Determination of the limit angle at the Manisa-Soma-Eynez coal field, a major coal production area in Turkey, is difficult because of the presence of a landslide caused by the waste from a neighboring open-pit site being dumped over the underground mine at the Soma-Eynez basin. In fact, it is not possible to determine the effect of extraction on the surface from field studies. Thus, in order to determine the limit angle, in-situ subsidence measurements, geophysical measurements, rock-based tests in the laboratory and the data obtained from a physical model have supported numerical modeling studies. The software, LAMODEL, used for the numerical modeling was developed by National Institute for Occupational Safety and Health (NIOSH), and is based on the Boundary Element Method. The results obtained from modeling have been found to be compatible with other studies and as a result the limit angle has been determined. (C) 2004 Elsevier Ltd. All rights reserved.
