... and the moisture content of the floor. Data is also presented on the load bearing capacity of the floor as determined by in-situ plate tests. The 132 different plate tests from 17 coal mines form the largest database of its kind for the Illinois Basin mines, which helped develop new strength relationships for use...

... technique. The experimental results show that the moisture content of shale is correlated with water activity using a multilayer adsorption theory. It is found that the adsorption isotherms of various shale formations can be scaled using their respective cation exchange capacity, into a single adsorption...
