The underground mine airflow is largely influenced by airways shape and roughness, which give impact existence of head loss. Reality in the field is not quaranted can be represented by resistance value found on literature (McElroy, 1935). To get the resistance value in field required the measurement of speed direct and accentual at airways in mine to be able to be calculated its(the resistance value). Research done will compare resistance value from result of measurement with resistance value at literature ( McEroy, 1935). Resistance value got from relative measurement to differ from literature (-392-97.9%) the difference estimated by condition of field that is not representation by literature, but could probably happened measurement mistake for area having low pressure and speed. Resistance value got at literature will be applied as input for making of ventilation network models in mine. Output from model wich in the form of air debit, will be compared with the result of measurement of field to see difference of model and measurement. Result from comparison between simulations with result of measurement of ventilation at intake with overall errors 4.35 % and exhaust with overall errors 0.09 %. (under maximum errors permitted equal to ±10%) but because model only limited models system ventilation network by playing just fan neglectfully condition of in field (Blower Fan) causing this model will be compared to model (model 2) which its the resistance input from measurement giving difference that is enough significant ( more than ±10 %). <br />
