Geotechnical Properties of Open Cast Mine
Open cast mining has grown at phenomenal rate in India because of increasing demand for energy. Open cast mining has raised to 250 million tonnes which represents 70% of overall coal production. This type of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. These mines were used when deposits of commercially useful ore or rocks are found near the surface, i.e., where the overburden soil is relatively thin or the material of interest is structurally unsuitable for tunneling. In this paper, geotechnical properties of overburden soil are determined. Soil samples are obtained from Gouthami open cast mines at depths of 50, 100, 150, and 200 m to assess the depth-dependent behavior of soil. Samples are tested for particle size analysis and compaction properties. Compaction curves indicate that optimum moisture content varied from 10.8 to 13.3% along with depth. The dry density of soil is varying from 1.96 to 2.03 g/cc.
