Abstract

The average depth of the underground coal workings has increased considerably due to the exhaustion of coal deposits near surface. Nevertheless, the coal extraction at depth is overwhelmed with geomining issues due to high in-situ stresses, dynamic behaviour of rockmas, large dilation in mine openings, etc. Therefore, to extract coal from deep mine safely, this paper assesses the geomechanical issues and the mining challenges of deep mining and emerging methods to manage these issues eectively for Indian mining conditions. The geo-mechanical issues have been assessed based on the basic rock mechanics of deep mines. The mining challenges are analyzed focusing on stable working face, roadways, transportation, etc. The comprehensive survey and critical studies of the emerging underground mining methods are done to nd out the prospective methods of underground mining which can negotiate the complexities of deep-seated coal deposits in India. The selection of mining methods suitable to the characteristics of coal deposits has been discussed and suggested for mining at greater depth. The works presented in this paper are highly pertinent to Indian mining industry and would provide an insight to select greener, economical and safe mining method to extract deep-seated coal deposits
