ABSTRACT

The paper deals with the concepts of monitoring and extraction of silica sandstone with
dolomitic cement in the Bilina Mine in relation to innovative alternatives to its use in
the coarse and fine production of stonework.
In the first section, there is a description and characterization of the Bilina mine, as a
part of Severočeské doly Chomutov (SD Company), currently in its mining of brown
coal, being the biggest supplier of this raw material for the Czech energy industry, with
its share of the deliveries for the Czech market at more than 50%. The next section
describes the geological and geographical characteristics of the brown coal deposit, then
the listed available methods of selective extraction of solid-rock layers in overburden
and technical and technological parameters of the sandstone occurring in a given
location (ie in the northern part of the mine-the 5th and 6th working levels).
The following section presents a discussion on mining technology, not only about
continuous technology, but also by cyclic technologies which use global positioning
systems, which are also used to monitor solid-rock formations occurring in the mining
area.
The conclusion of the paper is devoted to the existing knowledge about disposal of
dolomite cemented silica sandstone that the Bilina Mine gained during the decades
when the raw material was liquidated.
On the basis of this knowledge, there are listed, all the options available for use of silica
sandstone as regards Bilina Mine’s own needs, including innovative alternatives to its
use in the rough and fine production of stonework, which is presently only in its infancy
at the Bilina mine.
