Electrically operated compressor in Tunelling.

[zonal]

Did anyone have experience with using Electrically operated Compressor especially in Tunelling works? The tunnel size is approximately 1.8m x 2 m of length approx 1 km.

If so, please do provide me the Make and ratings of the machine.

I need the rating to estimate construction power requirement.

your question is a bit vague. Do you need the compresed air to power pneumatic drills . If so jumbo or hand held. If you just need air for pumps etc ,, how much water intake or are you driving the tunnel with the entire workls being presssurized??
