Abstract
A review was made of two Russian books and a chapter from a third book dealing with pipeline transport of coal. Emphasis was placed on hydrotransport of coarse coal in underground mines or surface pipelines. The book reviewed were "means of increasing the effectiveness of hydrotransport," by V. N. Porkovskaya (1972) and "parameters and modes of hydraulic transportation of coal," by V. V. Traynis (1970); and the chapter was from the book "hydromechanization of opencast working," by g. A. Nurok (1970). All three are unique and useful additions to the world literature on hydrotransport. The traynis book reveals the development and results of circular wheel stands tests to simulate hydrotransport in horizontal pipes, which is a potentially outstanding contribution to slurry pipeline technology. Graphical data and equations are presented which suggest that headlosses for coarse coal can be predicted with good accuracy for pipe sizes up to 14 inches in diameter. Wheel stands permit tests for pipe wear and lump degradation without recycling coal through pumps.
