EFFECT OF ANTHRACITE AND GAMMA RADIATION AT AMBIENT REMPERATURE ON THE SUBSEQUENT PLASTICITY OF BITUMINOUS COALS
Special Research Report SR-15 Three anthracites blended with three bituminous coals (-40 mesh held in closed containers) have been irradiated in the University nuclear reactor to a total dosage of 3.8 x 108 rads in the presence of an atmosphere of air. The amount of oxygen in contact with the coal under these conditions was approximately 0.2 cc. at S.T.P. per gram of coal. Fluidities of the irradiated coal blends were measured using a Gieseler plastometer and compared with fluidities of the unirradiated coals. For bituminous coal Y, addition of 20% anthracite did not decrease the fluidity below that for the addition of 5% anthracite. Irradiation of the coal blends did not result in any appreciable fluidity change; however, irradiation did result in a decrea.se in fluidity for coal Y. For bituminous coal z, a decrease in fluidity was found for 5% anthracite addition and a still greater decrease for 20% anthracite addition. The effects of radiation on coal Z and the blends are similar to that of coal Y. For coal M, addition of 1% anthracite resulted in an increase in fluidity, follo'Wed by a decrease when 3 and 5% anthracite were added. However, in contrast to coals Y and z, radiation resulted in an increase in fluidity of the coal blends.
