Abstract
The Singareni Collieries Company Limited (SCCL) carries out exploration and exploitation of coal deposits of Early Permian Barakar Formation in the 350km long NNW-SSE trending Pranhita Godavari Valley located in the state of Telangana, India. Empirical studies undertaken by SCCL established an exponential relationship between Vp obtained from sonic logs and UCS determined on core samples of sandstones of from all parts of Godavari Valley. Polynomial and exponential relationships are also established between Vp and Tensile Strength (TS) and Vp and Young's Modulus (E) respectively. The empirical relationships can give a major opportunity to understand the implications of regional and local geological and geotechnical conditions on planning and managing various types of mines.
