Underground Paste Fill

Paste fill is a method developed over the past 15 years simply to fill the mined out voids underground and to stabilise ground support, thus allowing for the extraction of high grade pillars that, in turn, increase the resource of the mine overall.

Specialised Engineering Services is one of the pioneers in the design and installation of paste fill piping underground and the installation of bore hole casings to allow the paste to be gravity fed to a given point underground.

We have also designed a shotcrete barricade that can be pre-assembled and placed in the drive with an integrated  tool carrier.  This method is a proven solution to minimise the amount of paste required to fill an open stope as the barricade can be placed in the drive within two metres of the stope.

These barricades have been successfully installed at Kanowna Belle WA and Lady Loretta Qld.
