1100 and 1300m asl.
Location: latitude 39°28' to 39°34', longitude 106°36' to 106°40', Source: internal field report, 2002, unpublished
The coal layers of the Wuda coal field belong to the Upper Carboniferous and Lower Permian Taiyuan and Shanxi Formation. The
coal bearing strata was deposited in marine near coastal swamps.
24 coal seams with a thickness of 0.2m to 6m are exposed in a 10km long and 4km wide N-S striking syncline. The coal quality
is in the range of medium volatile bituminous coal. The surface of the Wuda coal field is strongly mined and mainly covered
by sandstone or loose sand.
An area of 280.000 m2 is effected by coal fires. Most Coal fires occur underground and can be related to small scale mining
