The geo-technical problems faced in thick seam mining in India are multi-fold, notables are conventional supports having serious limitations, inadequate rib design resulting into ineffectiveness and many time unpredictability at the goaf edges and risky caving in- bye. Most of the mining endeavors in thick seams are confined to semi-mechanized propositions. Mining with stowing becomes techno-economically non-viable due to fast pace of retreat now being planned and the rate of stowing not matching with it. In this paper, a review of different mining methods in bord and pillar (B&P) pattern with caving as goaf treatment have been presented. Longwalling and its variants like LTCC (Longwall top coal caving), multi-level and multi-section caving, etc. are yet to be established in an R&D demonstrative trial panel and hence not included in this paper. The case-study observations in B&P pattern have been analyzed so as to provide the mine operators to take cognizance of challenges and opportunities in this regard. The latest updates about various research inputs by CSIR-CIMFR have also been provided within the realms of thick seam mining methods.
