CANADIAN TECHNOLOGY through the new Newtrax IoT Hub, providing actual shift data to compare with the operating plan. All data collected can also be integrated to third- party applications for reporting and visualisation, such as MSBI via GraphQL API. Communications The success of such systems hinge off the communications backbone of a mine, an area Calgary-based 3D-P focuses on. While larger mines and those looking to automation and high levels of digitalisation are often the most obvious candidates for new LTE connectivity, 3D-P thinks a hybrid LTE solution can offer smaller mines the chance to ramp up their digitisation efforts. One of the expected benefits of LTE is connectivity at greater distances than what Wi-Fi traditionally offers. This has seen several large companies such as Agnico Eagle Mines (La Ronde), Newcrest Mining (Lihir), South32 (Cannington) and MMG (Las Bambas) ramp up their LTE efforts in recent times. Yet coupling this distance connectivity benefit with a hybrid solution like the 3D-P hybrid LTE/InstaMesh ® (from Rajant) client can offer smaller operations a simple and affordable network, according to the communications provider. This allows remote access to their data in near real time, it says. “In this scenario, with no network required at the bottom of the pit, vehicles can still remain connected and sharing data via peer-to-peer connectivity,” 3D-P says. “Leveraging the Store and Forward capabilities of the 3D-P hybrid client, data is stored on-board the client while travelling outside the pit and is communicated to the server as coverage resumes and the client connects to the LTE network either directly or through a connected peer.” With minimal infrastructure requirements, the solution is suited to applications with non-real-time communication requirements, the company said. After such a hybrid network is installed, mines need to leverage the data they receive. “The good news is that a number of simpler, more affordable applications have appeared over the last few years making digitisation an option for smaller operations,” 3D-P said. “Even better, and critical to smaller operators, is the ability that those new solutions provide to prove rapid return on investment on the technology.” SAFETY - First, Last and Always.

Permafrost-proof grout Cementitious grout for various ground support applications has been utilised by the mining industry for decades. Yet, as the limits of mining geography expand, new challenges are being encountered. In the Great Canadian North, for example, extremely low temperatures restrain the use of normal cementitious grout. Alongside the need to operate in these extreme conditions, the mining industry is also dealing with a technology evolution where new innovative equipment is being used to accelerate the mining process and reduce the risk of injuries associated with carrying out manual operations. Automatic cable bolters (see Figure 1) are the perfect example of this. This new type of equipment can be designed with an automatic batching and injection system for cementitious grout, but these high-tech bolters have been designed for normal cementitious grout; grout that does not perform in freezing conditions, according to Simon Reny, National Director Shotcrete, Tunneling & Mining for Sika Canada. “Based on known existing cementitious technology for filling structural piles in permafrost, commercially known as King Nordic grout, the Sika Canada research and development team determined the industry would need adapted versions of this grout,” Reny said. “The grout would need to be either installed automatically or manually at a fluid consistency for the EXPERIENCE • • • • Shaft Sinking Mine Development Contract Mining Raiseboring • • • • Raise Mining Underground Construction Engineering & Technical Services Specialty Services AFRICA | ASIA | AUSTRALIA EUROPE | NORTH AMERICA SOUTH AMERICA Mining Contractors and Engineers Consider it done – safely. redpathmining.com APRIL 2020 | International Mining 51
