Abstract
The pipeline from two hinge the sites located along a face, and two telescopic sites on lines is synthesised. Influence of a design of the hinge on losses of pressure and the central corner divergence of hinge sections on effort of its reduction is analysed. The diagramme of communication of width dredging strips of coal with capacity of a layer is offered at the set level of losses of pressure of water in hinge the pipeline and effort of its reduction.
