How To Solve Drill Rod Jamming Faults [ Top 6 Tips ]

During the operation of rock drills, drill rod jamming is a common and quickly solvable problem. Different solutions can be taken to address the cause of drill pipe jamming:

1. Excessive Dust Accumulation‌: Excessive dust in the working environment.

Solution: Thoroughly clean internal dust, especially around the bit and jammed rod sections. Always power off the equipment before cleaning.

2. Prolonged Usage Duration‌: Failure to replace the drill rod as required.

Solution: If the jammed rod is irreparable, replace it with a new one.

3. Misaligned Bit Position‌: The drill bit position has deviated and has not been adjusted correctly.

Solution: For functional but mispositioned rods causing reduced drilling efficiency, readjust the bit to its precise position.

4. Loose Drill Rods‌: Improperly secured rods tend to vibrate and jam.

Solution: Ensure rods are firmly fixed before operation to prevent vibration-induced jamming.

5. Rock Cuttings Clogging‌: Drilling operations generate significant cuttings. Untimely removal leads to borehole blockages, hindering rod advancement.

Solution: Continuously clear cuttings during drilling, particularly near the borehole end. Installing ‌water flushing systems‌ cleans borehole walls, preventing cumulative blockages.

6. Drill Rod Fracture‌: Substandard rod quality or extended service life increases fracture risk, causing jamming.

Solution: Prioritize high-quality rods and routinely inspect for deformation/excessive wear. Replace defective rods immediately to avoid fractures.

Rock drill rod jamming is a common problem in rock drilling operations, and there are various solutions available. When using a rock drill, operators should pay attention to the fixation, cleaning, and maintenance of the drill rod, quickly solve the problem of drill rod jamming, and improve work efficiency.
