A simple method for determination of bearing strength of weak floor strata in underground mines has been evaluated based on physical modeling approach, with regards to plate loading test conducted on simulated floor strata. This paper presents plate size effect on floor bearing strength of coal measures strata. Plate loading tests were carried out for varying size and shape of footing plates. The analysis was made for model scale footing. The load exerted by the plate on the floor strata was assumed to be uniforml...
