Geologically there is a dome structure (the Pinang dome) in the centre of the property. Overburden is mainly sandstone, siltstone and mudstone. Early mining focused on the edges of the dome and virtually all coal seams dip away from this region. A total of 13 seams range in thickness from 1 to 15 m; typically in the range of 2.4 to 6.5 m.

This has been mainly attributed to the weathering process that intensively occurs in the tropical regions. It is therefore appropriate to carry out a research of shear strength characteristics on rock samples of the predominant coal bearing strata such as sandstone which are obtained from Tutupan coal mines in South Kalimantan, Indonesia.
