Incorporation of new solutions of mining machines and equipment is directly associated with securing a proper safety level to the machines’ operators. Protection of operators against roof falls is one of the methods for increasing operators work safety. According to the standards and legal acts, the self-propelled machines, which operate underground, have to be equipped with protective structures. Legal acts and standards determining the requirements, which are put to the protective structures for operators, which work on machines in underground mine roadways as well as KOMAG’s experience in designing of operator’s protective structures are presented in the paper.
