Second miner injured at Saskatchewan potash mine.

A miner is being treated in hospital after an accident at the Agrium Inc. operated Vascoy Potash Mine in Saskatchewan Province, Canada, on Sunday 21 August 2016. The name of the miner, the nature of his injuries and the cause of the accident have not yet been released, but it is understood the man was airlifted to hospital for emergancy surgery, and is described as being in a serious, but non-life-threatening condition. The incident is of particular concern as it is the second such incident at the mine this month; on Monday 8 August miner Chad Wiklun was rushed to hospital after becoming trapped in equipment and later died of his injuries.

There are large reserves of potash (potassium salt), an important mineral in the production of commercial fertilizers, buried beneath the plains of southern Saskatchewan, though accessing these has proved difficult for mining contractors. The potash-bearing deposits are at their shallowest along a line that runs southeast from Saskatoon to Regina, where they are buried at a depth of approximately 1000 m. The deposits get deeper to the southwest of this line, reaching 1600 m at Belle Plaine (between Regina and Moose Jaw) and as deep as 3000 m bellow Montana and North Dakota. This depth in itself is not an insurmountable problem, but the deposits are also beneath the Blairmore Aquifer, at a depth of 400-600 m in the Saskatoon/Regina area, which needs to be sealed of by mining engineers sinking shafts to the potash deposits in order prevent flooding (water bearing strata can overlie dry strata as long as there is a water-impermeable layer, typically clay, in between).
