Abstract
Overview ?Overview of the mining area ?Description of the mining phases ?Risk assessment ?Design criteria and description for freeze drifts ?Freeze wall design ?Raisebore mining Four Main Phases: 1.Development of freeze drifts on the 520 and 590 levels 2.Freeze drilling and ground freezing to isolate the Zone 4 North ore body from water bearing sandstone. 3.Develop raisebore and extraction chambers including access drifts and ramps under freeze protection. 4.Start raisebore production mining of the Zone 4 North area.
