Nowadays, in the coal mining industry, achieve to goals such as high production rates and efficiency with increasing safety and reducing production costs needs to using mechanized mining methods and advanced equipment. As case studies, Takht coal mine and Tazareh coal mine in north-eastern of Iran and Tabas coal mine in mid-Eastern Iran were selected. In total, 17 coal seams with the potential for mechanization from three mentioned mines were studied. In this present study in order to evaluating these coal mines potential of mechanization, important and influential factors such as seam inclination, seam thickness, roof strength, seam uniformity condition, seam extension, bearing capacity and water at the working face were investigated. In this study, it was tried to select the best seams between studied seams with potential for mechanization based on the mentioned factors, by using Preference Ranking Organization Method for Enrich Evaluation method. Finally, Tabas and K11 seam from Takht mine were selected as the top options for mechanization. [ABSTRACT FROM AUTHOR] |
