  • An analysis of potential increase in speed of suspended monorail is presented.
  • An analysis of the impact of route stabilization on dynamic loads of the support is included.
  • An analysis of the impact of route stabilization on forces affecting the operator is included.
  • The impact of dynamic interactions of the monorail on the biomechanical parameter is assessed.
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.
