Grouting of old flooded workings at M. Mayerova Mine in Czechoslovakia

Abstract

The paper is concerned with the design of a surface mining operation above a waterlogged underground mine workings in order to prevent ingress of water and control mine water pollution. The site of investigation was situated at M. Mayerova Mine, near the city of Karlovy Vary, Western Czechoslovakia which was operational at the end of 19th century. These mine workings were abandoned and subsequently, presented the a problem of eliminating flooded mine workings encountered in Jozef Seam at a depth of 176 m and two 4 m. diameter, No. 2 and No. 5, vertical mine shafts. The proposed mining operations were planned to extract overlying Antonin Seam at a depth of 88 m. below the surface by open casting technique and to prevent ingress of water into the planned workings.
