Mine Scanning

Post by schwoeps »

Had an interesting call yesterday, client was wondering if it would be possible to scan the interior of a coal mine. The purpose of scanning would be to see what remains of the structural members inside the chambers. The interesting part is the mine is closed off and 160+ feet under the surface of a mountain. The only access would be from bore holes they would drill into the chambers. The hole would only be about 8" - 10" dia. If this is possible a scanner would need to be attached the rig an lowered into the chamber. I am not aware of any scanner that would be small enough to fit into the bore so I thought I post here to see if any of the experts here have any ideas. We are not sure to the extent the point cloud would be used for (pulling dimensions, sections etc.) If the cloud is not needed for anyhting, we were thinking that a video camera system would probably be best for a visual inspection. Also there would be other issues with scanning that may not lend itself to this type of enviroment. Fire away with an ideas if you have any.

Thanks,
Schwoeps

Hi schwoeps,

the Optech CMS would perfectly fit to your specifications.
Scanner head is approx. 17 X 15 cm (I think 8" to 10" must be 20-25 cm), so should be perfectly passing the bore hole.
If you need any more information drop me a pm.

If resolution wasn't important you could use a total station with plane scanning capabilities (like a Trimble S6 or higher, for example). That would give you a reasonable mesh for dimensions, etc, although I dont know what the response would be like for any instrument from a black coal face...

You would have to have light to use a standard video camera. Perhaps a small IR security camera would work.

I think to use a scanner, you would have to build some sort of rig that would hold and protect the unit on the way down, and stablize it during the scan.

Sounds like an interesting nut to crack.

We had a similar request yesterday in that a very small unit is needed to fit into a pressure vessel in a glass plant. Our HD6000 will fit in a 15" hole, which is too big. What is the smallest scanner out there built tough enough for industrial use?

Worth a look, though I suspect it might be a little too big.

This might be better for you...?
