INVESTIGATION OF SOMA REGION COALS WITH RESPECT TO SPONTANEOUS COMBUSTION SUSCEPTIBILITY

Abstract

One of the factors that make coal mining difficult is the spontaneous combustion of coal. Spontaneous combustion including various parameters is not only met in underground mining, but also in surface mining, stockyards and long-distance transport of coal by land and sea. This event, which threatened the occupational safety in mines, has effects of causing loss of lives and defecting human health. In mining enterprises, it causes production losses along with economic losses. It is a serious matter that requires good planning and supervision in order not to cause irreversible damages. Spontaneous combustion of coals develops depending on internal, environmental factors and production methods. In order to eliminate the problems caused by spontaneous combustion, the spontaneous combustion conditions of coals must be determined and classified beforehand. In this study, spontaneous combustion tendencies of Soma Region coals were generally determined with samples taken from Işıklar Colliery, İmbat Mining and Eynez Colliery of Demir Export. Using the crossing point method, a total of 30 experiments were carried out with 10 samples taken from each colliery to find out the risk of spontaneous combustion of the Soma Region coals. Based on the values obtained, it has been determined that the coals of the Soma Region have a "high" tendency to spontaneous combustion.
