There is an article in this months Cornwall Today about Crofty and the RSV they have been testing recently. I appreciate that on this subject the words granny and eggs spring to mind and the WUM web site covers it better anyway with additional info. Apologies if this is old hat news. [web link]

I've seen the quite impressive results of fixed-station laser scanning so I'll be interested to see what comes out of a mobile station system like this, and how much quicker it can work.

It is good to see what was the CSM still being able to test new ideas at Crofty, for the benefit of both.

this is really an alternative application of an existing idea, rather than a new idea as such. When you see those vans on the motorway with 'Surveying in Progress' on the side, that's what they are doing. The railways use it as well, for track alignment and condition monitoring.

that said, there must be some new content because however the robot located itself, it certainly won't be by GPS.

If the results are comparable with those achieved elsewhere, it should be good

Dead right, you can't stand still. It's all very well sitting in the Plume of Feathers moaning that "fings ain't wot they used ter be" but life moves on. Cousin Jack used to be in demand everywhere because of his state-of-the-art skills; you have to offer things people want.


I'm glad in some ways I'm not so far off retirement now, because the Mine Surveyor's job will hardly exist, 10 or 15 years from now. Mind you, I knew Peter Merrett at CSM, so I'm glad to see us old farts are still good for something... Smile

Not too far off topic, I hope: I was chatting to a friend of mine yesterday who carries out 10 - 15 meter deep surveys using a portable ground radar system, the results of which are displayed on a 3D 'map' using dedicated software. He was expecting to be down in the Camborne area this year surveying a piece of ground for the County Council who were planning to develop the land for housing/industrial estate purposes. It turns out this particular piece of land is part of the South Crofty sett and they are refusing to sell the land in question. Does this strengthen the rumours of a possible Cornish mining revival?

The results from this work are pretty impressive and makes a welcome addition to the surveying that I carry out. It was an interesting few days while the scanner etc was underground. I do hope that more can be done especially in the old workings.

There are some results on YouTube type in South Crofty into the search. Happy viewing.

I've seen this used for tunnel profile monitoring on the railway, and for detail and dimensional control in refineries and oil platforms.

We have been using laser scanning extensively at Combe Down for mapping underground voids. Some areas of the old workings have no underground access, and certain areas have been stabilised by a programme of surface drilling. The tool here is inserted via boreholes 4" or 6" in diameter and gives a sort of 'cogwheel' or 'sunburst' shape, because the pillars and fallen debris create 'shadows' which radiate from the point source; but it's still a great improvement over original information which is mostly missing altogether, and with experience of interpretation has become quite a reliable tool
