HYDRAULIC TRANSPORT OF PB ZN ORE FROM 450 M DEPTH TO SURFACE

At the present time hydrotransport is being applied in Czechoslovakia in the ore mining industry. The present state of research and the respective operating experiences are reflected in the results gained with the Kank ore mine transport-line in the Kutna Hora district, where Pb Zn ore with a 50 mm grain size is being transported to the surface from a 450 m depth. The paper deals with the hoisting scheme and operating technology--including the feeder system and solids specification--and discusses the reasons for the choice of alternative transport facilities. A short reference is made to the theory of vertical upward flow of heterogeneous mixtures which is one of the significant problems with the design of heterogeneous suspension transport systems for ore extraction.
