Abstract

Sub-bituminous C coal stored in temporary stockpiles for long periods often causes sponta�neous combustion. Intensive spontaneous combustion causes negative impacts such as methane gas emissions that are exposed to the air. This research aims to analyze the effect of differences in organic sulfur content in the form of carbon disulfide on the formation of methane gas emissions in the spontaneous combustion of sub-bituminous C coal in the temporary stockpile. The method used in this research uses field surveys and the data are analyzed using normality and regression tests. The results show that the spontaneous combus�tion of sub-bituminous C coal that occurs in the temporary stockpile is strongly influenced by the organic sulfur content in the form of carbon disulfide and the water content of the coal. Regression analysis shows BB52HS coal with high organic sulfur content and low water content produces methane gas emissions of 1,450 - 24,000 ppm
