During rotary drilling rig construction, various problems often arise, and stuck drill bit is considered one of the most serious accidents in rotary drilling operations. When a stuck drill bit occurs during rotary drilling rig construction, it causes significant headaches. Today, Shandong Liqiang, a rotary drilling rig manufacturer, summarizes the causes of stuck drill bit incidents to help you avoid such accidents during your operations.#drilling machine application#
There are many reasons why a drill bit might get stuck. Let's analyze them one by one:#drilling machine application#
1. Drill rod jumping, falling rocks passing through rock strata changes, or falling alloy pillars can all cause the drill bit to get stuck.
2. Displacement of the drilling rig during rock drilling, or deviation of the drill bit in the borehole, can also cause the drill bit to get stuck.
3. Falling rocks from the borehole wall or opening during drilling, or encountering caves or large fissures, can also cause the drill bit to get stuck.
4. Prolonged stoppage without cleaning off dust or lifting the drill bit, resulting in the impactor being buried by rock dust, is another cause of stuck drill bits.
5. Broken drill bit blades or a new drill bit with a larger diameter than the original can also cause stuck drill bits.#drilling machine application#
