According to my bible - US Bureau of Mines "A Dictionary of mining, mineral
and related terms" 1968 (kindly liberated by a buddy from a closing
Yorkshire chemical plant) - a definition of fork: -
"To pump water out of a mine. A mine is said to be in fork, or a pump to
have the water in a fork, when all the water is drawn out of the mine"
source: Fay, Albert H. A Glossary of the Mining and Mineral Industry.

Hope this helps
