The physical modeling facility being constructed at Southern Illinois University, Carbondale, IL, under contract with the U.S. Bureau of Mines will be able to simulate the vertical and horizontal stresses occurring at various depths in underground mines. Different coal seam thicknesses and inclinations will also be simulated. Embedded pressure cells and linear variable differential transducers will monitor loads and deformation of the model. The instruments are connected to an automated data acquisition system that will collect and analyze the data. A digital imaging system will record the results of tests. The physical model will be 10 ft long, 6 ft high, and 0.75 ft deep. Equivalent materials that can simulate coal measure rock and types of ground control problems that can be studied using the test facility were identified.
