Abstract

The article presents an optimization of Ø0.21/0.16 hydraulic leg system operating in a powered roof support Glinik 13/25 Pp type, working at longwall 6, seam 501, KWK Bobrek – Centrum in hazard conditions of mining tremors. The process included numerical modelling and computer software, ANSYS CFX. The optimization allows to achieve an adequate capacity and performance of the hydraulic system which increases workplace safety in the mines. The article provides basic requirements that must be provided in order to conduct an analysis in ANSYS CFX. The software was used to carry out 10 simulations, which allowed to determine an optimal flow for the subject leg.
