1972年第4期《地质与勘探》译载的《根据钻孔资料绘制中段地质平面图》一文,提出了根据斜孔资料绘制中段平面图的方法.当矿体在地表和深部的产状一致时,这种方法是正确的,因为偏斜钻孔往剖面上的投影方向与矿体的总走向基本一致.但是,野外工作的大量事实表明:受构造控制的矿床,往往由于若干构造体系的复合,使矿体产状发生局部或总体的变化.矿体在地表走向为北北西,到深部也可能变为北北东.地表矿体倾角较陡,深部倾角也可能较缓.
The article “Drawing the Middle Section Geological Plan According to Drilling Data” published by Geology and Exploration, No.4, 1972, put forward the method of drawing the middle section plan according to the slant hole data.When the ore body is consistent in the surface and in the deep, This method is correct because the direction of projection on the cross section of the borehole is basically consistent with the general trend of the orebody.However, a large number of field work have shown that the deposit controlled by tectonics is often due to the combination of several structural systems, The occurrence of local or general changes in ore body ore body in the surface north-northwest, to the depth may also become north-north east surface ore body steep, deep dip may also be slower.
