Abstract

Spontaneous-combustion coal is a natural phenomenon that often appears at an open pit coal mining activity. This phenomenon leads to the methane (CH4) emission. It has been known that the CH4 emissions contribute up to about 10% to the global warming, in which the emission from open pit coal mining activities contribute up to 34%. This study is designed to measure the CH4 emission in a front mining at Air Laya Field, PT. Bukit Asam (Persero), Tbk, South Sumatra, Indonesia. There were 43 samples used in this study, which were observed randomly from a spot of spontaneous-combustion coal at a front mining. The resuts show that the mean CH4 emission in the study area is about 1.14 ppm, while the cummulative CH4 emission is about 49.05 ppm. The mean CH4 emission observed in this study is smaller compared to that observed at an open pit coal mining in Australia, which is about 2.80 ppm.
