【 摘 要 】

Inversion modelling 3D gravity has been applied to identify volume of the coal. Inversion modelling 3D gravity used inversion singular value decomposition (SVD) and inversion Occam on Bougeur Anomaly. Volume is measured by software Voxler. The Result from inversion of model 3D can show coal layer with density 1.32 g/cm3 on Low Land Ketungau at West Side of the map. The volume of coal at Sanggau Map is predicted to be 37.425.694,24 m3. The Research can be used as preliminary model for geophysics.
