Description In underground coal mines, a number of fatal accidents have been occurred due to roof fall. The roof fall mainly occurs in newly exposed working sections of coal mines during development and final extraction of coal. The main factor which contributes to the roof failure in coal mines is the re distribution of stresses and geotechnical discontinuity. If a proper support system is not provided in time the layers get detached and fall down causing major causalities in the mines. Rock mass rating (RMR) plays important role in design and selection of adequate support system. In Indian coal mines, Central Mining Research Institute- Indian School of Mines - Rock Mass Rating (herein after referred to as (CMRI-ISM RMR) is mostly used for formulating design guidelines for supports. In this paper study for stability of II seam working was assessed. Later on study was extended to determine rock load for II seam applying empirical and numerical approaches and finally design of support has been formulated.
