摘要
指出了在地形图上用传统方法连结的矿体界线存在着弯曲程度不够准确的问题,总结了倾斜矿体和走弯矿体界线在地表曲面上的弯曲特点平“连结方法,阐明了制约划定矿体界线的辅助点的各种因素,并举实例说明了其应用。
The conventional method for plotting the borderlines of ore bodies on topographic map is found not so satisfactory and accurate in representing the actual degree of curves. The curves showing inclined/curved-strike ore bodies on the earth surface are studied systematically as well as the method of connection to form borderlines. A new and more accurate method is thus suggested using several auxiliary control points. Influencing factors on these auxiliary control points for defining ore body borderlines are explained, with instances cited to show their applications.
