Nová dobývací metoda chodba-pilíř v uhelných dolech

Abstract

The region of the Czech Republic has a long history of bituminous coal mining extending nearly 200 years. Longwall mining has been the traditional method of mining, but due to its subsidence impacts cannot be fully used under some densely populated areas. Thus an experimental project has been undertaken at CSM Mine operated by OKD, a. s. in the Czech Republic. The Room & Pillar method was chosen mainly to minimize subsidence impacts and this dissertation will analyze the many challenges involved in implementing room and pillar mining at great depths in a region that has never tried this method before; preparation and experience from the trial operation as well; conditions of employment in deep mines.
