Exploratory drilling is conducted to investigate and evaluate mineral deposits and to assess geological and hydrogeological conditions. The drill cores and data from geophysical well logging support the planning of mining and infrastructure projects.

THYSSEN SCHACHTBAU performs directional drilling—including controlled vertical, inclined, and horizontal drilling—to precisely create defined borehole trajectories. Using steerable drilling assemblies (e.g., MUD motors, RVDS system) as well as MWD/LWD measurement, the borehole path is continuously monitored and actively corrected. Directional drilling is used, among other things, for drainage, injection, freezing, pilot, and exploratory drilling and enables high precision even under complex geological and hydrogeological conditions.

Raiseboring and slot-raising methods are used to create blind and through-holes, for example for shafts, conveyor systems, or ventilation structures. These methods are characterized by high-quality execution and controlled work processes.

Drilling for freezing and grouting operations is used to temporarily or permanently stabilize and seal rock formations. These operations are used, among other things, for dewatering, soil improvement, or to secure challenging construction sections.
