 · Air curtains are produced by thin vertical planar air jets and are used to prevent exchange flows between two fluids with a horizontal density gradient. They have been shown to work effectively provided the deflection modulus (DM) is greater than a critical value (DM = 0.14). Herein, results are presented from an experimental and modeling study of the initial transient development of the ...

1-Introduction : OSH Answers

 · Ventilation is the mechanical system in a building that brings in "fresh" outdoor air and removes the "contaminated" indoor air. In a workplace, ventilation is used to control exposure to airborne contaminants. It is commonly used to remove contaminants such as fumes, dusts, and vapours, in order to provide a healthy and safe working environment.

Heat Treatment and Ventilation Optimization in a Deep Mine

In order to address the issue of high temperatures and thermal damages in deep mines, the factors causing downhole heat damage at high temperatures were analyzed, the mine ventilation system was optimized and rebuilt, and a cooling system was established. The proposed cooling system uses mine water as the cooling source, and its features are based on the analysis of traditional cooling systems ...

Room and Pillar Mining

Pramod Thakur Ph.D., in Advanced Mine Ventilation, 2019. 21.3.4.1 Self-Inertization. In room and pillar mining, pillar extraction can be so designed that mined out area is submerged in water.This provides excellent inertization but is possible only in highly inclined coal seams. Most commonly, self-inertization is provided by the methane gas released from coal seams in the gas emission space.

Ventilation air heating

If the mine experienced this calculated daily fuel cost of $11,880 for an entire year, the yearly fuel cost would be over $4 million. This is a substantial amount, and would likely make up a large portion of their ventilation operating costs. In Northern Canada, air heating costs can make up over 50% of a mine''s total ventilation costs. As such ...
