Design of an Equivalent-Material Modeling Facility for Underground Coal Mines.
Proc 4th Conf on Ground Control for Midwestern U S Coal Mines So Illinois Univ PP 239-254 :239-254
The physical modeling facility being constructed at Southern Illinois University, Carbondale, Illinois, 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. 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.
