However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.
Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

According to GlobalData’s Technology Foresights, which plots the S-curve for the mining industry using innovation intensity models built on over 70,000 patents, there are 40+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, tunnel ventilation systems, mine drainage systems, and tunnel lining construction are disruptive technologies that are in the early stages of application and should be tracked closely. Battery metal recycling, precision milling and virtual industrial monitoring are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are high performance drill bits and hybrid industrial vehicles, which are now well established in the industry.
Innovation S-curve for the mining industry
Tunnel lining construction is a key innovation area in mining
Tunnel lining construction in mining refers to the process of building protective structures within underground tunnels and excavations to ensure their stability and safety. These linings serve as a barrier between the tunnel walls and the surrounding rock or soil, providing support and preventing collapses or other forms of instability. Tunnel lining construction is a critical component of mining operations, as it helps maintain the structural integrity of underground passages. The choice of lining method depends on factors such as the geological conditions, tunnel dimensions, and the specific objectives of the mining project.
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 200+ companies, spanning technology vendors, established mining companies, and up-and-coming start-ups engaged in the development and application of tunnel lining construction.
Key players in tunnel lining construction – a disruptive innovation in the mining industry
‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
