HIGHLIGHTS
- Parameters of the computational model of the suspended monorail was identified.
- The emergency braking method has a direct impact on the overload values affecting on the crew.
- Increasing the speed of the suspended monorail requires the identification of emergency braking parameters.
- The value of the safe crew transport speed has an impact on the extraction process efficiency

ABSTRACT
Due to the longer distance of moving the crew to the workplace in hard coal mines, the
possibility of increasing the maximum permissible speed of suspended monorails was considered. To ensure an adequate level of safety, decelerations affecting the crew in the case
of emergency braking in various travelling conditions were analysed. The computational
model was verified based on the results of the bench tests on a dedicated test track. The article presents a comparison of results of numerical calculations with measurements at the test
stand, and results of numerical simulations in relation to the criterial states that could not be
checked at the test stand as well as the analysis of overloads that affect the crew during the
emergency braking. These overloads have a significant impact on safety of the operator and
passengers, and their determination and analysis may be the basis for assessing the degree
of safety as well as for the development of guidelines for designing the additional equipment
for the operator's cabs and passenger cars, i.e. components increasing their safety
