In the Central Mining Institute tests have been carried out on the use of epoxy resins for glueing carbonaceous rocks occurring in the region of Upper Silesian Coal Basin. During laboratory tests viscosity variation of epoxy resins during gelation was analysed, their strength and also possibility of adding fillers in order to limit resin consumption. The mine tests have shown that resins with low viscosity /about 1 N • sec/m2 / are suitable for strengthening the cracked and brittle rocks under dry and wet conditions. However, the flow of water through joints of glued rocks makes strengthening difficult and causes high losses of epoxy resin.
