近年来,利用钻孔岩心轴角换算地层(岩、矿层)产状的问题,引起国内外地质工作者普遍关注.按照笔者的理解,所谓岩心轴角系岩心轴(即钻孔轴)与地层面所构成角度之总称.如所周知,它既可用岩心(钻孔)轴与层面本身所夹之锐角表示,亦可用该轴与层面法线所夹之锐角表示(图1).对此二角曾被赋予不同的名称(表1).笔者以为,将层面法线与岩心(钻孔)轴所夹之锐角称为法轴角,既立意确切,又简单易记.与其对应,层面本身与岩心(钻孔)
In recent years, the use of drilling core shaft angle conversion of formation (rock, ore) problems caused widespread concern of geologists at home and abroad. According to the author’s understanding, the so-called core shaft axis of the core shaft (ie, drilling shaft) As it is well-known, it can be expressed by the acute angle between the axis of the core (drilling) and the plane itself, or by the acute angle between the axis and the plane normal (Figure 1) The angles were given different names (Table 1) .In the opinion of the author, the acute angle between the normal of the layer and the core (borehole) axis is called the normal axis angle, which is both exact and easy to remember. Correspondingly, the level itself And core (drilling)
