CHARLESTON, W.Va. (AP) - Jurors have started their eighth full day of deliberations in the trial of ex-Massey Energy CEO Don Blankenship.

CHARLESTON, W.Va. (AP) Jurors have started their eighth full day of deliberations in the trial of ex-Massey Energy CEO Don Blankenship.

The jury resumed work Wednesday in U.S. District Court in Charleston, West Virginia.

Jurors told the judge Tuesday they remained deadlocked, but were instructed to keep trying.

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.
