摘要
运用导线分层次逐步布设控制点、测距与视距测量相结合布设基测点的方法 ,解决通视困难的金矿区布设土壤地球化学测量规则测网效率不高、精度低的问题。使用该方法 ,数据大大减少 ,便于计算机随机运算、检查、平差 ,也便于随时发现问题随时纠正。在河南朱庄金矿区 1∶1万土壤地球化学测量工作中 ,各项技术指标均符合规范要求 ,与传统方法相比 ,节约一半以上工期 ,返工率低。该方法建立在有先进的测量仪器和先进的计算工具基础上 ,仪器越先进 ,方法的优势越明显。
Lay control point gradually in different level by traverse and lay base point by combine the ranging and stadia survey,the problems of low effect and precision in laying out soil geochemistry survey regular survey grid in unvisibility gold mining area are solved.By the method, the data was greatly reduced,it helped the computer to calculate,check,balance randomly and also helped to find errors and correct them immediately.In process of the 1∶10 000 soil geochemistry survey in the Zhuzhuang gold mining area of Henan,all technical indexes fit the requirement well.The method has shortened half of working period and decreased the ratio of do over again in comparison with the traditional method.The method is based on the advanced survey instruments and computers,the more advanced the instruments will be,the more obvious the advantages of the method will become.
