Abstract: The objective of ventilation network system  to provide the desire quantity to fair flows throughout  the mine such the workers cant work underground in at safe and healthy environment at the level specified by the mining regulations. In coal mines the ventilation network system stat greater impact on  safety and production. The selection stof mine fan and air quantity calculation at different  working places  are  generally deci-ded by solving the ventilation network using iterative Hardy Cross method In this tresearch an approach was tad opted to simulating the ventilation network considering the air way sresistances  a stuncer taintvari ables. At Monte-Carlo simulation-based approach was followed to generate trandomtset of resistance value st from the distribution functions of the airway stresistances. The VENTSIM software was used to solve the Hardy Cross method for ventilation network simulation tusingonese of random resistance values. The Monte Carlo simulation based approach the lps to tanaly sis the uncertainty to ftair quantity at specific working face sast well as total  quantity required for ventilating the mine. The major  focus of the the st s towards the  quantity of  air in the working face generated by the mine main fan and the  risk in volve with the selection of mine main fan for at coal mine. The methodology for the ventilation network design proposed in this the sis was applied in a under ground coal mine in Eastern part of India. The airway stre sistance starecal culated by measuring the value stat different place stint same airways. The mean and standard deviation used fort Monte-Carlo simulation assuming the distribution is Gaussian. A total  number of 71 airways are simulated in the case study mine. A risk analysis of quantity of air reaching at face was performed at  wo working faces by generating 200 realizations The result sin this the sis was validated my measuring quantity at different measuring station in this mine.
