Premier Coal is situated in the Collie Coal Basin in the South West of Western Australia,
approximately 200km south-south-east of Perth. The mining operations are about 15km east of the town of Collie, which is situated in the jarrah forests of WA.
Premier Coal Mine produces a clean coal with low ash and sulphur content such that it does not need to be washed and requires only crushing, sizing and blending prior to use. The coal handling equipment installed at the Premier Coal Mine is very effective. The system has been designed to supply coal in a very consistent way so that there are no variations in quality.
The coal handling plant consists of a crusher, screening plant, stockpile stacker, reclaimer and delivering system for Premier’s customers, either by conveyor, rail or truck.
As part of Premier’s open cut pit monitoring, over 29 piezometers were installed in 11 locations across the area. Previously, the data was collected manually by site personnel.
Geomotion proposed the Loadsensing G6 Data Logging system to automate the collection process, including a 5-channel node at each location and a centralised gateway. The data is presented directly in Premier’s data management software.
This system fully automates the collection and presentation of piezometer readings, ensuring the data available for analysis is kept up to date at all times.
Mascot Towers is the high-profile residential building in Sydney that was evacuated in June 2019 due to serious concern about its structural integrity.
With the rapid growth of our cities and the increasing need for affordable housing, buildings similar to Mascot Towers are popping up quickly throughout Sydney and other major Australian cities.
Concerns were initially raised when significant cracking began to occur suddenly through the building’s basement foundations (see image below).
Geomotion were engaged by the remedial engineers to supply and install structural monitoring equipment on critical areas in the building's basement.
A site walkover was undertaken on the Monday morning after the evacuation, the same day Geomotion was first contacted. Sensors were installed and commenced sending live data to Geomotion Cloud, Geomotion's online data hosting platform, by the very next day.
Geomotion's precision monitoring systems can be utilised, not only after a major structural failure event, but also during construction and throughout a building's lifespan to provide critical information on a building's structural health, early warning alarms and peace of mind for all stakeholders.
Geomotion technicians carried out the installation of 4 tilt meters on critical areas on the basement slab, with four additional tilt meters set to be installed soon.
A 3G telemetry gateway was installed to enable data to be transmitted remotely – importantly removing the need to be inside the building to retrieve data.
Geomotion's data team set up the online portal on Geomotion Cloud, where data is displayed in easy to interpret plots.
Geomotion also integrated external survey data into Geomotion Cloud, offering the client a centralised platform to view all data, enabling them to make quick and informed decisions.

THE word “smart” is ubiquitous these days. If you believe the hype, smart farms will all employ sensors to report soil conditions, crop growth or the health of livestock. Smart cities will monitor the levels of pollution and noise on every street corner. And smart goods in warehouses will tell robots where to store them, and how. Getting this to work, however, requires figuring out how to get thousands of sensors to transmit data reliably across hundreds of metres. On September 15th, at a computing conference held in Miami, Shyam Gollakota and his colleagues at the University of Washington are due to unveil a gadget that can do exactly that—and with only a fraction of the power required by the best devices currently available.
Dr Gollakota’s invention uses a technology called “LoRa” (from “long range”). Like Wi-Fi, this allows computers to talk to each other with radio waves. Unlike Wi-Fi, though, LoRa is not easily blocked by walls, furniture and other obstacles. That is partly because LoRa uses lower-frequency radio waves than Wi-Fi (900MHz rather than 2.4GHz). Such waves pass through objects more easily. More importantly, LoRa devices make use of a technique called “chirp spread modulation”. That means the frequency of the carrier wave—the basic radio wave, which is then deliberately deformed in order to carry data—rises and falls in a sawtooth pattern. That makes even faint LoRa signals easy to distinguish from background noise, which fluctuates randomly.
Generating that carrier wave requires a lot of power. But modulating it, in order to impress data upon it, can be done by a chip that consumes almost no power at all. Conventional LoRa transmitters do both jobs. Dr Gollakota proposes to separate them.
In his take on the system, a central transmitter, hooked up to a big battery or to the mains, broadcasts the carrier wave, while the task of impregnating it with data is done by a chip on the sensor. It accomplishes that by choosing to earth its tiny aerial, or not, millions of times every second. When the aerial is earthed, part of the carrier wave will be absorbed. When it is not, it will be reflected. If one of those cases is deemed to stand for “1” while the other represents “0”, the chip can relay data back to a receiver with the whole process controlled by three tiny, and thus very frugal, electronic switches.
Dr Gollakota reckons that such chips can be made for less than 20 cents apiece. The signals they generate can be detected at ranges of hundreds of metres. Yet with a power consumption of just 20 millionths of a watt, a standard watch battery should keep them going a decade or more. In fact, it might be possible to power them from ambient energy: Dr Gollakota and his colleagues have experimented with running the chips from the electricity generated when light strikes a small photodiode. Like other LoRa devices, the chips are slow, transmitting data at about the speed of an old-fashioned dial-up modem. But most smart sensors will produce just a trickle of data in any case.
The researchers are keeping quiet, for the time being, about the orders they have received. But early applications could be medical. The team have incorporated the chips into contact lenses and a skin patch. In hospitals, the chips could help track everything from patient gurneys to syringes and stethoscopes. Last year, Dr Gollakota unveiled variants of the chips that use ordinary Wi-Fi, too. These, he says, are in the process of making their way into disposable drug-delivery devices that notify patients via their phones when their medication is running low. That seems like a smart start.

Geomotion recently completed the establishment of a complete remote monitoring solution for South32 at its Worsley Alumina refinery near Collie. The system draws on data from piezometers spread over 5km across the site.
Manual monitoring of piezometers across the site was a lengthy process usurping a significant amount of man hours to ensure the safety of the plant infrastructure. With the new system implemented by Geomotion Australia, data is updated daily on a web based data management platform, with the ability to increase read frequency during critical periods. It allows up to date monitoring, comparison to weather events or pumping activity on site, and offers a comprehensive yet accessible review and report functions.
The Loadsensing G6 data logging system allows up to 10 years power autonomy, yet maximum coverage across the site. With a single Gateway positioned at the site communications tower, the site is covered for monitoring of tailings dams across the facility. Maxwell Geosystem’s Mission Monitor powers the data management and reporting functions.
The project follows the successful implementation of over thirty G6 data loggers across the Illawarra Region with Geosensing Solutions on behalf of South32.
