Underground mines are generally supported with wood and steel-based support systems. The wood-based supports such as wooden props and cribs/cogs carries less load due to its weak in nature and takes so many years to grow to certain size. The steel-based supports such as steel props, roof bolts, steel arches, and steel cogs are made of Iron ore, which is a non-renewable resource and being depleted every year. Hence, it is imperative to develop the novel support system (PVC-Concrete) which carries higher load, serves more life and gives indication for improving the safety of underground workings. For this, few samples of PVC-Concrete support props are prepared in the laboratory and tested under compression to determine its carrying capacity. From the laboratory tests, it is found that the compressive strength of 25 MPa was obtained for sample L/D ratio of 7.3 and these samples failed at compressive displacement of 13–15 mm. Also, several 3D numerical models of support prop are developed to analyse its behavior by applying various loading conditions. Each numerical model consists of PVC concrete prop in between steel loading platens on its top and bottom. The results in terms of stress, strain and deformation of the support props are extracted and analysed. The results of the 3D numerical modelling reveal that the PVC-Concrete props can take huge load due to confinement provided by PVC and enhances the safety of the mine workings.
