The company said that the mines are being closed to align production and inventories following drop in coal prices.

Teck Resources will halt operations for three weeks but the company said that it will not affect the contracted and committed coal sales.

The company has decided to cut coal production for third quarter of 2015 by 1.5 million tonnes (Mt) to 5.7 Mt.

With the reduction, the company’s annual production is expected to be around 25 – 26 million tonnes.

The Canadian miner also said that it will further chalk out production adjustments depending upon the market conditions.

Teck Resources CEO Don Lindsay said: "Rather than push incremental tonnes into an over-supplied market, we are taking a disciplined approach to managing our mine production in line with market conditions.

"We will continue to focus on reducing costs and improving efficiency to ensure our mines are cash positive throughout the cycle and well-positioned when markets improve."

The company’s cost reduction measures undertaken previously have helped it save more than $640m till now.
