Investigation for Safety of Final Quarry Bench During Mine Closure Stage – a Case Study

Abstract The closure of opencast coal mining operation in Balanda mine will be a source of danger for inhabitants or any other infrastructure near the surface of ultimate quarry bench from safety point of view. In view of the above, MCL (Mahanadi Coalfield Limited) and the management of the Balanda opencast mine conducted a variety of design research and academic institutions to conduct a slope stability analysis of Balanda ocp (opencast project). It is also important here to note that the Birla Institute of Technology, Mesra, Ranchi, has prepared a study report on the above. This paper deals with design of ultimate quarry bench and discusses various geo-technical parameters for carrying out stability analysis.
