Abstract

The paper deals with pillar and roadway stability assessment of development working of Ukwa underground metal mine of Manganese Ore India Ltd (MOIL). The assessment was conducted with rock mechanics instrumentation. Nine strain bars and six tape extensometers were installed to measure the strain and convergence in the roadways and strain in the pillars having size smaller than designed. The monitoring was continued for more than eight month. The factor of safety (FS) was calculated for some randomly selected pillars and suggestions were made for their long-term stability if FS is less than 1.5. This paper describes in detail the above instrumentation scheme, analysis of data and FS evaluation.
