Experimental investigation on the characteristics of long-term submerged coal spontaneous combustion under varying heating rates

The low-temperature oxidation experiments were conducted on lignite immersed in water with short (50 days) and long (200 days) at three different heating rates (0.25℃/min,0.5℃/min, and 1℃/min), providing a theoretical foundation for the assessment of spontaneous combustion risk in goaf coal. Researc...
