Abstract:

Currently, the insert plates for underground mines are all using heavyweight concrete, so the plates are quite heavy, making difficult to transport plates and construction underground mine. Lightweight Expanded PolyStyrene concrete (EPS-C) has been researched and applied as a covering structure, heat and sound insulation material in civil engineering. In this article, results of research on fabrication of insert plates for underground mine from EPS-C are presented. The result showed that the insert plate fabricated from EPS-C has the same failure mechanism as conventional concrete, load bearing capacity of plate reaches 72,8kN/m2. According to the obtained results, it is possible to use EPS-C for mass production insert plates for underground coal mines of TKV
