Stope Design for Conservation of Mineral and Safety in Underground Manganese Mine – A Case Study of Munsar Mine of MOIL Limited

Abstract

MOIL Limited is the major manganese producer of the country. Manganese is mined chiefly by underground
mining. Cut and Fill method of stopping is adopted in underground mines along with sill and barrier pillars to
protect the levels. Valuable manganese ore is locked in sill pillars and to stope design analysis was conducted to
improve reserves. Models were prepared with modified stopping methods for stability analysis. This paper
presents the outcome of the study.
