The Construction And Application In Mine Surveying CORS System

China has vast territory, abundant mineral resources, but most of the mineralresources are buried in mining or underground, leading to great difficulties formineral resource predictions. With the continuous development and progress inmeasurement technology, RTK technology and GPS satellite positioning system hasbeen gradually applied to engineering measurements, providing accurate positioninginformation for mine survey. The CORS system integrates network technology,computer technology and wireless communication technology, and can realize thedata rapid acquisition and stable transmission, making it possible to measure the minequickly and accurately. The CORS system has been widely applied to environmentalmonitoring, surveying and mapping, vehicle navigation, urban planning and landcadastre management, etc. This paper elaborates the application of CORS system inmine surveying.Mainly taking the mine in Jixian as an example, this thesis first introduces theresearch background and significance, composition and working principle of theCORS system, providing a theoretical basis for the construction of Jixian mine CORSsystem. Then according to the actual circumstances of the Jixian mine, we completedthe CORS system, clarified the standards and requirements of the construction of thesystem. According to the construction of a good CORS system to complete a surveyof Jixian mine, and through an analysis of the collected data, we test and verify thereliability of CORS system operation system in the operation process of all kinds oferror, and provide the reference for system improvement. The outside precision ofCORS system in jixian mine surveying can be controlled in the range of±1.4cm inthe X direction,±1.2cm in the Y direction,±2.0cm in the H direction. The insideprecision of CORS system in jixian mine surveying can be controlled in the range of ±0.6cm in the X direction,±0.8cm in the Y direction,+1.5cm in the H direction.System has high stability and precision accuracy, and can completely meet therequirements of mine survey.
