Volume:

Operation:

Target Products Limited designed, built and operated its own batch plant which was erected at the site.  

• Shotcrete Concentrate (a mixture of cement and all necessary admixtures) was brought to site in pre-dosed bulk bags.

• Gravel and sand available on site were dried and sieved to attain a recommended ACI N^o2 shotcrete gradation.

• Dry shotcrete was available to the contractor at all times from a 50 cubic yard silo erected just outside the mine.

• Shotcrete was taken into the mine in auger trucks operated by the contractor - trucks were gravity loaded at the silo in less than 15 minutes.

• The shotcrete plant was fully operational only 7 weeks after placing of the order.
