Ventilation system in underground mine Sawahluwung using suction system (exhaust) air out the quantity of  35.10 m3/s, while the quantity of incoming air of 34.50 m3/s through the three holes of entry i.e. Adit Sawahluwung            + 214 of 23.00 m3/s, Adit Sawahluwung + 223 of  6.50 m3/s and head of Sapan II of 5.00 m3/s. The amount of air entering the air out there is a difference of 0.60 m3/s caused by air leaks in the duct wall Mine Fan.

Hand in hand towards post-war mines, PTBA UPO plans make preparing hole and education as a means of education for the world of education and society, then closing and pengedaman done on the area J6-J8, J7-J9,          J1-Bak Pumps LS II. The pattern of air flow enters starts from the Adit Sa.
