New Reconstruction Technologies Of Safety Pillar In Mines / Nowoczesne Technologie Odbudowy Filara Bezpieczeństwa w Kopalniach

Safety pillars are made around mines as a protection measure. This is especially important in salt mines where the surrounding waters are most hazardous. Without maintaining safe conditions the mine may be water-flooded as it was the case in one of the Polish mine “Wapno“. An original technology linking pipeline injection and hole injection methods has been used for the reconstruction of a safety pillar in the Salt Mine “Wieliczka“. This solution turned out to be successful when on 13 April 1992 the mine was saved from flooding after a disastrous water flux to the transverse working Mina. The presented technology can be efficiently used in various mines at the stage of designing, though their exploitation to the closing stage.
