1. Lazaro Trujillo, Lucero. Heat Stress in Hot Underground Mines .

Degree: 2020, University of Arizona

This dissertation is focused on the assessment and prevention of heat-related illnesses in mineworkers due to excessive exposure to heat and humidity in hot environments. Heat stress is a serious environmental and occupational hazard. The damaging effects of heat stress can lead to major injuries such heat stroke, heat exhaustion, or even death. Recent trends indicate no progress towards decreasing the heat-related accidents in the mining industry as reported by the U.S. Mine Safety and Health Administration, despite unquestionable advances in the area of mine safety in the last twenty years. Adherence to standardized heat indices that are appropriate in mining work-site environments is decidedly beneficial. The purpose of the study was to: i) review of the current state of knowledge about heat stress and strain from published and specialized literature; ii) validate the Predicted Heat Strain (PHS) [ISO 7933 (2004)] model, one of the most scientifically robust index, through a comparison of the predicted core temperatures by the PHS model with a direct physiological measurement obtained from an ingestible telemetry pill (VitalSense capsule), and iii) improve the performance and accuracy of the PHS model by developing a new expression that relates core body temperature as a function of stored heat and skin temperature. Primary sources of data for the current study, including environmental and real-time physiological data, were collected from ten subjects performing typical mining activities at two underground mines located in Arizona.
