Understanding the characteristics of coal spontaneous combustion (CSC) in goaf under different porosities is crucial for comprehending mechanism CSC and its prevention control. In this paper, a multi-field coupled model goaf, considering porosity variation, developed to investigate effect on goaf. The results indicate that, as depth increases, both permeability decrease. When highest 25%, average airflow velocity between 0.00134 0.00139 m/s. contrast, with 40% approximately six times greater...
Coal spontaneous combustion (CSC) often occurs in environments that are poorly ventilated or under lean-oxygen coal mines seam outcrops. The understanding of the thermodynamic properties CSC conditions is important to avoid safety and environmental problems. In this paper, mass variation critical temperature (the minimum required for reaction each stage) six coals during were investigated using thermogravimetric methods. Furthermore, thermodynamics parameters kinetic compensation processes...
