Abstract

Directions in improvement of efficiency and safety of the used systems for relocation of powered roof supports from the liquidated longwall was indicated basing on a review of the current systems. Suggestion for the machines and devices used for mechanization of a powered roof support relocation from a row and its transportation in cross-cut entry is presented. The innovations consist in combination of two functions in one machine used for roof support reinstallation and its rotation as well as its safe and fast relocation to the main transportation roadway.
