地形测量是地質勘探工作中一项重要的基础工程,所有勘探工程的摆布,钻孔、坑口的设计和定位,以及地质图填繪,矿产量計算等,都要首先进行测量工作并以地形图为依据。同时,在地质勘探阶段所测制的成果成图,还将被广泛的应用于矿山設計、建設和开采等各个时期。因此,测量工作必须正确的将地球表面形状按需要比例尺全面的反映在图紙上,以及正确的确定地面地下点綫間的相互关系位置。提出合乎各项建設质量要求的成果成图資料。从地质勘探工作对地形图的質量要求来说,是比較高的,因为地表地质工作是整个地质工作的基础,而地表的表现就是 Topographic surveying is an important basic project in geological prospecting work. All surveying works, drilling and pit design and positioning, as well as the filling of geological maps and mine output calculations, must be measured first and topographically. Based on. At the same time, the mapping of the results measured during the geological exploration phase will also be widely used in various phases such as mine design, construction and mining. Therefore, the measurement work must correctly reflect the shape of the earth’s surface on the drawings according to the required scale, and correctly determine the relationship between the underground ground and dotted lines. Put forward the results of mapping materials in line with various construction quality requirements. From the geological exploration work, the quality requirements of the topographic map are relatively high, because the surface geological work is the basis of the entire geological work, and the performance of the surface is
