Underground Mine Ventilation Survey

Sethi, Alok Ranjan (2015) Underground Mine Ventilation Survey. BTech thesis.



Underground coal mine ventilation systems are particularly complex because of multiple seam working methods which splits the underground air network into different districts or/and panels thereby allowing multiple ventilation methods. In order to gain an understanding of the complex networks incorporated in the system, a coal mine ventilation survey is required. The information obtained from this survey is used to determine the most efficient techniques to accomplish any proposed improvements. The proper operation of the ventilation system at maximum efficiency is essential for providing a safe and healthy underground working environment. These systems should be designed to ensure that adequate amounts of ventilating and numerous split air reach each working area. Most underground coal mines in India employ an exhaust (i.e. negative pressure) ventilation system. This project deals with the pressure and air quantity survey of an underground coal mine ventilation system at Nandira colliery, Talcher. The survey work has been carried out with the help of latest instruments at nearly forty stations. Methodology of the ventilation survey and simulation of survey readings in VENTSIM has been demonstrated. Based on the simulation result, analysis was done
