Summary / Kata Kunci : The subjects of this research were T-100 and T-200 coal seam in the Tutupan area, Tabalong Regency, South Kalimantan Province. The aim of the research was intended to explain about the control of stratigraphy against the increasing quality of the Warukin Formation coal. The result was based on the depth versus physical properties of the T-200 coal seam as follow: the inherent moisture and total moisture the deeper of the T-200 coal seam were lower then those the upper of the T-200 coal seam. The volatile matter, fixed carbon, calorific value, ash and total sulfur the deeper of the T-200 coal seam were higher than those the upper of the T-200 coal seam. Therefore, it can be concluded that the higher the overburden pressure the lower the inherent moisture, total moisture, ash and total sulfur as were. In opposite, the higher the overburden pressures the higher the volatile matter, fixed carbon, and calorific value. The thickness of overburden with gradient geothermal of 1.95° F/100 ft brings about pressure 369 atm and temperature of 99°F. It did not reach the precondition of the coalification. Although temperature and pressure did not reach the level which was necessary for the forming of coal, there were other factors to decide the process of coalification. That was time and other geological factor. Those geological factors were among other volcanic activity, ground water flow, thermal conductivity, dewatering orogenic, fault influence and transgression-regretion. There was not enough reason of the influence of radioactivity decay to the thermal maturation of coal.
Key word: stratigraphy position, coal quality
