In order to improve roof support capacity of floor, baseplate of sufficient size can be used in order to prevent prop from sinking into floor; determination of optimum size of plate can be achieved most rapidly by testing floor with dynamometer prop, although limited working loads of existing props of this type make it necessary to extrapolate results of tests; method of testing mine floors; test results; softening effect of water on coal seam floors; effect of brat thickness on elastic floor.
