Once familiar with the RDE, it is important to modify your approach to the fieldworkįor software as powerful as Terramodel RDE, an orderly approach is essential to the successful reduction of data Check Surveyĭuring the check survey of the Viking Decline, a total of 1778 observations with 276 unknowns were used to re-calculate the positions of all wall stations in the decline.Study up on Least Squares theory as it applies to surveying.Try to understand the messages and warnings.Give some time to get familiar with what the RDE is trying to do.Having heard of Terramodel users being frustrated by the RDE, I believe the solution is to: This data is stored and downloaded to the Terramodel RDE and added to the previous data, thus building up a huge mathematical matrix of observations and tightening up the network. As with the placement of wall stations within a tunnel, each time a survey is conducted there are multiple observations made to as many stations as practical. It is very useful to be able to build up a control network and improve the quality of the data within that network during the course of a project. Gradually my knowledge and skill with Terramodel has increased to a point where I no longer pre-process everything in Geocomp. Having been a Geocomp user since 1992, I first began using Terramodel in 1999. This approach requires the use of sophisticated surveying software to complement the fieldwork.The use of software positioning removes some of that level of personal confidence. Setting up on (or under) a previously surveyed point gives the surveyor a sense if logic and geometric understanding of the job at hand.With the use of on-board instrument and calculator software this process is made virtually hassle free. This was was once a tedious and complicated mathematical process.

The survey team needs less equipment to install wall stations than roof stations.There is no need to wait for assistance of other workers.There is no need for lifting gear to access the backs (roof).With this check I hoped to increase my confidence level of the use of wall stations as there are many advantages for this approach: Although wall stations have been used successfully in mines for a number of years, the widespread acceptance by surveyors of this approach has been limited.Īs the surveyor responsible for the mining of the Viking Decline, I was anxious for a check survey, especially after the development progressed around two corners and out of sight of the portal. Survey control at the Viking Decline near Zeehan, Tasmania has been maintained with the use of wall stations rather than the conventional roof station approach.
