Traversing underground using wall stations is a relatively simple procedure in mine surveying. However, because of short sight lines and restrictive geometry of such surveys, procedures and considerations must be considered in order to minimise the potential to introduce and propagate large errors into the survey results. These considerations can be quite numerous, including where to position the setup, how to perform the resection, the number of resection stations and forward stations to employ, how many shots to be taken at each setup, whether a force centring traverse should be performed (where possible), and what should be included in the adjustment or check of the final coordinates. These factors can have a much larger impact underground compared to similar above ground surveys, and while there are a lot of experience and practices in place, there is no common standard or source for what is ‘best practice’ in industry.

This webinar, our speaker Dr Andrew Jarosz will focus on exploring some of the experiences and knowledge available, and collaborating with our own experiences with such surveying practices. It will cover some of the different configurations and procedures used, and investigate their effects on the propagation of errors through the survey and how they might be mitigated. This will include theoretical and simulated data sets, as well as practical surveys and experiences where available. The goal is to conclude with a discussion on personal experiences, and what procedures or testing you would like to see in order to draw conclusions on what is ‘best practice’ in the field.
