MIMOSA'S Mine 6 started its operations in 1969 with the name of Mine 1 and in 1997, when the operations of an old area finished, the name of the mine was changed to Mine 6. The methane concentration in the new area of the mine goes from 8 to 10 m~3/ton. In the coal seam. The main fan since 1997 has been a JOY M-96-65 with a 900 horsepower and 900 rpm electric motor. The total air volume from 1997 to June 2002 was an average of 90m~3/sec with a pressure of 2.7Kpa and a methane generation of 0.300m~3/sec. Because a high methane generation was expected, a ventilation project was designed to bring a safe environment to the coal miners and to the mine. Besides this, a methane drainage program was started in 2004. This paper will explain all the activities performed to accomplish the project with success.
