The mining industry continues to be a hotbed of patent innovation. Activity is driven by improved computing power and connected sensors to control and monitor the mining environment. Mining companies can increase efficiency, improve productivity and safety, and reduce costs on the mine site by adding internet connectivity and sensors to vehicles, machinery, and people. Examples of this include autonomous drilling, driverless haul trucks, and predictive maintenance. In addition, it is imperative to provide workers with clean, non-toxic air and sufficient oxygen in underground mines, and IoT sensors can monitor potential dangers, such as convergence or toxicity, in real-time. In the last three years alone, there have been over 62,000 patents filed and granted in the mining industry, according to GlobalData’s report on Internet of Things in mining: tunnel safety monitoring.

Smarter leaders trust GlobalData
According to GlobalData’s Technology Foresights, which uses over 70,000 patents to analyze innovation intensity for the mining industry, there are 40+ innovation areas that will shape the future of the industry.
Tunnel safety monitoring is a key innovation area in Internet of Things
Tunnel safety monitoring helps to rescue people inside a tunnel and to maintain air quality and control spread of smoke in case of fire or a disaster. As mines become deeper, more remote, and technically more difficult, the ability to source tunnel safety devices becomes more important than ever. Global corporations are witnessing a technological revolution in the underground mining sector. Automation enables the safe and remote operation of equipment, while smart technology enables real-time performance monitoring to drive cost and productivity improvements. Devices such as drones, wearables, proximity detection sensors on moving machinery and vehicles, and scanners to identify different ore grades and feed this information through the mining value chain can all yield small but cumulative gains in productivity.
GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 270+ companies, spanning technology vendors, established mining companies, and up-and-coming start-ups engaged in the development and application of tunnel safety monitoring.
Key players in tunnel safety monitoring – a disruptive innovation in the mining industry
