Abstract: This paper uses patent citation networks to study technological change in the mining industry between 1970 and 2015. The analysis is undertaken at both the aggregate level by jointly considering all mining-related technological fields, and at the micro-level of patents in nine sub-fields, representing specific technological “sub-trajectories”.
