The mining industry has traditionally relied on manual labour-intensive processes for extracting minerals and other natural resources from the earth. However, in recent years, mining companies have started adopting new advanced technologies such as AI, automation, IoT, big data analytics and robotics to transform mining operations. These smart technologies are helping mining companies improve safety, productivity and reduce operational costs.
Use of Automation and Robotics
One of the major areas where mining companies are applying new technologies is automation and robotics. Underground mining operations have historically been challenging and dangerous for human workers. To address safety concerns, mining equipment manufacturer such as Caterpillar, Komatsu and Hitachi have developed autonomous trucks and loaders which can operate safely underground without human intervention. These driverless vehicles use technologies like advanced sensors, GPS and tele-remote operations to navigate the mine site and transport materials. Mining companies such as Rio Tinto have already deployed fleets of autonomous trucks and equipment at their sites achieving significant increase in productivity and reducing accidents. Robotic drills, dozers and other machinery are also being used to automate difficult and hazardous surface mining tasks.
Remote Operation and Monitoring
Advancements in connectivity and internet of things (IoT) have enabled remote operation and monitoring of Smart Mining equipment from anywhere. This is another key area where technology is helping improve safety of mining workers. Mining machines are being embedded with various sensors to collect operational data which is then transmitted using wireless networks to remote operation centres. Skilled operators can safely tele-operate heavy machinery parked underground using controls, camera feeds and analytics displayed on consoles located above the ground. Remote operation allows miners to avoid hazardous areas and situations altogether. Mining companies are also using IoT sensors to continuously monitor equipment health, working conditions and optimize maintenance schedules.
Big Data and Analytics
Mining generates huge volumes of operational data on a daily basis from sensors, equipment, geology reports which was previously underutilized. Big data analytics helps companies gain meaningful insights by processing and analyzing this disparate data. Analytics tools are used to detect patterns, efficiencies and anomalies in historical production and maintenance records. It helps predict equipment failures, optimize extraction plans, grade controls in real-time and discover new ores and minerals. For example, Rio Tinto's analytical models detect small variations in iron ore composition online which enables them to automatically blend ores during extraction for higher recovery and product quality. Big data is revolutionizing decision making across all aspects of mining from exploration to logistics.
Artificial Intelligence Applications
Advancements in machine learning and artificial intelligence (AI) are also being leveraged by mining companies. AI assists in automating tasks like geophysical modeling, drillhole targeting, reserves estimation during exploration phase by processing vast volumes of geoscience data. Computer vision combined with AI helps automate ore sorting on conveyor belts to separate waste rocks and optimize processes. Real-time prediction of rock conditions underground using AI helps robots and autonomous equipment plan safe paths of movement. Predictive maintenance models based on deep learning techniques analyze equipment performance data to predict component failures in advance. Mining companies are also exploring uses of AI in resource scheduling, logistics optimization and remote personnel safety monitoring. Overall AI will continue to augment human decision making capacities across mining value chain.
Increased Efficiency of Operations
Implementation of smart technologies has significantly improved operational efficiency of mining companies. Automation has increased productivity of mining fleets by reducing equipment downtime and improving equipment to operator ratio. For example, autonomous trucks at Rio Tinto's mines in Australia operate 24/7 achieving a 90% increase in haulage productivity compared to human operated trucks. Remote operation improves safety of workers by removing them from hazardous underground environments. Big data analytics enables real-time optimizations and decision making while reducing unplanned downtime. AI assists human workers by automating complex decision processes. The result is higher resource recovery rates, consistent quality of production and reduced operating costs per tonne. Smart mining will help achieve the targets of “zero harm”, improve business resilience and sustainability in long run.
Challenges of Transition
However, transitioning to smart mining is not without challenges. There are technological, organizational and cultural barriers that mining companies face. Building connectivity infrastructure in remote mine sites for IoT is a major hurdle. Ensuring cyber security of networked equipment is another concern area. Lack of data standards makes it difficult to integrate disparate systems across mines and sharing information. Workforce up-skilling and changing existing processes to leverage new technologies requires significant change management efforts. Transitioning from traditional safety culture to remote operations also needs careful planning. High upfront capital costs and long payback periods act as a deterrent for many companies considering new technologies. Sustained investments in R&D along with partnerships are necessary to address challenges and rapidly commercialize innovation in mining sector.
Overall, smart mining represents the future of mining industry globally. As technology costs continue declining and its benefits become evident - adoption rates will only accelerate. By 2025, 40-50% of mining work globally is estimated to be automated. Underground mining operations are expected to be fully autonomous without any human intervention in future. Drones, AI, robots will completely transform exploration, development and production phases. Big data capabilities will advance to new levels with distributed ledger technologies. Remote centers of excellence will emerge to remotely manage entire mine sites using advanced digital systems. New technologies will address sustainability challenges by reducing environmental footprints of operations. Smart mining will drive step improvements in safety, productivity and efficiencies to ensure competitiveness of mining sector in long run. With continued innovation, mining industry is poised for major transformation through adoption of new technologies.
