PT.XYZ is a coal mining company in Tabang District, Kutai Kartanegara Regency, East Kalimantan Province. Overburden stripping activities require a landfill, hereinafter referred to as disposal. Geometry planning and disposal location must be well studied because it can affect the required operating costs and the stability of the disposal itself. Disposal sampling location are carried out at two points, namely Dozer Push 1 (DP1) and Dozer Push 2 (DP2). Based on the results of laboratory tests, it can be seen that the material disposal from DP1 has a natural weight value of 17.21 kN / m3, cohesion of 31.54 kPa and friction angle in 23.27⁰. While the material disposal from DP2 has a natural content weight value of 17.54 kN / m3, cohesion of 29.44 kPa and friction angle of 22.40⁰. Analysis of the disposal slope stability produces a recommendation single slope geometry that is safe for disposal DP1 and DP2 is at 6 meter height with angle 63⁰. In that geometry the single slope ...
