For the purpose of developing of the coal blending technology applied to various kinds of low rank coal, we investigated the inhibitory influence of kind and particle size of low rank coals on the dilatation of high rank coal. The main findings summarized below.
(1) When the low rank coal whose dilatation value is extremely low is added to high rank coal, the inhibitory influence on the dilatation of high rank coal becomes high. And as the particle size of low dilatation low rank coal becomes finer, it becomes higher.
(2) When the low rank coal is added to high rank coal which starts softening at low temperature, the effect of the difference in kind and size of low rank coal on inhibitory influence is not so large.
