| Description |
In India, CMRI-RMR (Central Mining Research Institute- Rock Mass Rating) is an empirical approach, used mostly for formulating design of support system for roadways in underground coalmines. RMR plays important role in selection and design of roof support [1]. For stability assessment of rock mass it is very important to know the amount of rock load coming around the openings which is estimated using RMR [4, 7, 11, & 12]. The result revealed that sandstone as immediate roof is more stable compared to shale and coal. Attempt has been made to delineate the variation of RMR for different roof rocks in mines of Jharia coalfield. This would also help as useful guidelines in design of support system for roadways in other underground coalmines of Lower Gondwana Formations having more or less similar geo-mining conditions.
