Influence of physical and chemical properties on the thermal behaviour of coal: a comparative study and regression-based assessment of two Indian underground mines

Key Points

• Thermal behaviour varies significantly across different coal samples, indicating differing physical properties.
• The analysis revealed a correlation coefficient of 0.87 in the regression-based assessment of coal samples.
• Comparative study across two Indian underground mines assessed coal's physical and chemical properties.
• These findings may improve mining efficiency, emphasizing the need for tailored extraction strategies.
