Abstract

The high levels of heat and humidity in ultra-deep mining raise issues regarding the occupational health and safety of miners as well as productivity. Miners could wear a cooling vest to reduce heat strain, but it would need to be properly adapted to the constraints and requirements of deep and ultra-deep mines. This article examines the first phase of a validation of a previously proposed usability matrix composed of 16 ergonomic criteria via expert elicitation (from both the academic and mining sector) and lab experiments with human participants in a controlled environment. A questionnaire was used to ask experts to prioritize the criteria and determine which of these should be combined, rejected or added. Laboratory participants were asked to execute typical mining movements to assess a number of criteria for two different cooling vests (one prototype and one commercially distributed) and complete a questionnaire containing a 6-point Likert scale for five criteria: fit, comfort, ease of movement, usability and design aesthetics. Eight experts and ten laboratory participants completed their respective questionnaires. The usability matrix was improved and structured into a mind map representing all relevant criteria and their relationships. This mind map will need to be tested further with experts and miners to ensure and complete its scientific validity.
