Study on the Relationship between the Depth of Coal Seam and the Quantity of CH₄ Produced

Abstract:

Based on the geological and the experimental data of the 13^#coal seam of Sun-Cun Coal Mine, the relationship curve between the depth of coal seam and the amount of CH₄ produced has been fit out. According this and the laboratory experiments, the relational expression between the quantity of CH₄ and the period of spontaneous combustion has been obtained. The research results show that the relationship curve between the period of spontaneous combustion in coal sample and the quantity of CH₄ fit exponential expression. Especially when the quantity of CH₄ produced exceeds 5 mol / (Kg min), the period of spontaneous combustion in this experiment is almost unchanged. This law should be paid more attention to.
