Heavy rain and flooding has halted production at a number of central Queensland coal mines.
The Queensland Resources Council (QRC) says falls of up to 250 millimetres have been recorded at some sites, with about 20 mines now releasing water.
In 2011, flooding cost the industry $7 billion in lost production.
QRC chief executive Michael Roche says this year's flooding is not as bad.
"There's no doubt that there's many mines that received rainfall in the order of 200 to 250mm of water," Mr Roche said.
"Unfortunately for some mines that probably added to their unwanted excess water problem.
"The good news is that Abbot Point and the Hay Point ports and the Goonyella system are open."
Mr Roche says the mines will be keen to resume delivery of coal as quickly as possible.
The torrential rain has disrupted haulage operations in the Moura and Blackwater systems.
The QRC says it is too early to say how much damage has been done to the coal freight network.
Haulage along the Goonyella line to Hay Point and Abbot Point are unaffected.
