数字地调系统中探槽编录及成图方法与技巧

Digital Control System in Trench Logging and Mapping Methods and Skills

地质调查与探矿工程是地面地学空间数据获取主要方法之一。中国地调局研发的数字地质调查信息综合平台(DGSInfo系统)使传统的工程编录发生了巨大的变化。探槽编录是地质调查工作的重要组成部分,DGSInfo系统使探槽编录全面实现了计算机化。探槽素描图的制作包括探槽野外原始数据收集整理、探槽素描图成图两个步骤,本文在介绍探矿工程系统中探槽编录主要构成的基础上,对探槽素描图的成图过程及探槽平面投影进行了较为详细的论述,并着重介绍如何将探槽形态投影在平面图上。

Geological Survey and exploration engineering is one of the main methods to obtain the ground of geo spatial data.China Geological SurveyResearch and development of digital geological survey information integrated platform （DGSInfo system） to catalog works great changes in traditional. Trenches catalog is an important part of the regional geological survey and mining geological survey work to expose important geological boundaries, understand the scale of the mineralized alteration zone structure, morphology, occurrence, change in taste, etc., and provide the basis for the arrangement of drilling. Its use has changed the traditional method of data collection trenches catalog, so that data collection in the field catalog realization of the digital and computer in the room to achieve a mapping automation. Trenches catalog system is fast, accurate advantage, can automatically generate trenches sketch, reduces indoor workload, improve the accuracy and efficiency of the trenches sketch produced. Based on the introduction of exploration engineering in the system catalogis mainly composed of a trench, the trench sketch drawing process and the projection groove plane are discussed in detail, and emphatically describes how the trench shape projection on the plane.
