{Charleston, West Virginia}...The federal Mine Safety and Health Administration says it conducted a one-day inspection blitz at 43 Alpha Natural Resources mines in in West Virginia, Virginia and Kentucky Wednesday, targeting former Massey Energy operations. MSHA spokeswoman Amy Louviere says the blitz followed a recent incident involving a burning conveyor belt at Alpha's Road Fork No. 51 mine near Pineville in Wyoming County. That mine was cited for serious and substantial violations. Louviere says no violations issued this week were as serious as those at Road Fork. Other results will be released later.
