TL;DR: In this paper, the optimal crowd arm and hoist rope speeds for given initial conditions, material properties and uncertain bulk densities were found to be 0.1795 and 0.2428 kJ-s/kg.

TL;DR: In this paper, an intelligent shovel excavation (ISE) technology with real-time formation identification, recording, and knowledge transmission capabilities is proposed to solve the variability of material diggability, resulting in varying mechanical energy input and stress loading.

TL;DR: Estimation of dietary intake of pesticides from fruit and vegetables revealed that, pesticides detected in fruits and vegetables did not cause dietary intake risks, and the need for regular monitoring for pesticide residues of a greater number of samples for long periods, especially in fruit and vegetable, to protect consumers’ health is recommended.

TL;DR: This study was an attempt to review and analyze all the recent automation related work in every sector of the mining industry including mineral prospecting and exploration, mine planning, equipment selection, underground and surface equipment operation, drilling and blasting, mineral processing, etc., for establishing the existing frontiers of technological advancement.

TL;DR: In this article, a stochastic simulation framework for the selection and sizing of a truck-shovel system in open pit mines is presented. But the authors do not consider the impact of the size and geometry of the equipment on the performance of the system.
