W artykule przedstawiono wyniki badań linek ratowniczych trzech typów, używanych przez zakłady górnicze oraz OSRG Bytom – Zabrze zarówno podczas prowadzenia akcji, jak i ćwiczeń ratowniczych. Celem analiz było określenie czasu zapinania i odpinania oraz sposobu poruszania się zastępów ratowniczych w aparatach regeneracyjnych W-70 w zadymionych wyrobiskach komory ćwiczeń OSRG Bytom – Zabrze oraz w warunkach bez zadymienia.

In mines, rescue operations are often performed in excavations filled with smoke and with the use of breathing apparatus. Such excavations may only be entered when rescue lines are used, while any activities connected with rescue line fastening should be performed quickly and effectively to avoid the separation of the rescue team. In 2018, tests involving rescue lines were performed at the Bytom – Zabrze District Mine Rescue Station. The objective of the tests was to determine the time required to fasten and detach such lines and to determine how rescue teams move in the W-70 breathing apparatus both in test chamber excavations filled with smoke and in such excavations without smoke. Three rescue teams from three mines participated in the tests. Three types of rescue lines were used: a reflective one with a length of 10 m, of GL087 Protekt type with a length of 8.5 m, and a line with fastening hooks 5.5 m long. During the tests, the rescuers performed exercises in three stages, in different and specific places of the test chamber. All stages involved the time required to perform exercises by individual rescue teams. The tests revealed that each line was successful in its purpose. At any stage rescue teams did not separate and the line did not detach accidentally. Nevertheless, all exercise stages were completed the fastest with a 5.5 m rescue line with fastening hooks.
