Abstract
The Bureau of Mines has developed a procedure called the brattice window method (bwm) for measuring leakage through permanent mine stoppings. In this method, a temporary fabric stopping is erected in the same entry as the leaking permanent stopping. Two windows or openings are cut into this temporary test stopping. The volumes of air passing through these windows are measured and used in an equation to find the total volume of air leaking through the permanent stopping. Comparison of air volumes measured by the brattice window method with known air volumes passing through simulated permanent stoppings in a full-scale model and in an underground mine shows that the brattice window method is an accurate procedure for measuring mine stopping leakage.
