Frequent rotation in the directional well forms a keyway, and the drill rod is stuck in the keyway. Preventive measures: Regularly perform short trips to repair the wellbore and control dogleg deviation..

Before drilling, inspect the condition and lubrication of all drill string components, including the hammer or drifter. Replace any worn out parts, following manufacturer’s recommended discard limits closely. Snake skin is a wear pattern of micro cracks that develop from drilling fatigue in non-abrasive rock..
This chapter contains some common types of failures occurring on DTH drilling tools For most failures we can identify it’s probable cause and typical supporting evidence.
Rod connection and removal are crucial aspects of down-the-hole drill operations, directly impacting overall work efficiency and the service life of rock drilling tools..
It was possible that the rig was drilling in severe drilling conditions, or that the driller was pushing too hard or had a poor drill string design. I asked some questions as to hole sizes, depths, etc.
[pdf] Are holes marked and have you a suitable drill log sheet? Are the holes properly sealed by the rubber skirt? Is the dust extraction equipment fully operational? Are there any obvious signs of cracks, overhangs on/behind the face? Is the brake operational? Is your shelter up wind of the rig?
