targets from the mine plan and current face position
- Assign crews to sections, equipment and tasks for the shift
- Calculate required supplies (roof bolts, timber, rock dust) for the advance
- Review ventilation and methane drainage status for each section
- Create shift task list with production and safety checkpoints
Watch for: Production cannot begin until ventilation is confirmed adequate; Roof conditions from prior shift must be assessed before new bolting
Pre-shift and on-shift safety examinations
Starts when: Beginning of each shift and every 8 hours underground
- Generate checklist for each examiner covering air quality, roof, ribs, belts and electrical equipment
- Record findings from on-shift inspections performed by certified examiners
- Flag any hazardous conditions and required corrective actions
- Track corrective action completion before production resumes
- Update the master examination log for regulatory review
Watch for: Examinations must be performed by certified mine officials; Methane levels above 1% or oxygen below 19.5% require immediate withdrawal
Equipment maintenance and inspection scheduling
Starts when: Daily pre-use, weekly and monthly schedules
- Pull scheduled maintenance from equipment list (continuous miners, roof bolters, haulage)
- Create daily pre-shift inspection forms for each piece of equipment
- Track hours and fluid levels reported by operators
- Draft work orders for repairs that require downtime
- Maintain history of parts replaced and failures
Watch for: All mobile equipment must pass pre-shift inspection before entering the mine; Certain repairs require trained personnel
Underground supply and inventory management
Starts when: Daily consumption and weekly reorder
- Calculate roof bolt, cable, rock dust and timber needs based on advance rate
- Subtract current underground and surface stock
- Draft replenishment orders for delivery to the mine portal
- Track usage per section and flag low par levels
- Schedule delivery and storage underground to active faces
Watch for: Roof bolt length and resin type must match seam height and geology; Rock dust must be kept at required percentages to inert coal dust
Coal quality sampling and shipment preparation
Starts when: Each shift and upon loading
- Record face samples and belt samples per requirements
- Draft chain-of-custody forms for lab analysis
- Compile quality reports (ash, sulfur, BTU, moisture)
- Match loaded tonnages to rail or truck schedules
- Prepare bills of lading and quality certifications for approval
Watch for: Quality parameters vary by customer contract; Sampling frequency is dictated by permit and contract
Permitting, inspection and compliance tracking
Starts when: Inspection due dates, quarterly and annually
- Track expiration dates for all mine permits, ventilation plan approvals and dust control plans
- Generate required monthly and quarterly reports on production, employment and safety
- Compile inspection findings and abatement documentation
- Maintain training records for all miners and examiners
- Prepare renewal packages with updated maps and plans
Watch for: Mine maps must be updated daily with advance and sealed areas; All submitted documents require mine operator sign-off

- Update ventilation map with current fan pressures and airway dimensions
- Model methane liberation based on tonnage and seam characteristics
- Draft adjustments to regulator and seal placements
- Schedule methane drainage borehole drilling
