The utility model relates to a (b) increase device that hinders pressure regulating in filling ground paste pipe -line transportation (b) in the little times of high pressure head mine filling system of line to the too big problem of ground paste pipeline transport local pressure of filling is solved to the mode that increases the resistance loss of ground paste in the pipeline. The input and the output that increase the device that hinders the pressure regulating are all connected on the pipeline of ground paste is filled in the transport, the level who increases the input of the device that hinders the pressure regulating is higher than increase the output of the device that hinders the pressure regulating, the utility model discloses process flow is simple, simple to operate, and the inside mortar flow state of pipeline is stable.
