A statement from his lawyers said: "Mr Whittall is a coal miner. He comes from a coal-mining town and has worked in underground mines all his life.
"He maintains that he would never do anything to put men who worked with him at risk - and Mr Whittall will fight being scapegoated now."
The charges he faces relate to the operation of the mine about November 19, the day of the first blast, but his lawyers say that at that time he was in Wellington and handling corporate, not operational, matters.
He is accused of failing to take all practicable steps to ensure the safety of workers at the mine.
Despite having the chance to leave the company and New Zealand after Pike River Coal went into receivership, Whittall stayed and assisted the Department of Labour investigation.
"He is deeply saddened by the Department of Labour's actions and intends to vigorously defend all charges laid against him, " said his lawyers' statement.
Whittall said he would like to comment more, but had been advised against it.
As well as being the public face of the disaster, Whittall spoke to the families each day to update them on the bid to get their loved ones out of the mine. And he told the families the miners would not be coming home.
When the names of the missing were read out at a press conference, emotion got the better of him.
"I know all of the men. I've employed all of the men. When I look down the list, I can see the faces of everyone on the list," he said.
Pike River Coal said it would not comment on charges against it while the case was before the courts, and VLI Drilling said the basis for allegations against it had not been disclosed so it could not give a response.
The Department of Labour said the investigation was the most complex in its history, with more than 200 interviews completed and 15 investigators working on the case at its peak.
The royal commission of inquiry into the tragedy resumes in Greymouth next week.
