Britain has approved the first deep coal mine in 30 years, to supply coking coal to steelmakers.

英国已经批准30年来首个深井煤矿项目，向钢铁制造商供应焦煤。

Frick's entrance into the combination gave the concern an unlimited supply of the highest grade of coking coal.

弗里克加入合并后， 公司可以无限供应最高品位的炼焦煤。

In 1709 Abraham Darby, a local merchant, leased a foundry and fed the furnace with coking coal, rather than charcoal made from wood.

1709 年， 当地商人亚伯拉罕·达比 (Abraham Darby) 租用了一家铸造厂，并用炼焦煤而非木材制成的木炭为熔炉提供燃料。

This material, so called because its surface is riddled with holes, is then refined into steel using an electric-arc furnace, which dispenses with coking coal.

这种材料因其表面布满孔洞而得名，然后使用无需炼焦煤的电弧炉精炼成钢。
