ABSTRACT
Impact of the method of suspension and route stabilization of suspended monorail on forces
loading the roadway roof support system is presented. This is important in the context of
possible increasing the speed of monorails during personnel movement. Nature of load and
displacement of the route, as well as deceleration of the transport set, with a dynamic excitation - an emergency braking of the transport set, are presented. The results are presented for
seven configurations of slings and lashings stabilizing the route. The Head Injury Criterion
(HIC), recorded using the Articulated Total Body (HYBRID III) model, during the impact of
operator's cabin against an obstacle, is presented in the further part of the article. Analyzes
are aimed at developing the guidelines to ensure safety of mining personnel (without exceeding the accepted overloads) and mining infrastructure (without exceeding the maximum
accepted load of the roadway support) during operation of the suspended monorail at higher
speed. Analyzes are the result of the authors numerical simulations.
