The productivity and economic success of a German hard coal mine is
attributed to the high productivity of a small number of operation points;
however high rates of production are associated with increased gas
emission at the working sites. Therefore modem high technology is
required in order to reach the planned production rate, since high methane
concentrations often cause unplanned breakdowns in operation. The optimised simulation of gas emission is a fundamental planning
tool for mine design as well as for determining the potential of a coal
deposit and has increased in significance over the last years. Methane-INFO enables the three-dimensional, graphical simulation of
a working site taking account of different aspects such as the mine design,
ventilation, production rate, geology, seam quality, gas exhaustion, etc.
The following paper gives a short overview over the benefits of the
discussed system.
