ABSTRACT:
An apparatus for multiple injection of slurry from a plurality of mine faces or other slurry sources into a slurry line comprises a unique method and apparatus for connecting each slurry injection point to the main slurry line by using a vortex junction apparatus. The vortex junction apparatus provides a means for passing the slurry from one junction point to the next junction point and at the same time provides a means for merging slurry from each injection point into the main slurry line. The junction apparatus also provides a source of water for each injection point, thus eliminating the need for a separate source of water. One embodiment provides for a junction where the main and branch slurry lines are at nearly the same pressure while a second embodiment provides for a junction where the branch slurry line is at a substantially lower pressure than the main slurry line.
