Mining has traditionally been cautious in its approach to technology adoption. Operational environments are complex, sites are often located in remote geographies, and any disruption to production can have significant cost implications. As a result, digital transformation in the sector has largely progressed in phases, with companies prioritising technologies that demonstrate clear operational and business value. However, this approach is now beginning to shift as mining operators increasingly look at connectivity-led digital systems to improve efficiency, safety and operational visibility across sites. In this context, private 4G and 5G networks are emerging as a critical enabler for connected mining operations. These networks are enabling a range of applications. As mining companies increasingly look to modernise operations, Sanjit Priyadarshi, Head, Digital & IT, Mines & Minerals · Hindalco Industries Limited, discuss how connectivity-led digital transformation is reshaping their organisations, the key implementation challenges and their priorities for the future…
What are the most impactful digital or connectivity-driven use cases you are currently deploying or exploring? What measurable benefits have you seen so far?
At Hindalco Mining, we are focusing on building a connectivity-led digital ecosystem across our operations. Private 4G/5G networks will form the backbone, enabling reliable connectivity even in difficult pit conditions. This will help us scale key use cases such as the integrated command and control centre (ICCC), which will give real-time visibility of production, equipment and safety. It will improve decision-making and coordination across teams. We are deploying fleet management systems (FMSs) to track equipment, monitor cycle times and optimise fuel usage. This will help improve utilisation and reduce idle time. On the supply chain side, the bauxite supply chain tracking system and coal supply chain tracking system provide end-to-end visibility of material movement. This helps improve planning and reduce manual reconciliation issues. We are also deploying CCTV analytics for safety and operational monitoring. It will help detect unsafe practices and improve compliance. In addition, automation initiatives such as weighbridge digitalisation have reduced manual effort and errors.
What are the key use cases for private 4G/5G networks in metals and mining operations?
In metals and mining, private 4G/5G networks are quietly becoming the backbone for connected operations, especially in remote and tough terrains where traditional networks just do not hold up. Their biggest value, in my view, is simply providing reliable, low-latency connectivity right across the mine pit. That, by itself, unlocks a lot. It allows real-time data to move seamlessly from equipment, sensors and field teams into systems such as the command and control centre, which makes a big difference in day-to-day visibility and decision-making on the ground. At the operational level, these networks are critical for running FMSs effectively. You get continuous tracking of heavy earth moving machinery, better visibility into cycle times and more control over despatch. It helps teams respond quickly rather than rely on delayed reports. Another area where connectivity really shows its value is video and CCTV analytics. These use cases need stable bandwidth, and once that is in place, they become very powerful for monitoring both safety and operations in near-real time. Private networks also make it practical to scale IoT-based use cases such as equipment health monitoring, fuel tracking and environmental sensors. On top of that, they enable digital safety solutions, incidents like collision avoidance, fatigue monitoring and smart wearables, which are becoming increasingly important in mining environments.
With increased connectivity, how are you addressing cybersecurity risks in operational environments that were traditionally isolated?
With increased connectivity in mining, cybersecurity has naturally become a key focus area for us. Traditionally, operational technology (OT) systems were isolated, but now with integration and real-time data flow, the approach has to be much more structured. One of the first steps is using private 4G/5G networks with built-in security features such as SIM-based authentication and network-level encryption. This ensures only authorised devices access the network. We also follow a segmented network approach, where IT and OT systems are integrated, but still logically separated. This reduces the risk of any single breach impacting the entire operation. At the system level, platforms such as the ICCC are designed with strong data protection and access controls, ensuring data integrity and controlled user access. Another important area is continuous monitoring. With connected systems such as CCTV analytics and FMSs, we are also improving our ability to detect anomalies early and respond faster.
What are the other key challenges that are slowing down digital transformation in the mining sector? What needs to change to accelerate adoption?
Digital transformation in mining is moving forward, but there are a few real challenges on the ground. One of the biggest issues is connectivity itself. Many mines are in remote areas where network infrastructure is weak or unreliable. This makes it difficult to deploy and sustain digital systems. Another challenge is the gap in digital skills and mindset. Technology adoption is not just about systems, but it requires people on the ground to be comfortable using them and trusting the data.
There are also integration challenges. Mining operations involve multiple systems, legacy processes and external partners Bringing everything together in a seamless way is not always easy. Cost and scale play a role as well. Many solutions work well in pilots, but scaling them across multiple mines with different conditions needs careful planning.
To accelerate adoption, a few things are important. First, strong connectivity infrastructure as a foundation. Second, continuous training and change management to build a digital-first culture. And third, a clear focus on use cases that show business value early, so that confidence builds across the organisation. Over time, this combination can help digital initiatives move from pilots to full-scale adoption.
How do you expect advanced connectivity technologies to reshape mining operations over the next three to five years in terms of efficiency, sustainability and safety?
Looking ahead, advanced connectivity will fundamentally change how mining operates over the next few years. The shift, in my view, will be towards more real-time, automated and data-driven operations. With stronger networks, systems such as ICCC will evolve further. They will not just monitor but also enable faster, predictive decision-making across the value chain. We will see greater use of AI and digital twins, especially for mine planning and equipment health. This will help reduce downtime and improve resource utilisation.
On the efficiency side, connected systems will improve coordination between equipment, despatch and the supply chain. That should bring down delays and optimise productivity. From a safety perspective, technologies such as fatigue monitoring, video analytics and wearables will become more proactive. So, instead of reacting to incidents, teams can prevent them early. Sustainability will also benefit. IoT-based monitoring of water, energy and emissions will help ensure better compliance and responsible mining practices. Over time, we will also move towards semi-autonomous or autonomous operations, especially in haulage and drilling.
