0,2 Brattice cloth made mainly from jute fabrics is used in largo quantities in mines, for the purpose of coursing air around the underground working faces.
As a precaution against fire in the mines, it is essential that only fire-resistant brattice cloth should be used. This standard was originally published in mines, large or deep underground mines, or mines with multipart local exhaust systems.

The Mather Mine disaster ranks as the seventh worst mining disaster in U.S. history and the second worst in Pennsylvania on: Mather, Pennsylvania. Abstract. This Bureau of Mines handbook presents guidelines for controlling dust in underground room-and-pillar coal mines.
The dust-control techniques represented are primarily directed toward cost-effectiveness for the operators of small mines facing tightened Federal regulations due to excessive respirable quartz dust. Transformable Stopping: To make this stopping, damage-resistant brattice is converted to a permanent stopping.
After the brattice is hung, frames of 6-inch channel iron, feet wide, are fabricated on the ground, and one side is covered with gage chain link fencing.

Good ventilation is extremely important in underground mines. A well designed ventilation system can be used to control the temperature, quality of breathable air and in modern mines disperse radon gas. Air doors were used to prevent the passage of air through a mine working, in locations where access to the sealed area is still needed.
Egan, Margaret R. Bureau of Mines. In an underground mine fire, a toxic mixture of combustion product gases and particulate matter is transported by the ventilating system endangering everyone downstream.
To determine the magnitude of the problem that these toxic combustion products p Egan, Margaret R. Bureau of by: 2.

Brattice cloth and ventilation tubing used in underground coal mines and underground gassy metal-nonmetal mines is required by MSHA regulations to be flame resistant.
The test (SSFT) to determine the flame resistance is specified in 30 CFR, Part 7, Subpart B ( ).Author: H C Verakis. The last bodies, making a total of 91 victims, were removed from the mine at a.m. on May Sunshine mine officials onprovided Bureau officials with an updated accounting of mine personnel caught up in the disaster.
