按倾角分类的各种煤层的英文翻译

根据倾角,中国将煤层分为近水平煤层、缓倾斜煤层、倾斜煤层以及急倾斜(In China, coal seams are divided in accordance with the degree of their inclination and called the almost flat seam, the gently inclined seam, the inclined seam and the steeply inclined seam)。依据采矿设计手册,倾角<8°为近水平煤层,8 – 25°为缓倾斜煤层,25 – 45°为倾斜煤层,而急倾斜煤层是指倾角大于45°的煤层(steeply inclined coal seam - said of coal seam with a dip of from 45 to 60°)。

下面是按倾角分类的各种煤层的英文翻译:

近水平煤层 almost flat coal seam

缓倾斜煤层 gently inclined coal seam

倾斜煤层 inclined coal seam

急倾斜煤层 steeply inclined coal seam或steeply dipping coal seam

有些学者还把“急倾斜煤层”翻译成steep coal seam,highly dipped coal seam,highly-pitched coal seam,等等。笔者认为,最地道的翻译应为 steeply inclined coal seam 或 steeply dipping coal seam。
