摘要
根据GPS在煤田地质勘查控制测量工作中的实践,阐述了GPS在控制网的布设方案和作业方法。数据处理和精度分析表明,GPS观测数据质量高,控制网平差后点位精度达到0.28cm,满足煤田地质勘查测量工作的需要,为煤田地质勘查工作提供了可靠的技术保障。
According to the GPS control survey in coal field geological exploration work in practice, elaborated the GPS in control net arrangement scheme and operation method, data processing and precision analysis show that, the GPS observation data is accurated, control network adjustment after the point position precision of 0. 28 cm, satisfy the coal field geological exploration measurement work required, as the coal geological exploration work provides a reliable technical support.
