Challenges during Drilling Operations in Mines
It is almost certain that problems will occur while drilling. For example, in areas in which similar drilling practices are used, hole problems may have been reported where no such problems existed previously because formations are non-homogeneous. Therefore, two wells near each other may have totally different geological conditions. The most prevalent drilling problems include:
- Pipe sticking
- Loss of circulation
- Hole deviation
- Pipe failures
- Borehole instability
- Mud contamination
- Formation damage
- Hole cleaning
- H2S-bearing zones
- Shallow gas zones
- Equipment and personnel-related problems
Understanding and anticipating drilling problems, understanding their causes, and planning solutions are necessary for overall drill-cost control and for successfully reaching the target zone.
Mines and quarries increasingly need to produce more with less. Streamlining drill and blast routines can improve safety and productivity, and reduce operational costs.
The above-shown video is one of its trype. We had faced this circumstance in Moher and Moher Amlorhi Mines of Singrauli (Madhya Pradesh, India) in the year 2018.
