Drilling holes for various purposes - from surface and from headings

- vertical, horizontal and directional drilling,

- drilling wells including all installations,

- drilling reconnaissance and exploration holes with full coring, borehole tests and laboratory examinations

- drilling engineering holes for drainage, ventilation, backfilling etc.,

- drilling large-diameter holes (up to a diameter of 2.0 m),

- liquidation of drilling holes.

Depending on geological, hydrogeological and technical conditions the drilling work is done using the following methods:

- rotary drilling with normal circulation of drilling fluid,

- rotary drilling with reverse circulation of drilling fluid – down-the-hole hammer.

The drilling machines enable making holes from the surface to a depth of up to 2000 m and from mine heading with a diameter of up to 2000 m.
