Transportation of water-based slurry in an open furrow, launder or streamJ.P.F.CharpinauthorT.G.MyersauthorM.LombeauthorP.de HillauthorThe transport of large boulders in a furrow from a mining area to a nearby pond was considered. The furrow is filled with a mixture of water and soil particles flowing down to the pond at a very high velocity. Due to operating constraints, the slope of the furrow is reduced progressively. A formula is derived, relating the slope of the furrow and the composition of the fluid to the maximum size and shape of the transported boulders. The characteristics of the boulders carried all the way down to the pond may then be determined.Energy and utilitiesMaterialsNone/Other2004Study Group Report
