Abstract: This paper refers to the role of strata monitoring instruments in risk assessment of roof falls in an underground coal mine. Detailed investigation in to the factors responsible for roof fall was carried out in an underground coal mine situated in Central India. The investigation was supplemented by In-situ stress assessment by drilling yield measurements and convergence recording by strata monitoring instruments. It was observed that strata monitoring instruments gives early indications about initiation of strata movement and potential roof fall. The proper analysis and interpretation of the readings from strata monitoring instruments is very much helpful in updating the risk assessment and preventing the roof fall by risk management
