Abstract (en)
A rotary motor drives the drilling rods (80) during a drilling operation. Stabilizing jacks (22) create a resultant coaxial to the axis of the drilling resources. The jacks are arranged to be mounted on an arm of a hydraulic mini-digger located at the extremity connected to a hydraulic source. The jacks are operated without the addition of an extra hydraulic unit.
