Analysis of Russian Literature on Coal Batch Compaction by Stamping. 1. Technological Factors

The main trends in Soviet and Russian research on the compaction of coal batch by stamping (stamp charging) are identified, beginning in the twentieth century. Factor analysis indicates two main topics: 1) the influence of stamped coal batch on the coke yield and strength; 2) detailed study of the influence of the batch’s packing density and moisture content on the pressure required and also the influence of the fractional composition of the coal and the batch, which, in turn, determines the effectiveness of stamping, the technical characteristics, and the properties of the stamped cake.
