Abstract:  In Indian coalmines, CMRI- RMR and NGI-Q Systems are mostly used for formulating design of support in rock engineering. Geotechnical investigation of the roof rocks plays an important role in the selection of different parameters used in rock mass classifications. In India, Bord and Pillar Method of mining is very much in practice in underground coalmines. Roof support, which is an important aspect of ground control, involves maintaining roof competency to ensure a safe and efficient mining environment. This paper deals with a case study where CMRI- RMR and NGI Q- Systems are used for estimation of rock load for design of support in a coalmine in India in semi-mechanized depillaring workings with desired success.
