ABSTRACT

Coal mining is connected with many burdens, which affect mostly the safety of mining.
One of the most serious problems is exhalation of methane to the mine air.
This Paper describes methods used for degassing in Czech Republic’s underground coal
mines. Authors deal with new options and new trends in maintaining security by the
means of degassing drill holes. There are two main methods Czech Republic used to
prevent accumulation of the Methane gas in gaseous mines. The first method is
sufficiently effective ventilation. In this case the greater the amount of fresh wind is, the
thinner the concentration of methane is. The second method is extraction of methane
from the rock face before the beginning of mining by the means of degassing.

Keywords: Mine degasification, degasification systems, degasification boreholes, methane
