specialized mobile hoist emergency service, high-altitude rescue, work at height, climbing techniques, specialist rescue teams

The paper presents the organization and operation of the specialized mobile hoist emergency service of the Mining Rescue Unit of CSRG S.A. in Bytom. As part of this rescue service, a high-altitude rescue group, trained and adequately equipped to use climbing techniques in life-saving work and removal of energy-machine failures in mine shafts and sub-shafts, was presented. Specialized equipment and training methods were presented.

The possibilities of rescue operations in mine shafts are presented on the basis of the description of characteristic rescue operations, richly illustrated with drawings and photographs.

The following events were presented:
