ARLINGTON, Virginia — Federal inspectors issued 139 citations and three orders at U.S. mine operations in June.
The Mine Safety and Health Administration says the inspections were conducted at 10 coal mines and five other mines in 11 states, including Kentucky, Virginia and West Virginia.
The impact inspections began in 2010 after the Upper Big Branch mine explosion in West Virginia killed 29 coal miners. Since April 2010, MSHA has issued 14,561 citations and 1,250 orders.
Mines targeted by the inspections are those that have compliance concerns or poor compliance history.
