what rant?

If I post a rant, you will know it...

joking apart, there are a lot of well-meaning amateurs on a forum like this, and a rather smaller number of experienced miners of various descriptions and trades. Attitudes do tend to vary rather, and what is regarded a a 'bit of a laff' among the latter does sometimes fall a bit flat with the former.


likewise, there are some things done with all good intention by enthusiasts which make the professionally experienced cringe, but they generally take it in the spirit it's intended. Scaffold pole supports are, in my experience, highly esteemed for digs but not much in favour with HMIM. I certainly wouldn't go to HMIM with the sort of thing you can read on here about digging that tunnel, or a certain well-known members' solo activities in that sphere...


seeing as you cart an eimco, compressor, Hudson tub and track about, I wouldn't have thought three or four arch setts around 2.5m high x 3m span would be an issue. They wouldn't need to be full 'underground' spec, just enough to give the idea. Lay them down, bolt them up and drag them up with the eimco, easy. Tie-bolts to fix 'em at - say - 1m centres, and you have a free-standing structure; tie sills under the track for stability. Maybe a light cladding ( say 6x2 ) overhead to give the impression of spiling boards, bob's your uncle.

they look like this..



simple stuff, easily erected by hand, stable and self-supporting. You would need to check the dimensions, but you see the idea. My guess would be that 2.4m x 2.4m would be about right.

Sorry, that's 'cos the image is far too big to display in the available width so the forum crops it so the page doesn't break format.

If you like, upload it to your personal album, then you can use the copy and paste forum code to both display the image at a forum friendly size and link to the full size version.

Here's the photo in your personal album: [web link]

Underneath the photo is a block which includes the heading 'Display in Forum Message'. In there are two lines of code, the first to display the photo, the second to display it and link it (i.e. when clicked on) to the full size version.

All you do is copy and paste that code into a forum message and all the rest is done for you.

Code looks like this:

[flink ]Personal-Album-2965-Image-40363[ lpic]Personal-Album-2965-Image-40363[ /lpic ][ /flink]

And the end result looks like this:



(click image to open full size image in new window)

This applies to every photo in the database, personal album or mine specific album.

they are often an arched shape rather than these square ones, but these fit the available space and the shallow cover means that loadings are quite low.

anyway,you get the idea

Nice, but difficult to do in an amature re-drive. The horse head brackets in particular intrude rather in a level only 4' high.
I'll root ot a photo of a recent Staffs dig to post as comparison.
Here it is.



(click image to open full size image in new window)

Bear in mind that digs as opposed to mine operations are usualy undertaken in conditions that you'd refuse to work in, if you were being paid!
Also without the conveniance of haulage laid on.
All the steel work in the attached photo was snigged inbye some 400yds in upto waist deep water by some guys far too old for mining!!
You cut your support according to your circumstances - but that dosn't mean you compromise commonsense saftey.

Tweak: image tweaked to show linked larger version - easiest way of displaying an image is to copy and paste the code displayed under each image under the heading Display in a Forum Message - srl

well, quite so

I've done enough in 4ft x 4ft timber headings over the years ( you don't see those much any more, I'm happy to say ) to know the difference.

However the current topic is about a free-standing structure large enough for an eimco, aimed to give as much idea as possible to casual spectators, rather than a dig for enthusiasts

is there a larger copy of that photo, or any more phots anywhere? I'm always interested in details of amateur or historic temporary support.

Sorry -I got the wrong end of the stick!
Anyway there's a proper copy of the photo, if you look in my personal album.

Nice pictures of some steel square sets. We've just installed over 60m of this at 1m centres. Not too difficult to install, with the right equipment Wink

Having done some digs, I can certainly understand that HMIM would not approve of some of our handywork, the timbering that is. Steel however gets expensive and is difficult to manhandle especially in some of the places I have dug Wink

The last major dig I was involved in, we installed some 6 ft steel arches for over 65ft through a major collapse... We could have done with an emico to help shift all the rock ...Smile

I have to admit that I don't have either the time or the inclination to become involved with digging on that scale. Plus, I don't much care to put myself in the firing line as being someone who really should have known better when something goes wrong.

I've seen some very various support work in digs, ranging from delaminated slabs supported with scaffold poles end-on to some quite professional steelwork. I have to say that it's the timberwork that tends to be the worst; you use a lot of timber to do it properly, and there really aren't many blokes around who can do it well.

Here's an example of **** poor timbering for you - mine!!
I'm the daft sod on the jigger BTW.

Hmm why are my photos coming out so small when in posts?

Easiest way of displaying a photograph in the forum is to use the copy and paste code displayed under the mid-size verison of every photo on the web site.

Underneath each photograph you will see a block like this:



(click image to open full size image in new window)

Copy and paste (click and hold, drag and release the mouse button) either of the arrowed lines, then press Ctrl+C (or right click and select 'copy'), then Ctrl+V (or right click and select 'paste' when writing your forum message and the code will be inserted. The photo will then be displayed, automatically at a forum friendly sized and linked to the full size version if you chose to copy the second line of code.

Hope that helps.

All mine/quarry album photos also have a single click 'discuss in the forum' link, look in the right hand column. This allows you to paste the photo into a forum message, pre-selected in the correct geographic region if you want to ask a question or anything to do with the photo.

ttxela will be your friend now, he is always whinging at me about my 'readybrek' overalls...

I have done various sections of full-timbered 4ft x 4ft headings over the years, mostly for short pipe connections in soft wet ground, nasty job.

the most elaborate timber work I've ever been involved in was step-plate connections, pedestrian walkway connections, plus escalator and running tunnels driven over pilot tunnels on London Underground at Angel Station, Liverpool Street, Waterloo and London Bridge, very complex work. I wish I had some pics of it, although I still have some of the temporary works drawings.

the most nadgery, awkward job of that sort i was ever involved in was a pedestrian connection from the DLR to Northen Line at bank Station, very cramped and awkward

I don't do jiggers, sorry.

While we're deviating off topic - anyone been involved in reladdering shafts, with steel or timber ladders. A group I belong to have reladdered a 160ft shaft in Cornwall. Its good fun hanging from a rope whilst cutting hitches for the platforms !

Ladders are a little easier that ropework as many will probably comment and so is driving the pickup !

I think this topic may have moved away from the Eimco Rocker Shovel but I thought, as a parting shot you might like to see the other side of a 21B (not often seen). I've posted a pic. on Finedons Ironstone mine album. What were the rods, housed on the other side of the shovel, used for? One shovel also has a spare chain tucked in a pocket IP: 88.108.80.145
