Machinery and equipment scanning is providing a whole new aspect on mine site maintenance.<\/span><\/em><\/p>\n

3D laser scanning has been slow to make an\u00a0appearance in the mining industry.<\/p>\n

While it has seen some use in surveying stockpiles autonomously, there had been little uptake.<\/p>\n

However, over recent years the use of this\u00a0technology at mine sites and plants has increased due to the distinct\u00a0advantages it offers compared with traditional survey methods.<\/p>\n

Point cloud data uses a 3D set of vertices\u00a0represented by X, Y and Z coordinates that is gathered via 3D laser scanners.<\/p>\n

Vast\u00a0numbers of points are collated from a given surface to produce a high point density\u00a0representation of an area or object.<\/p>\n

This becomes particularly relevant to the\u00a0mining industry in its ability to tackle vast, complex and even underground\u00a0sites with far greater simplicity and convenience than conventional surveying.<\/p>\n

Accuracy,\u00a0time, and cost efficiency are just some of the benefits laser scanning has to\u00a0offer.<\/p>\n

From a detail d\u200besign perspective<\/b>
\nPoint cloud technology, from a detail\u00a0design point of view, not only makes the job in hand that much easier, but\u00a0minimises the potential for human error to almost zero.<\/p>\n

The captured data\u00a0provides an \u2018as built\u2019 status, giving a real-time snapshot of the site as it\u00a0currently is and the subsequent data processing that follows has a fast\u00a0turnaround.<\/p>\n

This negates the risk of changes at site affecting plans, drawings\u00a0and tenders.<\/p>\n

The accuracy and coverage of the gathered\u00a0data eliminates incorrect measurements or the need to make estimations.<\/p>\n

In\u00a0conjunction with CAD technology, specific measurements can be extrapolated to\u00a0provide exact calculations.<\/p>\n

For quality assurance purposes, using the point\u00a0cloud data against prepared drawings is an excellent tool to clearly identify\u00a0incompatibilities.<\/p>\n

The data also has a multitude of other\u00a0uses, such as clash detection of existing infrastructure and determining what\u00a0aspects need to be removed, modified and in which order.<\/p>\n

New designs can be\u00a0reviewed internally and externally with client and maintenance teams, prior to\u00a0fabrication and installation to identify potential problems and amend\u00a0accordingly.<\/p>\n

Additionally, the 3D point cloud data can be scanned to suit the\u00a0plant coordinates or even a real-time satellite position.<\/p>\n

This allows the new area\u00a0being modelled to be positioned into Google Earth or any other real-time\u00a0satellite imagery, allowing site a true aerial preview of the new construction.<\/p>\n

Simplicity and \u200bconvenience<\/b>
\nThe generation of a 3D replica of a\u00a0physical object, regardless of size, layout or density can generally be\u00a0performed while the plant is in production.
\nSite personnel can continue with\u00a0site activities as their presence does not interfere with data collection.<\/p>\n

This\u00a0presents huge opportunities as the majority of the site can be surveyed during\u00a0production without the need to schedule downtime and reduce productivity.<\/p>\n

Where interior survey of, for example, a\u00a0grinding mill is concerned, a short amount of downtime is necessary.<\/p>\n

However,\u00a0by using a laser scanning service such as\u00a0MillMapper (Scanalyse, now part of Outotec), it\u2019s possible to scan mills\u00a0in as little as 15 minutes and this can be scheduled to coincide with a planned\u00a0inspection shutdown.<\/p>\n

Both MillMapper and CrusherMapper (used for gyratory\u00a0crusher analysis) use patented, proprietary software to process laser scanning\u00a0data, providing 3D files and reports on liner thickness wear and cross-sectional\u00a0\/ longitudinal profiles.<\/p>\n

Service life projections are given at the average and\u00a0fastest wearing points.<\/p>\n

Localised critical areas of breakage, cracks and uneven\u00a0wear are highlighted, resulting in significantly improved liner assessment\u00a0being provided as the total surface is mapped, not just accessible areas.<\/p>\n

In terms of safety, both internal and\u00a0external scanning reduce the need to work at heights or in confined spaces as\u00a0laser scanners can be placed strategically in vantage points for remote\u00a0scanning.<\/p>\n

While a miner may potentially expect\u00a0higher up-front costs due to production and manipulation of the data, the net\u00a0results from minimised downtime alone will offset this cost.<\/p>\n

This, coupled with\u00a0the convenience of the survey, quick procedure and turn-around, along with\u00a0clear, highly accurate and informative imagery, more than compensate over the\u00a0course of the entire project.<\/p>\n

The fabrication stage also benefits from the\u00a0inherent precision in plans and drawings which will potentially reduce\u00a0commissioning time.<\/p>\n

A complete plant can be scanned within a\u00a0day and the data files compiled into one or several 3D models and available to the\u00a0design team within a short time frame.<\/p>\n

High density imaging<\/b>
\nThe data produced from the millions of\u00a0points captured in a 3D environment is generally processed via a CAD program.<\/p>\n

These\u00a0high density CAD images offer numerous advantages including versatility.<\/p>\n

Sections\u00a0of an image can be isolated or cut and viewed from any angle in the same way as\u00a0a 3D CAD model.<\/p>\n

The extensive data also provides the same detailed information\u00a0of surrounding areas.<\/p>\n

Exact calculations of space and measurement allow construction,\u00a0access and craneage around existing infrastructure to be planned well in\u00a0advance, without the need to revisit the site.<\/p>\n

When processed, point cloud data images\u00a0provide the basis for digital manipulation, giving an accurate, impressive and\u00a0true representation of the project.<\/p>\n

Whether rendered, false or true-coloured,\u00a0the images are highly detailed.<\/p>\n

Every fine point is captured which by any other\u00a0method may have been missed, including non-documented assets such as cable\u00a0trays, service piping and on-site modifications.<\/p>\n

With so much information\u00a0readily available in the digital files, time spent sorting through and\u00a0analysing multiple drawings and site sketches is greatly reduced.<\/p>\n","protected":false},"excerpt":{"rendered":"
