| Summary: | Tracer gas method has known as method that can be used to define leakage and
location on mining ventilation net system and air distribution from the intake to the outlet
(Hardcastle et al.,1992; Sasaki, 2002; Widodo, 2006) . The method that can be used in
this is pulse injection that is Tracer gas liberated on certain volume and time at the intake
and then measure the concentration of time continuosly at the outlet. The result of
concentration measurement then analysed with the macthing process using Taylor
Solution (1954) wich have been modified by Sasaki and Dindiwe (2002). In calculating
with numeric solution, the parameter that has to calculate is c (x,t), concentration at
certain place and certain time. The value of airways cross section (A), length (L) and
time (t) has been given and known, while the parameters that must changed are air
velocity (u), debit (Q) and diffusion coefficient (E). Calcullating with numeric solution
will be result concentration curve.
