Applicability of data from trenches for reserve calculation is low.
The thickness value observed in trenches can not be used, as the intensive weathering impacts the different volume changes of both the coal and the argillite layers.
The most explored part is the tectonic block II For the purpose of geological mapping the promising coal seams have been numbered in the range of 1 to 32 as per the documentation of the trench TR 1.
West of TR 1 the coal seams are quite well traceable between the trench and F3-1 fault The development of coal seams to the East is very similar as far as the fault F4.
Correlation of the seams for reserve calculation was performed based on the results of surface tracing of seams by pits and trenches, results of tunnelling and results of cyclic analyses of the borehole logs.
