Jumbo Drill Rig Maintenance Checklist for Underground Mines

Underground jumbo drill rigs work in some of the harshest conditions in mining. A consistent drill rig maintenance routine catches problems early and keeps rigs drilling. Use this checklist as a starting point and adapt it to your manufacturer’s maintenance schedule.

Always follow the OEM service manual and your site’s safety procedures, including isolation and lockout/tagout, before carrying out maintenance.

Daily (Pre-Start) Checks

Hydraulics

• Check hydraulic oil level and look for leaks at hoses, fittings and cylinders
• Inspect hoses for rubbing, cuts or bulges

Booms and feeds

• Check the feed for play and inspect drifter slides and holders
• Inspect guards, including rollover check valve guards such as the ROLLSAFEGUARD

Drilling consumables

• Check bits, rods and shanks for wear
• Confirm flushing water supply and pressure

Safety systems

• Test emergency stops, lights and alarms
• Check fire suppression system indicators

Weekly Checks

• Grease points on booms, feeds and rotation units
• Inspect slide pieces and wear pads for thickness and cracking
• Check mounting bolts and pins for looseness
• Inspect electrical cables and hose reels

Periodic Service (Per OEM Hours)

• Change hydraulic, engine and gearbox oils and filters
• Service the rock drill according to the manufacturer’s schedule
• Check accumulator charge pressures
• Inspect the feed beam for wear and straightness

Keep the Right Spares on Hand
