Abstract: Through the research filling pipes two phase flow of the basic theory, the filling pipe filling in the settlement of rules and forms of exercise was analyses, huangshaping ore critical flow velocity and two phase flow hydraulic gradients was calculated.Filling flow patterns and rheological properties in the pipe of filling body was analysis.Reynolds number as a numerical calculation pastes the theoretical basis of the flow pattern was choose.ANSYS finite element software Flotran fluid mechanics module was used in the numerical calculation.it provides theory support for huangshaping ore deep filling pipes.

Key words: Deep mining, Filling system, Pipe line transportation, Numerical simulation
