Vertical Distribution of Total Sulfur in Coal Seams in Tamalea Village, Bonehau Regency, West Sulawesi Province

Sulfur content plays an important role in determining quality and utilization of coal. This study analyzes the total sulfur content in the coal seam, overbunden, and underburden. The aim of the study is to analyses the vertical distribution of total sulfur content in the eight samples (four coal, two overburden and two underburden samples). Coal sampling in this study is done by channel sampling with ply by ply method. The analysis of total sulfur at A and B stations show that the overburden (roof) has total sulfur of 0.20% and 0.23%, the underburden (floor) has total sulfur of 3.85% and 5.80%. The coal sample at the top ply (ply 1) has total sulfur of 0.86% and 1.30%, while the coal at the32 bottom ply (ply 2) has total sulfur of 2.27% and 4.45%. The data shows that the total sulfur content in the bottom ply (ply 2) of coal and underburden (floor) is higher than in the top ply (ply 1) of coal as well as overburden (roof). It can be concluded that the concentration of total sulfur tend to be low (decrease) from the floor (underburden) to the roof (overburden).
