Massey Energy expects to complete construction and restart operations earlier than anticipated at its Bandmill preparation plant in West Virginia, US.

The Zigmond Processing plant, which was destroyed by fire on 27 August last year, could start processing coal again in September.

The facility, when fully operational, will have a processing capacity of 1,200t an hour and will service four underground mines producing metallurgical coal and two surface mines producing steam coal.

Meanwhile, Massey Energy’s Upper Big Branch mine in West Virginia is still being investigated by US federal regulators for the blast that killed 29 people last month in a worst US mining disaster.
