Monaghan subsidence: Safety reports provide a mine of information

For weeks before subsidence destroyed a GAA club in Co Monaghan, between five and 11 million litres of water per day flowed into the mine beneath, says Caroline O’Doherty.

Between five and 11 million litres per day of water poured into an underground mine before a subsidence in Co Monaghan last year, and did so for weeks after the problem was discovered.
