Preface
The main mechanical ventilator for underground coal mines is one of the most expensive items governing the productivity, safety and profitability of a mine. It requires the most tactical and strategic planning as it affects the capital and revenue expenditure of the mine for its whole life. To select a main mechanical ventilator, optimally ensuring lowest overall cost for the whole life of a mine needs elaborate, scientific and techno-commercial considerations. The ventilation requirement of any underground mine is not a static quantity, but rather it changes dynamically. In a modern mechanized coal mine, the ranges of ventilation requirements are wide and selection of main mechanical ventilators is a complex techno-economic decision. Many times, the selection of the operating point is carried out manually at the intersection point of the mine characteristics curve and fan characteristics curve, which is qualitati
