The Application Of GNSS Technology In Mining Area Control Survey

Conditions due to the limited measurement techniques,traditional engineering control network commonly used theologize,total station,level,measuring equipment DME and other conventional measurements to establish the side-netting,corner mesh nets or other forms of angular measurement and control network,thereby leading to a heavy workload,long operating time,climate and environmental conditions affected significantly.With the development of GNSS satellite positioning technology,the mapping industry also had a profound technological revolution.GNSS measurements used in a wide range of high-precision control network,urban control network,the establishment of engineering control networks are increasingly common,have gradually replace traditional wire measurement and triangulation methods to establish control network,especially in the mountains mine surveying,mapping the river,pipelines and tunnels through measurements measuring more widely.Due to the terrain,the mountains mine surveying,mapping rivers,pipelines and tunnels through measurement survey control networks mostly in the form of unconventional layout,and many across the mountains and rivers,and given the relatively small neighborhood known point,to control network deployment,error control and test zones great job problems,so how to improve the accuracy of the results and economic benefits has become the focus of attention.In this paper,Guangdong Province,northern Guangdong mine GNSS control network measurement projects,explains how to use GNSS technology to create a mining engineering control survey network,elaborated mining engineering control measurement error in the GNSSnetwork deployment systems exist in the process,and the corresponding analysis;while this paper deal with scientific analysis software-HGO data processing software focuses on data acquisition and processing carried out a detailed analysis of the content and results of the research include: mine GNSS control survey network engineering design,select a coordinate system,the initial data verification,data collection,data formats and conversion,baseline solution and network adjustment.Finally,a detailed analysis of project examples,further demonstrates the continued research and the direction of research.
