    An innovative crossing powered support of the HENNLICH-20/43-CH type
    (Wydawnictwa AGH, 2022) Wojtas, Marek Daniel; Kazubiński, Damian; Pilarz, Klaudiusz
    The underground mining of minerals with a longwall system requires the construction of two parallel galleries (bottom road, top road). As the longwall progresses, they are eliminated (mining from the boundaries). Reconstruction of this area, i.e., the wall-road crossing, is usually carried out manually. Other methods can be used to reduce the physical effort of handling the wall. One way is to use supports dedicated to these locations and an example of such a solution is the HENNLICH-20/43-CH support. The article discusses the advantages of using mechanized power support as an alternative to development with individual props. The technical parameters of the selected type of mechanized power support are presented.
