| Description |
Between the fan and the face in a mine a lot of air is lost through leakage at stoppings, doors, air-crossings etc. so that a much larger quantity of air has to be circulated by the fan in order that the stipulated quantity of air reaches the face. In the present work we have developed a mathematical procedure and applied to determine average resistance of a stopping in a row. To affect the necessary iterative calculations, a computer program STOPLEAK was developed and used for analysing stopping leakages. Air leakage through doors and air crossing was also measured by conventional method in three mines viz. Moira (Jambad and Kajora seams) Sodepur (Dishergerh seam) and Kuardi 11/12 pits (Niga seam) colleries.
