CHARLESTON, W.Va. (AP) The latest in the federal trial of Don Blankenship, former CEO of Massey Energy. All times local:

12:30 p.m.

Prosecutors want the judge to tell jurors to keep deliberating if they continue to say they're deadlocked in the federal trial of ex-Massey Energy CEO Don Blankenship.

In a motion filed Wednesday, prosecutors asked U.S. District Judge Irene Berger to read another set of instructions if jurors come back deadlocked. They have twice indicated they can't agree, including once Tuesday.

The prosecutors in Charleston, West Virginia, want the judge to give the jurors guidance similar to what she told them Tuesday.

The proposed instructions would tell jurors there's no reason to believe a new trial would offer better evidence or field a better jury. They would also encourage jurors in the minority to consider the majority's view, and vice versa, without giving up a conscientious conviction, and would tell jurors to keep in mind the value of a unanimous verdict.

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.
