Strength reduction on saturation of coal and coal measures rocks with implications for coal pillar strength

Coal and associated coal measures rocks, including shales, mudstones and sandstones, may lose significant strength on water saturation due to the absorption of water, stress corrosion or mineralogical changes to the clays within the rock matrix. As most coal seams are natural aquifers, water ingress...
