A detailed geological mapping, recording the data on Joints and faults to assess the stability of slopes of both Sedimentary and Metamorphic benches in one of the opencast Coal mines ie RG OC-II of the Singareni Collieries Company Ltd (SCCL) located in Godavari Khani is planned as a part of deepening the workings to a depth of 400 m and to raise the height of OB benches from the present 90 m to 120 m. In this connection, a detailed mapping is planned and generated all desired data. Mine authorities reported that 60cm of sliding is observed in Highwall towards SE-NW and is along the major boundary fault (F1). The paper deals with the Structural Mapping to assess the stability of Over Burden benches in the Opencast Coal mine. An attempt is made to compare the data on joints generated by different Institutions/agencies in different locations within the same block.
