The Ministry of Power and the Government of India are installing new units of coal-based thermal power plants in the various thermal power stations across India. Bulk material such as coal is being transported to the power plants mainly by railway wagons. The wagons are unloaded on conveyor belts by mechanisms such as a wagon tippler complex (WTC) and a track hopper. For one of the projects in Bihar, the scope of work is to construct a wagon tippler for unloading coal from railway wagons. As a part of the Coal Handling Plant (CHP) facility, the CHP-WTC facility stretches to an approximate length of 235 and 20.5 m deep from natural ground level. A 20.5 m deep open-cut excavation is envisaged for the Wagon Tippler Complex of the Coal Handling Plant. Subsoil is characterized as very stiff silty clay, followed by a clayey silt layer and a dense sand layer at the bottom. The water table is observed at 3 m from the existing ground level. To increase excavation efficiency and to reduce the overall time and cost, a dewatering scheme is designed with a multi-level deep well point system. Pseudo-static slope stability analysis, considering rainfall simulation and sensitivity analysis, are carried out to optimize the actual requirement of the excavation slope. For places where width restrictions are encountered, a soil nail wall is implemented to practice safe excavation under critical scenarios. Seepage analysis with a well point system shows a gradual reduction of water without any slope failure hazard. Open cut excavation with different soil profiles up to 20.5 m depth found achievable by careful stage construction in static and seismic conditions.
