Mining Method

https://www.youtube.com/watch?v=whw1GTVEXW4Jet Boring SystemIt is type of Backfill MethodOre body is frozen. A drill is drilled into the ore body. The jet cuts the ore body. After completion the cavity is filled with cement.

Showe video at 40 seconds7Ore Body and mine development

The ore body is 480 meter deep.

According the ore body . Room and pillar would be the best option

miners spend about a year freezing the rock with ultra-cold brine. Then they bore through the rock from below using high-pressure jets of water that move at 1,600 kilometres an hour through a nozzle. The water flow is powered by four pumps using 800 horsepower each, or the equivalent of about six semi tractorsA slurry of uranium ore and water is flushed down into the tunnel from the ore body above, where more water is added before everything is pumped into storage tanks. The ore is then broken down in an underground mill and transferred to a thickener. Finally, it is pumped to the surface and shipped to the nearby McClean Lake mill for processing.

ChallengesPoor Ground ConditionA lot of Water Two Floods2006200833 years to move from discovery to production!

Flooding 2006 and 2008 flooding occurredReason: More water coming in then it can be pumped Reason.drilled and blasted too close to the unstable sandstone in the Athabasca Basin, Solution:Cameco hired a mini remote-controlled submarines to detect water flows and radiation, Learning from failures:2,550 cubic metres of pumping capacity at the mine (double)More Careful drilling and blasting ( away from water)Bulk Freezing
