the effects of Mining Machinery noise of different frequencies on the behaviour faecal corticosterone and tissue morphology of wild mice mus musculus
Applied Animal Behaviour Science, 2017Co-Authors: Karen Mancera, A Lisle, Rachel Allavena, Clive J C PhillipsAbstract:Abstract Mining noise has a wide variety of frequency spectra and is a potential source of stress for wildlife. We evaluated the effects of Mining Machinery noise on behaviour and associated physiological parameters at two isoenergetic frequency ranges: high (>2 kHz) and low (≤2 kHz), the latter being less audible to mice, our model species. Effects of these two frequency spectra on behaviour, organ morphology and faecal corticosterone of wild mice were compared with a control treatment with no extra auditory stimuli. The mice exposed to high frequency noise spent less time in their nest than those exposed to low frequency noise or those in the control treatment, and they spent more time circling, especially anticlockwise, which in conjunction with elevated faecal corticosterone levels may reflect a greater right brain hemisphere stress-related response, particularly in females. Low frequency Mining noise reduced grooming and circling, suggesting decreased physiological arousal due to mild stress. Low frequencies were also associated with increased faecal corticosterone in males compared to controls, which may be related to gender-based differences of the ear canal that affect frequency sensitivity. In conclusion, high frequency and low frequency Mining Machinery noise produced stress-related responses that may be important for the animals’ welfare and survival.

the effects of acute exposure to Mining Machinery noise on the behaviour of eastern blue tongued lizards tiliqua scincoides
Animal Welfare, 2017Co-Authors: Karen Mancera, P J Murray, A Lisle, C Dupont, F Faucheux, Clive J C PhillipsAbstract:The Mining industry is an important source of noise for wildlife, and the eastern blue-tongued (EBT) lizard (Tiliqua scincoides) is an Australian animal that may be impacted. We analysed the behaviour of nine EBT lizards during and after exposure for 5 s to one of five combinations of Mining Machinery noise frequency and amplitude (frequency 2 kHz, low [60-65 dB (A)] and high [70-75 dB (A)] amplitude, or a control treatment). Following exposure, lizards could leave the test chamber and enter an escape chamber, which led into a small hiding chamber. Chambers were monitored for 15 min after initial exposure. In the test chamber, lizards exposed to high frequency, high amplitude noise spent more time freezing, a typical stress response in reptiles, when compared with animals in all the other treatments. This was especially the case for lizards exposed to high frequency noise. In the hiding chamber, high frequency noise at high amplitudes decreased durations of head positioning to the right and downwards, suggesting a lateralised fear reaction, but decreased standing and freezing behaviours. We hypothesise that lizards have lateralised behaviour reactions to Mining noise, with high frequency, high amplitude noise being the most detrimental. Our results demonstrate that acute exposure to Mining noise had negative effects on EBT lizards' behaviour and welfare, which may suggest a threat for lizards experiencing chronic Mining noise in the wild, making the study of Mining Machinery noise in situ a research priority.

viability analysis of underground Mining Machinery using green hydrogen as a fuel
International Journal of Hydrogen Energy, 2020Co-Authors: Funez C Guerra, Lorenzo Reyesbozo, Eduardo Vyhmeister, Jaen M Caparros, Jose Luis Salazar, Alex Godoyfaundez, Carmen Clementejul, D VerasteguirayoAbstract:Abstract The processes and logistics of the Mining industry have continually undergone transformations in order to deal with rigorous regulations, economic considerations, safety and the social burden regarding environmental conditions (i.e. every sustainability pillar). In underground mines, the use of diesel-powered Machinery has been increased in the past decades. The combustion of diesel fuel produces a great quantity of pollutants (i.e. gas emissions, particulate matter, etc.). Thus, a constant ventilation is required to satisfy the regulations on health and safety of miners. One of the innovative transformations that underground Mining processes have adopted is the use of electrical Load Haul Dumps (LHDs) to reduce the in-mine emissions and the ventilation burden and to improve in-mine working conditions, among other benefits. Electric mobile LHDs could be further improved by replacing battery-based energy supplies with hydrogen fuel cells. The present work focuses on the techno-economic assessment of modifying electrical LHDs by incorporating different processes and equipment (i.e. fuel cell stacks, storage tanks, DC/DC converters). The base case considers the modification of the whole Mining fleet of diesel-based LHDs. As a result, a positive Net Present Value (for the project time span under consideration) and a payback period of 7.78 years were observed. The sensitivity analysis showed that considerable modifications of the current states of diesel price are required so that modifications are not feasible (diesel prices of 0.53 €/l). A tight electricity cost of 70 €/MWh was obtained as a breaking point (considerably safe for several industrial conditions).
