Hold the line
28 February, 2013
Maurice Jones points out that modern surveying methods now rely heavily on electronic instruments and automatic data collection and analysis through advanced software packages. While these should not detract from understanding of basic principles, the potential for time and staff savings, plus increased understanding of the objects being surveyed, is substantial

Mitigation and alternatives: making hand mining better
26 September, 2011
A current trend in tunnelling, as in many other industries, is against manual labour, but in many situations hand mining seems the logical first choice until one considers the hazards involved that are arguably greater then those associated with large-section tunnelling. Maurice Jones checks on the current status of the activity, mitigation to improve hand mining, and the alternatives offered by some equipment manufacturers.

From the ground up - to project control
14 March, 2011
What happens when underground construction practice doesn’t follow design theory? How can engineers find out what is actually happening with accuracy to reduce risk? The principles of structural monitoring have been known for many years but technical developments in instruments to test ground conditions in situ have increased reliability and reduced cost to such an extent that the wealth of information available has required new thinking in data handling, analysis and presentation. Maurice Jones checks with some leading participants on how data is now collected handled and used, plus how improvements might come about
