Assessment of an Open Cast Coal Mine Slope Stability at Mohanpur Block, Raniganj Coalfield, West Bengal, India
A large open cast coal mine always needs a stable side slope to prevent collapse due to excessive overburden pressure. The present study was undertaken to assess the stability of slope of an open cast coal mine located in Mohanpur block in the Raniganj coalfield area in West Bengal, India. The pseudo-static approach of stability analysis was performed using Plaxis 3D software package under strength reduction technique. A Mohr–Coulomb constitutive model was considered for the simulation of geological materials under drained and undrained conditions. The average overall depth of the mine slope was considered as 144 m. The slope was designed following the coal mine regulations of mechanized open cast mining (CMR 2017) [1], Ministry of Labor and Employment, Govt. of India. The maximum vertical deformation and safety factor were examined to ascertain the optimized slope angle of the Mohanpur open cast pit. Three trial slopes were considered using three different slope angles. The slope angle of 40° was selected as the design slope as the safety factor as well as vertical deformation was found to satisfy the permissible limits under seismic accelearations considered in the present study.
