The Long Hole Plug (LHP) Features

The shell component works similar to a friction anchor holding the long hole plug in place

If the drill rod should fall they strike the tapered core driving it into the shell. This transfers the vertical forces horizontally into the rock mass.

Industry accepted solution

The long hole plug is used in over 35 mining operations around the world.
