Hello robbo24 That small drive was blocked off and was behind the compressor .
The pipes in the grass are the air and water pipes that rang all the way along the 8 level.
Those small drives did all meet up that's why there is air coming out .
There is a small drive that comes out on the left hand side of the valley which draws a lot of the air .You have to walk about half way down the 8 level then turn left and walk out to the entrance of the drive though a stope ,that's the only way you will find the entrance .
