浅谈RTK在矿区测量中的应用

RTK测量技术因具有作业精度、作业效率高等明显优势，被广泛应用于矿区测量工作中。宁东煤田梅花井井田．总测量面积约70km^2，测区内沙漠较多．原有控制点破坏严重，采用常规测量手段施测十分困难，为此采用RTK技术，并建立了精度高、布局合理的矿区控制网。控制网由已知点4个，未知点15个组成，共处理基线65条。通过对控制网进行技术分析，发现RTK测量的各项指标均优于规范要求。结合GPS RTK技术在该矿区测量中的应用实例．指出RTK技术从基准站与流动站的设置至数据检验各程序中应注意的问题，并认为RTK技术是矿区测量工作的优先选择。

A Superficial Discussion on Application of RTK Technique in Mine Area Surveying

Since the obvious predominance of high operating accuracy and efficiency, the RTK surveying technique is widely used in mine area surveying. The Meihuajing minefield in the Ningdong coalfield has total surveying area about 70km^2, because of many sand dunes in the area, bring about serious destruction of original control points, operations of conventional surveying means are very difficult. Therefore, RTK technique is used, and mine area network of control with high precision and rational layout established. Network of control is composed of 4 known points, 15 unknown points, and processed 65 baselines. Through network of control technical analysis, has found that various indices surveyed are all excelled code requirements. Combined with GPS real time kinematic technique application examples in mine area surveying, pointed out attention should be paid to RTK technique issues from reference station and roving station setup to each procedure of data validation, and considered that the RTK technique is the preference in mine area surveying.
