Collapse of pillars as result of mining operation 'probably reason' for sinkholes in rural Monaghan

The collapse of pillars as a result of recent mining operations has been cited as the "probably reason" that a large sinkhole opened on the grounds of Magheracloone GAA Club in Monaghan.

An independent technical report to investigate the possible causes of the subsidence identified a "unique and complex" set of circumstances as being the most likely cause.
