How To Solve Drill Rod Jamming Faults

Drill rods in drilling rigs frequently jam due to the following reasons:

  • Excessive Dust Accumulation‌: Excessive dust in the working environment.
  • Prolonged Usage Duration‌: Failure to replace the drill rod as required.
  • Misaligned Bit Position‌: The drill bit position has deviated and has not been adjusted correctly.
  • Loose Drill Rods‌: Improperly secured rods tend to vibrate and jam.
  • Rock Cuttings Clogging‌: Drilling operations generate significant cuttings. Untimely removal leads to borehole blockages, hindering rod advancement.
  • Drill Rod Fracture‌: Substandard rod quality or extended service life increases fracture risk, causing jamming.

II. Solutions‌ For Drill Rod Jamming Faults

Countermeasures for rod jamming include:

  • Dust Removal‌: Thoroughly clean internal dust, especially around the bit and jammed rod sections. Always power off the equipment before cleaning.
  • Rod Replacement‌: If the jammed rod is irreparable, replace it with a new one.
  • Bit Realignment‌: For functional but mispositioned rods causing reduced drilling efficiency, readjust the bit to its precise position.
  • Rod Securement‌: Ensure rods are firmly fixed before operation to prevent vibration-induced jamming.
  • Timely Cuttings Removal‌: Continuously clear cuttings during drilling, particularly near the borehole end. Installing ‌water flushing systems‌ cleans borehole walls, preventing cumulative blockages.
  • Strict Quality Control‌: Prioritize high-quality rods and routinely inspect for deformation/excessive wear. Replace defective rods immediately to avoid fractures.
