Abstract

  In order to stabilize degraded rock mass, procedures of injecting polymer synthetic composites into wells or fissures around constructed underground chambers and facilities are being increasingly used today. initially epoxy resins were used at underground coal exploitation, and then they were replaced by polyurethane resins (PUR) without foam, and only later by polyurethane resins (PUR) with foam effect. After that, quick-setting two- component synthetic resins characterized by much shorter time of binding were used. Few years ago, the usage of elastic silicat isocyanate resins (ESR) with higher elasticity began, and they found their use in rehabilitation of mine chambers requiring either mean or longer usage term.
