Abstract

Belgaon block is located in the northern most ends of explored coal block of the eastern limb of Wardha Valley Coalfields (WVC). WVC is well known for its complexity like complex geological structures, strata control problems while dealing with thick coal seam, fire and water problem etc. The Belgon mine of SUNFLAG is however separated from Majra block in the south by a down throw fault. Designing of road ways and junction support in newly opened underground coal mine was a challenge due to its complex geology. To arrive at suitable support system, various experiments using cement as well as resin bolting were carried out. The pulls out tests were carried out on rock bolts grouted with cement as well as resin. The proposed paper deals with significance and importance of resin grout over cement and other issues related to strata control etc.
