The workings in mines of Raniganj, Jharia and other coalfields of India are gradually proceeding toward dip and are becoming more and more extensive. The conventional ventilation system mostly fails to provide good environmental condition at the workings of these mines even after replacement of main fan by higher capacity fan. Further ventilation cost is high. Multi-zonal ventilation system using large diameter borehole is a cost effective method of ventilation which can provide good environmental condition even in remote workings of any extensive mine. The method has enough inbuilt flexibility to provide adequate ventilation for enhanced target of production at any stage of operation of a mine. The paper describes the ventilation system, its application in Manderboni Colliery of Eastern Coalfields Ltd and results of ventilation measurement after implementation of the scheme. Cost of implementation of the scheme and saving in energy cost of ventilation are also stated.
