矿产资源储量估算边界线垂直纵投影角的计算方法、Excel程序编制及应用研究

地质技术人员在制作资源储量估算垂直纵投影图时,往往需要进行矿体边界、断层、边坡、受护体移动面(线状压覆)、侧伏线、矿界等投影,通常要制作多个剖面图,才能得到投影线的位置。这个过程费时费力,效率低下。该文通过计算的方法直接得到投影角,通过地面交点位置直接画出投影线,大大简化或省略或减少了有关剖面图件的制作过程,提高了工作效率,提供了计算方法和Excel计算程序,列举了计算实例。

Study on the Calculation Method of Vertical Longitudinal Projection Angle of the Boundary for Resource Reserves Estimation Programming and Application of Excel

In order to enable geological technicians to make vertical projection maps for resource reserves estimation, projection angles, such as ore body boundary, fault, slope, moving surface of protected body (linear overburden), lateral volt line and ore boundary can be obtained by calculating method. In order to get the position of projection line, it is usually necessary to make multiple section maps. This process is time-consuming, laborious and inefficient. In this paper, the projection angle is obtained directly by calculating, and the projection line is drawn directly by the position of the intersection point on the ground, which will greatly simplify, omit or reduce the process of making the section map, improve work efficiency, provide calculation method and Excel calculation program, and list calculation examples.
