This paper presents geo-mining conditions along with the problems of coal bumps encountered at Chinakuri Mine of ECL (Raniganj coalfield) and Lazy Mine of OKC. Further, the developed and practiced measures at Lazy Mine of OKC to control the coal bump are detailed and analysed to assess their suitability for underground extraction of Dishergarh coal seam of Chinakuri Mine, ECL. It is observed that the conventional techniques, being practiced to release the stress concentrations and to create a network of fissures in the solid accompanying rocks in Indian coalfield, need a complete change. On the basis of this analysis, a suitable method of mining with overlying strata management approach is advised to suit the onditions of the Chinakuri Mine of ECL.
