Abstract: Routing a paste distribution pipeline can be a rather complicated three-dimensional puzzle. To 
reduce initial capital cost, the designer tries to use existing shafts, access ways, and boreholes. However, a 
poor pipeline layout can cause chronic operating problems and increase the total cost of the system. This 
may be due to high binder usage or power costs. It could be due to high wear rates that shorten the life of the 
pipelines or boreholes. It could be due to the line plugging or blowing the pressure relief on a regular basis. It 
could be a low paste transfer rate that limits how fast the stopes can be filled (and therefore mined). A low 
initial capital cost solution can quickly become a high capital cost solution if boreholes need to be replaced 
on a regular basis because they are plugged with paste or the casings have worn through.
A well laid out pipeline will be easy to operate and have the lowest total cost. That begs the question: �What 
does a well laid out pipeline look like?� To answer this, one needs to consider a few key concepts: costs, 
binder usage, paste flow behaviour, and wear.
