Advance Your Use with Mesh Tools – Part Two

By

This is Part Two of a series on using Mesh Tools in GEOVIA Surpac™. Part One introduced Linear Clearance Analysis and Deviation Analysis. Today’s post discusses cases where Linear Clearance Analysis and Deviation Analysis can be used.

Analyzing surface and underground designs to ensure they meet requirements for minimum separation distances can be challenging, time consuming and error prone. Incorporating core functionality developed by Dassault Systèmes, the Mesh Tools module offers a suite of advanced modelling tools that can help you analyse and manipulate triangulated meshes of solids and surfaces to achieve your modelling and design objectives. Let’s have a look.

Linear Clearance Analysis in Mesh Tools makes it easier to report on the closest separation distance between collections of spatial objects for safety analysis of underground and surface designs. This plays a key factor in maintaining safety standards by ensuring that underground cavities (stopes, declines, development headings, etc.) don’t approach closer than a minimum mandated separation distance.

Linear Clearance Analysis will compare solids, surfaces, polylines and drillholes in a matter of seconds and report the closest points between all pairs of objects being analysed. The results are shown graphically as construction lines and labelled with the separation distance. These specially coloured lines and markers depict the intersection of objects as a tabulated report with the exact coordinates of the points of closest approach and intersection.

As well as helping ensure safety standards are met, a mine geologist can now see how far the existing boreholes are away from a known ore body, what holes intersect the ore body being analysed and where exactly those intersections occur. This can help refine an existing drilling plan.

Ensuring open cut and underground excavations stay within an acceptance tolerance of designs is an important factor when ensuring the efficiency of the mining operation. If the excavation deviates from design by more than the allowed tolerance it is important to know, quickly, by how much, and where this is occurring so that remedial action can be taken quickly.

Deviation Analysis allows you to compare two solids or surfaces by plotting the relative differences between them in a colour coded map with corresponding value scale legend. This allows the engineer or surveyor to immediately understand the magnitude of the deviation between the two objects as well as identify where the deviation occurred.

This knowledge allows plans to address the deviation and bring the excavation back on track as soon as the survey has been completed to prevent expensive mistakes from occurring.

Another valuable use of Deviation Analysis is to compare an open pit excavation with old underground workings to determine areas of high risk that may be too close to the old workings.
