CHARLESTON, W.Va. (AP) Jurors are resuming deliberations in ex-Massey Energy CEO Don Blankenship's trial.

The jury is slated to return to work Thursday in U.S. District Court in Charleston, West Virginia.

Jurors have said twice they couldn't agree on a verdict. They have deliberated for all or part of nine days.

Blankenship is charged with conspiring to break safety laws and defrauding mine regulators at West Virginia's Upper Big Branch Mine and lying to financial regulators and investors about safety. The coal mine exploded in 2010, killing 29 men.

Prosecutors contended that Blankenship was a micromanager who meddled in the smallest details at the mine and cared more about money than safety.

Blankenship's defense team said the government offered no evidence he was involved in a conspiracy.

His trial began Oct. 1.
