Customers make use of MICROMINE software to increase the value of their assets, boost productivity, and make decisions on which they are able to be able to rely. Since its inception, 30 years ago MICROMINE solutions are utilized in more than 2,000 locations across more than 90 countries. Access to data is not always easy or quality-control issues could result in millions of dollars if incorrect modeling and decision-making results.

Miners are also able to communicate with the program in order to make day-to-day activities and production processes more efficient, quicker, and more effective. Micromine comes with a variety of modules that meet different requirements and every user can choose either one of the modules based on their specific needs.

Micromine can also work with 64-bit systems that can handle greater amounts of data and performs better. The toolbox MICROMINE provides solutions that allow you to collect, analyze and interpret crucial mining and exploration information. You can work with a variety of sites, parameters, and resources when designing and managing geological or mining exploration projects.

Micromine 2020 is a flexible and scalable solution that is scalable and flexible, Micromine 2020 provides you with the option of choosing the features you require when you require them. Furthermore, the emphasis on 64-bit technology in Micromine 2020 means that you will be able to perform faster and more effectively with more information than you have ever had before. Micromine is an all-inclusive solution for mining exploration, design, and exploitation.

These three items are inputs into an underground operations Equipment Control Plan. In this article, Micromine summarises regulatory changes and how a Mine Control System deployed alongside your Ventilation Control Plan can assist operations in regulatory compliance.

The cornerstone of any mining operation is its workforce, and their safety is non-negotiable. The Government of Western Australia Department of Mines, Industry Regulation and Safety Work Health and Safety (Mines) Regulations 2022 is a comprehensive guide that prioritises the protection of miners. These regulations ensure regulators can enforce a safe working environment and provides a framework for operators to meet legal requirements.

The guidelines outline the responsibilities of personnel who support the operations of a mine. From mine operators, addressing crucial aspects such as air quality to mandating continuous monitoring of atmospheric contaminants, monitoring devices, and record-keeping. There are so many crucial factors at play in operating a safe underground mine site balanced against potential cost savings achievable through the effective control of secondary fans.

By not complying with the Regulations and Act, businesses open high-risk vulnerabilities to the life of their staff in delayed health risks, injuries or even more severe loss of life. Other aspects of non-compliance are costly, not only in terms of legal fines and lawsuits or costs incurred due to production shutdowns or provisional improvement notices (PINs). The mining sector is inherently OPEX-intensive with any, interruption to operations leading to unrecoverable financial losses. Effective monitoring and control of secondary fan systems can lower operational cost per tonne. Savings recognised by an operation can be maintained through periods of volatile commodity prices.

Underground ventilation systems are a pivotal component of underground ventilation and climate control. Ventilation systems circulate air throughout the mine and exhaust foul air. A Mine Control System (MCS) can track HME location in near-real-time. This can be achieved through radio-based communications room a network-enabled deployment with ruggedised PCs in-cabs combined with positioning tags.

A Mine Control System can be a direct input into an Equipment Control Plan and a Ventilation Control Plan. An MCS allows for near-instantaneous reporting on the required flow rate required within each mining area. Should your operation have an MCS, alignment of mining or reporting areas to your secondary/primary fans controls will allow the reporting of ventilation requirements. A Mine Control Solution would track:

An operation has 3 pieces of heavy equipment operating within mine area No.2. Each piece of diesel equipment has an engine power rating 600 kW. In this example we are in West Australian underground mine and a factor of 0.05 will be used to calculate the required airflow as m3 per second. Therefore:

Part 2 of this blog described the preparation and information needed to create a good scan of your original map, and Part 3 outlined some of the ways to prepare and adjust the scanned image and create the best possible digital linework using vectorising software. The result of vectorising the map is a collection of raw linework representing the original map image, as shown on Figure 1 (made using WinTopo).

Import the vectorised linework into Micromine as a string file, via File Import Vector (CAD/GIS/GPS) Data. Unless you used advanced vectorising options there will generally be no attributes or elevations to worry about. If your vectoriser did create attributes, enable Import attributes before importing.

To make a rectangular selection around a slanting line, switch to the Rotate Tool (or use the middle mouse button) and drag while holding down the Z key. This will lock the rotation around the Z-axis, allowing you to swivel the view until the slanting line is aligned with the screen. Then just do a normal rectangular selection.

You make length-based selections in QGIS with the Select features using an expression button on the Attributes toolbar (or directly within the attribute table), using the inbuilt $length attribute in the Geometry group. You can then update the selected features within the attribute table.

To join individual strings into one long string in Micromine, Ctrl+click the individual strings in the order you want them joined, and then right-click Join Strings. Joining many strings will be easier in Micromine 2016 because you can just drag a rectangle around them and use the new Coalesce Strings tool to combine them. Micromine 2016 automatically figures out the joining order. We plan to release this version by the middle of next year.

Condition the strings once you finish joining and attributing them so that you avoid problems caused by coincident (or nearly so) points. To do this, select all of the strings and then right-click Condition String. At the very least you should remove duplicate points and retraced lines, but you could also experiment with setting a smallish minimum separation (equivalent to about one pixel). You may also wish to experiment with simplifying or smoothing the strings.

Although the minerals industry embraced digital technology back in the 1980s there are still many historic mines with huge (and unused) archives of paper data. Converting these paper maps into a digital, and preferably 3-D, format can be daunting but is vital for making this legacy information accessible to modern-day operations.

Georeferenced and rectified images from modern large-format scanners have all-but eliminated the need for traditional digitising tablets. Today the pain of digitising legacy data is much reduced when scanned maps are spatially rectified to remove distortion, enhanced to reduce defects and bring out important detail, and then handed to automatic vectorising software to digitally capture the linework. Digitising a large archive of paper maps is still a time-consuming process, but it has never been easier than it is today.

I am grateful to the staff of Klondike Silver Corporation for providing historic mining data from the Sandon Mining Complex and related properties in British Columbia, Canada. This workflow was initially developed using that data, and was later expanded to include contour and geological maps.

Anyone working within a historic mining area will eventually need to digitise old paper drawings and maps. With ready access to modern high-quality large-format scanners, digitising a scanned copy of a map on a computer monitor (via heads-up digitising) has essentially superseded traditional digitising tablets. Even better, you can automate much of the process for clean maps that have few or no filled areas.

Cleaning up the paper map should be done lightly with a good quality soft eraser to avoid damaging the paper. Getting rid of obvious scuffs, dirt or fingerprints now is better than cleaning up the scanned version afterwards.

You may not always get a chance to scan a map, and in this situation you can always resort to photographing it instead. For the very best results you should use a digital SLR camera mounted on a copy stand, with a high quality macro lens and remote release, and two identical lights shining at 45 from opposite sides of the map.

In the resource industry many readers will have seen whiz bang productions at conferences running on loop as juniors attempt to spruik their projects. Most of these fly throughs will have been created by one of a small number of consultancies specialising in this technology. These productions are however very costly and in the last couple of years the numbers of companies willing to pay has reduced in line with the downturn in the resource sector generally.
