Abstract
In the Polish brown coal mine Belchatow deformation and stress behaviour are investigated to learn in early stage any reaction of this surface coal mine pit. These values are critical in regard of landslide risks as also important for the most economic excavation geometry. As already reported in GTMM 2002 conference in Karlsruhe, a standard stress monitoring station has been installed and first results have been reported. An important task is to get confident values not in high-precision but in long-term stability. In cooperation with my Polish colleagues and the BAM (German Federal Institute for Material Testing), Berlin, a new EFPI Stress Monitoring Station has been installed in this coal mine and first experiences and results have been reported.
