Abstract :The results of linear and multiple regression analyses to determine the relationship between spontaneous combustion parameters insert ignore into journalissuearticles values(derived from time-temperature curves obtained from laboratory tests); and coal parameters insert ignore into journalissuearticles values(obtained from proximate, ultimate and petrographic analyses); have been explained. The linear regression analyses have shown that ash insert ignore into journalissuearticles values(A);, volatile matter insert ignore into journalissuearticles values(VM);, carbon insert ignore into journalissuearticles values(C);, hydrogen insert ignore into journalissuearticles values(H);, exinite insert ignore into journalissuearticles values(E);, inertinite insert ignore into journalissuearticles values(I); and mineral matter insert ignore into journalissuearticles values(MM); are the major factors affecting spontaneous combustion. According to the multiple regression analyses, these major factors are volatile matter, carbon, hydrogen, nitrogen insert ignore into journalissuearticles values(N);, oxygen insert ignore into journalissuearticles values(O);, sulphur insert ignore into journalissuearticles values(S); and inertinite. As a result of this study, some empirical equations have been derived using statistical models.
