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.
