During opening of a new underground coal mine through inclines, some times it is very difficult to make first opening in the rocks even at some depth if the strata is not competent, especially in the case of poorly cemented medium to coarse grained sandstone. Support of the lip (mouth of the opening) in loose strata is very complex job. When the opening is made and prolonged at some distance, the problem is minimized. Resin bolting, which has been used during this study, is very important support system in bad ground conditions due to its fast setting nature and very good load bearing capacity. For permanent assessment of rock mass it is very important to study the amount of rock load coming around the openings. Hence an attempt has been made in this paper to throw some light on design of support system for driffts of a newly opened underground coal mines after detailed geotechnical studies of roof rocks, which is composed of poorly cemented strata.
