Mazier Core Barrel Drill for Medium-Soft Rock Formations
We will drill using mazier core barrel for 300 meter depth to get
the sample.
Core drilling will be combined with open hole.
The rock formation is medium-soft, and some layer easy to collaps.

The automatic Mazier core barrel is designed for obtaining
undisturbed core samples in soft soil by applying downward
pressure. The cutting shoe and connected inner barrel projects
ahead of the bit when drilling in soft materialand retracts when
the drilling pressure increases in harder materials. This greatly
reduces the possibility of drilling fluid coming into contact with
the core at the point of cutting.
The mazier core barrel has an inner plastic coreliner which
protects the sample during transportation to the laboratory. The 74
mm diameter core obtained with the mazier is compatible with the
commonly used laboratory triaxial testing apparatus.
Advantages:
. Undisturbed core samples from soft soil 0.1MPa
. Nil wall coefficient
