Bucket flaps should enter the hole when fully stretched.
The initial drilling can not be pressurized, then gradually pressurized after the backdrilling is stable. At this time, the core barrel should not appear to skipped(move up and down).
If countersinking or stuck drilling occurs during drilling, stop pressurizing and do not use reversed drilling.
During the drilling work, it was found that the slewing resistance suddenly increased. At this time, it can be preliminarily judged that the core has been broken, and it can be reversed 2 to 3 times, and the core barrel could be lifted.
