Nationalists are concerned that chinese firms are increasingly buying not just coal , but collieries as well .

民族主义者正在关注越来越多的中国公司不但购买煤炭，而且开始购买煤矿了。

On the orders of the central government , linfen was closing down small , illegal collieries and the worst-polluting factories .

在中央政府的要求下，临汾已经关闭一些小型，非法的煤矿和重污染工厂。

Over the years , I have talked to black-faced miners at the mouths of illegal pits , descended deep down the shafts of huge state-run collieries , consulted labor activists , and interviewed mine owners and policymakers .

多年来，我曾在非法矿井口和黑色面孔的矿工们交谈，下到国有煤矿深处，咨询劳工权益活动家，采访矿主和决策者。

Collieries destroy arable land and grazing pastures , erode topsoil , worsen air and water pollution , increase levels of river sediment ( raising the risk of floods ) , and accelerate deforestation ( especially if the coal was used to make charcoal ) .

煤矿破坏耕地和牧场，侵蚀土地，使得空气和水污染更加恶化，增加了河流泥沙（进而提高洪水风险），加速森林砍伐（尤其是当煤炭用来制造木炭的时候）。

Today the coal industry in britain is on the decline , the number of miners , collieries and the total output have been falling .

如昔的英国煤矿业衰退，从而导致矿工、煤矿的数目和总产质皆大大降低。
