Daily Maintenance of Mining Drilling Rigs

Inspect the drilling rig frame, slide rails, and drill boom for deformation, cracks, or weld failures; ensure all mounting bolts are present and securely tightened. Verify that the drill rods and drill bits are in good condition, with no excessive bending, wear, or chipping, and that the rod threads are intact and free of stripped threads. Check that the hydraulic system has an adequate oil level, that hydraulic hoses, fittings, and cylinders are leak‑free, and that the filter elements are clean and unobstructed. Confirm that the thrust cylinder, rotary mechanism, and feed chain/rail are well lubricated and operate smoothly. Ensure that the water and air supply lines are intact, with valves that open and close freely and no leaks. Inspect the electrical system to confirm that wiring is undamaged, connections are secure, explosion‑proof equipment is in proper working order, and control buttons and instruments are responsive and accurate. Finally, verify that all protective guards and safety barriers are present and in good condition.

During drilling operations, monitor the rotary speed and thrust pressure to ensure they remain stable, with no jamming, vibration, or unusual noises. Regularly inspect drill‑rod connections to confirm they are secure, free from loosening or disengagement, thereby preventing rod breakage or loss. Monitor hydraulic oil temperature and system pressure to ensure they are within normal limits, avoiding overpressure or overheating. Verify that the water‑cooling system is functioning properly, providing adequate cooling to the drill bit, and prevent dry drilling or overheating that could lead to damage. If, during operation, you detect abnormal pressure, unusual noises, leaks, or severe drill‑tool vibration, immediately shut down the equipment and conduct a thorough inspection.

Clean rock dust, mud, and debris from the drill rig’s body, slide rails, boom, and all mechanical joints to keep the equipment tidy. Lubricate the slide rails, chains, rotary bearings, and all pivot points with grease or lubricant. Flush and clean the water‑supply filters and nozzles to prevent clogging. Inspect drilling tools for wear; promptly replace any bits or drill rods that exceed wear limits or are damaged, and store them separately by type. Tighten any loose bolts and pipe clamps on the entire machine, and check for potential risks of aging or leakage in hydraulic lines. Retract the boom and drill rods, return the equipment to its designated location, disconnect water, air, and power supplies, and implement proper dust‑proofing measures.
