temperatures approaching 60°C and chamber temperatures commonly at 40°C with high humidity. Thus, even_x000D_
moderate physical work can cause miners to quickly exceed existing occupational heat exposure guidelines and_x000D_
increase risk of heat illness. An extra risk is the prolonged transport to surface medical facilities. Beyond health_x000D_
and safety concerns, productivity is reduced due to an inefficient work-rest regime. Further, the achievable ore_x000D_
depths are limited by cautious heat stress management._x000D_
Currently, the primary strategy for reducing thermal stress in ultra-deep mining is by cooling and ventilating_x000D_
mine chambers, with the penalty of very high energy requirements and costs. A potential alternative for_x000D_
occupational cooling are individual personal cooling systems, where cooling is customized to the individual._x000D_
Beyond improving worker health, this approach has the economic benefit of large energy savings through_x000D_
reducing the need for wholesale cooling of large mining chambers._x000D_
Jannatec Technologies, based in Sudbury ON, is developing a portable Active Cooling Vest to decrease the risk_x000D_
of heat stress for miners working at ultra-deep depths, with cooling intensity individualized based on a_x000D_
combination of environmental conditions, activity levels, and physiological feedback. The present proposal_x000D_
supports this target through developing a Heat Strain Estimator Algorithm (HSEA) to regulate the cooling of_x000D_
this Active Cooling Vest. This will be accomplished by: 1) developing a model to predict core temperature_x000D_
from heart rate and skin temperature; 2) developing the HSEA to predict overall heat production during_x000D_
different mining tasks; 3) Incorporate and test the HSEA's ability to serve as a health warning system and to_x000D_
control a personal cooling system to reduce heat strain in the lab and during actual mining. The overall goal is_x000D_
to greatly reduce heat strain and increase productivity in ultra-deep mining., program purpose french : One occupation featuring continuous high levels of heat stress is ultra-deep mining, with the rock face at_x000D_
