Coal reserves in the region are estimated as 800 million tonnes and the general properties
of the coal in the Soma Basin are summarized in Table 1.
Many faults intersect the coal formation in the region and these faults are mostly high
angle oblique-slip normal faults. Strikes of these faults NW-SE, NE-SW, and E-W directions
(İnci 2002).
3.2 Modelling of the LTCC operation
The excavation and transportation systems of an LTCC operation located in western Turkey
were modelled in Arena
® Software. Although operations were performed in two production panels, only one of them was modelled. Cutting parameters in the modelled panel are
presented in Table 2 and the equipment used in the coal excavation operations are given in
Table 3.
Transportation of the coal from the face is achieved by an AFC, RC, BSL and three different belt conveyors (BC-1, BC-2, and BC-3). Specifications of the conveyors are presented
in Table 4.
