Gleision deaths: 'Possible' mine check found no water
Water which flooded a mine killing four workers may not have been there the day before when the area was inspected, a jury has heard.
Geologist Dr Alan Cobb said it was "possible" and "probable" that the water collected after manager Malcolm Fyfield inspected it.
He told Swansea Crown Court that water could have rushed in from an older Victorian mine underneath Gleision drift mine.
Mr Fyfield and owners MNS Mining Ltd deny manslaughter charges.
David Powell, 50, Charles Breslin, 62, Philip Hill, 44, and Garry Jenkins, 39, drowned when water gushed into the area they were working in after they blasted into a flooded old section of the mine.
