| 中文摘要: |
| 脉状金矿为非水平或非垂直(即倾斜,尤其是中度倾斜)状态时,垂直或水平投影均会产生较大的投影畸变,导致矿体的几何形态失真和矿体间的展布规律不明显。对产状相对稳定的脉状金矿建立以平均倾向和平均倾角为参数的平行矿体的投影面,借助这个投影面研究金矿体的空间特征和矿脉顶板构造面的起伏规律,实例说明平行矿体的投影方法与常规投影方法比较,能更多地显示矿体的空间特征与赋存规律。 |
| 英文摘要: |
| Projection of non-horizontal and non-vertical gold lodes is subject to geometric distortion and obscurity of distribution pattern of gold ore bodies,especially for the medium oblique ore bodies.On basis of parameters of average dip and dip angle for gold lodes with relatively stable occurrence is established a projection plane parallel to the gold ore body.By means of the plane are researched spatial characteristics and relief patrtern of the top structural plane of the ore body.The case study shows that projection onto the established plane is superior over the tradional horizontal or vertical projection in reflection of spatial characteristics and occrrence of gold ore bodies. |
