at temperatures below 70°F (21°C); highest accident rates are connected with temperatures above 80°F (27°C). When humidity is a factor, heat stress can occur at lower temperatures. (See Appendix B Temperature-Humidity Index) How does the human body cope with heat? As warm-blooded beings, we function normally in

Each mine will, in general, have a different mine strata composition, initial mine air temperature, initial mine strata surface temperature and initial mine strata temperature at depth, and each of …

Thermal comfort increases its importance with the deepening of underground coal mines today, depending on the temperature change. It is known that the climate change caused by this factor has a ...

The ability to regulate core body temperature is a critical factor in avoiding occupational heart stress in demanding environments. Heat-related illness in an occupational setting is complex and multifactorial and includes environment (intrinsic and extrinsic), the occupational clothing requirements and physiological factors. Much of this research began in …

Adoption of this technology can control the temperature and relative humidity of air in underground mines . The heat extracted from inrushing mine water is utilized for shower …

Humidity on work performance'' in Fig. 1 [4] shows the relative humidity changes corresponding to wet-bulb tem-perature. It shows how much more temperature one will feel in high humidity corresponding to the actual WBT he is in. In mine no. 2, for instance, the WBT in LVC of both the MPPs was over 31 C, with a relative humidity of 88%.

Based on the dust concentration data and meteorological environment data monitored at the open-pit mine site, the characteristics of dust concentration and the influence of temperature, humidity ...

Coalspur is pursuing two expansions to the existing mine. One would expand the current open-pit mine to increase coal production capacity by 4.5 million tonnes per year. The second proposed expansion is for a small underground mine in the same area to test whether the company could add a larger underground mine to its operations. The IAAC ...

This study focuses on the most important factors affecting the frost formation process, i.e. the surrounding air temperature, humidity and velocity, and the surface temperature.

As the world grapples with the effects of climate change, Mines researchers are finding ways to mitigate or reverse them. Environmental sustainability is part of everything we do – from projects that focus on cleaning our water, soil, and air to research that drives cleaner energy production, resource extraction, and manufacturing practices.

In underground mines, there are many heat sources that cause the increase of temperature and humidity of air during its travel through mine airways and production workings. The mines' intake air temperature gradually increases as a function of depth, the level of mechanization, and the length the air travels through the underground openings.

Heat and humidity buildup withn refuge alternatives (RAs) may expose occupants to physiological hazards such as heat stress. The Mine Safety and Health Administration (MSHA) regulations require RAs in underground coal mines to provide a life-sustaining environment for miners trapped underground when escape is impossible. RAs are required to sustain life for 96 …

The research studied the influences of high temperature, high pressure, high humidity, noise and other harmful factors in mining conditions on the people health and safety, and investigated the ...

For eight years a Chinese mining company has been vastly expanding inside an endangered World Heritage Site, ... part of the the Congo Basin rainforest — the world's second-biggest — and a vital carbon sink that helps mitigate climate change. It also has vast mineral wealth such as gold and diamonds. Mining is prohibited in protected ...

In some deep mines, the air temperature in the workface may exceed 26 °C. In high temperature mines the air temperature reaches 35 ℃, and the relative humidity often exceeds 85% [2, 4].

The psychrometric conditions of mine air have a great effect on the health, safety and productivity of employees. When considering the climatic conditions of a mine, the high temperature and humidity problem must be considered. Thus, it is possible to find out the heat and moisture content of air by making psychrometric calculations.

As the depth of underground resource extraction continues to extend, the operating conditions in deep mines are becoming increasingly harsh, and high temperatures and …
