STORAGE METHOD OF REFINED COAL AND COAL WITH VARIABLE PARTICLE SIZE Russian patent published in 2017 - IPC C10L9/00 B65G3/02 B65G63/00 

Abstract RU 2624445 C2

FIELD: mining.

SUBSTANCE: invention describes the method of storing the refined coal, where the method includes the briquettes forming step from the refined coal, the briquette crushing step and the granular coal stacking step, containing the refined coal in which the ground product produced during the milling step is used as at least a portion of the granular coal. The granular coal contains the particles, having a diameter not exceeding 10 mm, in the amount of 50 wt % or more, wherein the granular coal contains particles, having the diameter not exceeding 1 mm, in the amount of 25 wt % or more, and particles, having the diameter, not exceeding 0.15 mm, in the amount of 7 wt % or more.

EFFECT: development of the refined coal storage method, which is cost effective and due to which the prevention of stacks spontaneous combustion becomes possible.
