There was no specific details on how Thor did it. It was one of the many abilities that Mjolnir offers him, though logic would dictate that he would use this ability more often against other beings since it is not just mysitcal fields. It is more than likely a one-off ability used by the writer of the issue it came from because I can't recall Thor using that ability a second time.
