Sustaining Decarbonisation: Energy Storage, Green Extractivism, and the Future of Mining
Abstract Within the context of the so‐called green energy transition, the mining industry has successfully repositioned itself as a facilitator of, rather than an impediment to, a sustainable future. Underlying the success of this claim is a discourse of sustainability that, on the one hand, equates sustainability with decarbonisation and, on the other

‘MORTAL FEAST’: Cannibal Capitalism Meets Covid‐19 in the Urban Peruvian Amazon
Abstract This article presents a surrealist urban political ecology of cannibal capitalism in the zoonotic city. It does so through an account of the first wave of the coronavirus pandemic in Iquitos, in the Peruvian Amazon, which was the worst‐hit city in the world during this initial wave. Iquitos embodies multiple dimensions of zoonotic urbanization

Regenerative Braking Energy Recovery From a Platoon Powered by a DC Electric Road System
Electric road systems (ERSs) are anticipated to be major energy consumers. The energy efficiency of an ERS can be significantly improved by implementing the practice of driving electric vehicles (EVs) in closely spaced platoons. This driving configuration effectively reduces the drag coefficient of all vehicles within the platoon, resulting in a ...

A Two‐Stage Energy‐Efficiency Optimization Approach for Conflict‐Free Dispatching in Open‐Pit Mines
A novel two‐stage dispatching algorithm is proposed for autonomous open‐pit mines that eliminates traffic conflicts, resulting in maximum energy efficiency and productivity. The fleet conflict‐free dispatching stage (online model) proposed in this paper not only allows conflict‐free scheduling of the fleet at the beginning of the shift but also allows ...

Simulation Optimization of Shovel‐Truck System in Open‐Pit Mines Considering Rockmass Parameters
The shovel‐truck system remains a popular method for overburden removal and mineral excavation in open‐pit mines, needing rigorous logistical management to achieve required productivity levels and maximize resource utilization. Fixed truck assignment (FTA) models represent a prevalent method for truck allocation in open‐pit mining, owing to their ...
