Abstract: This paper presents results of a detailed study on the stress distribution in longwall barriers during extraction of coal in an underground mine. Analysis was carried out on the stress obtained at different locations in the barrier using finite element modelling and field monitoring. Results indicated that the zone of barrier lying in goaf experienced higher stress when compared with barrier lying in the solid zone. Stress in the region of barrier lying between 10 m ahead of face and 40 m behind the face (barrier section lying in goaf) was found to be the most critical in the design of barrier. 2010 Inderscience Enterprises Ltd.
