1) bearing
[英]['bɛəriŋ，'beərɪŋ] [美]['bɛrɪŋ]
煤层走向;轴承
3) cod
[英][,si: əʊ 'di:] [美]['si 'o 'di]
轴向轴承
4) semi-confined coal seams
承压煤层
1.
based on the theory of gas flow in confined coal seams and taking into account the characteristics of gas flow in semi-confined coal seams,the paper deduced the differential equation of gas flow in semi-confined coal seams with both isotropic and anisotropic permeability,thus built the mathematical model of gas flow in semi-confined coal seams.
当煤层上覆岩层和底部岩层为致密岩层、透气性极小时,可以认为完全不透气,则含瓦斯煤层为承压煤层;当煤层上覆岩层和底部含有一定的裂隙,其渗透系数与含瓦斯煤层相比虽然很小,但仍然有少量瓦斯通过透气性较低的上下岩层流入或流出含瓦斯煤层,此时含瓦斯煤层为半承压煤层。
5) strike fault
走向断层
1.
Influence of strike fault to gently inclined narrow orebody and mining countermeasure;
走向断层对缓倾斜薄矿体开采的影响及开采对策
2.
Nevin to determine the stratigraphic duplicate and incompletement caused by the strike fault,the method is complicated and trivial.
构造地质学对走向断层造成的地层重复，缺失一直沿用Ｃ。
6) strike direction of strata
岩层走向
补充资料：走向
地质构造面和水平面交线的方向。是地质体(如褶皱、断层、岩层等)在空间赋存状况的一个重要参数，表示地质体在地面上的延伸方向。按不同的对象分别称为岩层走向、断层走向等。
