Coal Mine Methane And Coalbed Methane
Development In The Donetsk Region, Ukraine
The Bezymianniy Fault limits the mine area to the northwest, striking from south-west to
north-east. In the center of the area the strike of the fault is close to N-S. Within the limits of
the mine area, the trace of the Bezymianniy fault does not appear at the surface, but is
exhibited as a fault gouge in corewells 3983 and 3883, with no displacement of rocks
observed. Along the Chaikinskoy flexure fold, the strata dip 30 to 40 o to the southwest,
increasing up to 74°. The angle of dip of system decreases from 20° to 14° and within the
limits of the "Chaikino" mine, the fault flattens.
1.6.2.2 Coal Geology and Properties
The mineable coal of the Bazhanov mine is concentrated in coal-measures of the series C3 1
and C2 7 in which 48 coal layers and interlayers are contained. The series C3 1 contains 17
coal layers and interlayers, with only two of them workable over significant areas. The series
C2 7 contains 31 coal seams and inter layers, including 8 seams which reach working seam
thickness over most of the mine area.
The total mineable reserves of the Bazhanov mine are 62,628,000 tons with working seams
accounting for 15,824,000 tons of the total. The current mining capacity is approximately
1,600 tons/day from 10 coal seams, although currently only the m3 seam is mined via
longwall technique. The rank of the m3 coal is high-vol bituminous A with an average ash
content of 8.0%, a moisture content of 0.8% and the sulfur content around 3.5%.
