I like Tunnels (by )

After visiting the extremely cute alpacas we headed off to the Honister Slate Mine on route Simon - Al's step brother asked me what the landscape was. I confessed I didn't actually know anything about the region but I looked at the scenes passing my window and guessed at volcanic with glacial action afterwards.

My back was in a bit of a state still and I bascially could not rotated my head but I really wanted to go in - I am from the Royal School of Mines, I am from Welsh minning stock how could I not go in? This question arose when buying the tickets as Lionel has injured his foot and was using his crutch and had sandles on.

A discuession with the lady on the desk about exactly what the mine was like had Lionel not going but me more determined to go. Jean unfortunatly was wearing sandles so would have to be carried for sections of it but would be ok as long as she was ok with the dark - we were more concerned that we wouldn't be able to keep the hard hat on her!

I have been known to go into mines on crutches - I really can not resist them!

We had to wait for our guide for a while so looked around the shop - I was I have to say impressed. They had been really ingenious with the products they where making from the mined stone - not all of it slate. I thought it all looked a bit odd though and there was definatly some interesting stuff going on in the rocks. It didn't quiet look right as slate to me and there was some interesting flow and flame structures in some of the non-slate. It is lovely stone and if I ever have enough money to do things properlly in the house I shall be getting the stone from that mine.

There is a lovely bluey/green quality to a lot of it.

The dude arrived and gave us our hard hats and battery packs which reminded me so poniantly of going caving I almost backed out but then realise what the problem was.

Jeany initial struggled over the hat until she saw that we were all wearing them - she didn't have a heavey battery pack as she had basically an LED head torch. To my suprise she noticed this - 'I have blue light, special light, you have yellow!'

We clambered into an orange landrover thing and trundled up to the mine.

Outside the entrance we stared at the landscape and low! It had once been a sea flow with volcanics going on on it and then been uplifted etc... and then had glacia's move through it all carving the characteristic u-shaped vallies - these give you a nice cross section through the formation - so in staring across the valley we basically had a mirror image of what we were standing on - this was cool and gave us a much better over veiw than was could have hoped to gain any other way.

I was just a bit chuffed that my guess had been right.

We could see the layering of the ancient lava flows and slate - the slate higher up was the greener colour. Slate normally occurs from say eustry mud which becomes mudstone - this is then folded due to tectonic action and the pressure causes changes so that you get an alinement of say mica along the fold axis - this is the cleavage and is what the slate is split down. This slate looked so odd to me becuase it was not made from mud - instead it was origonally volcanic ash!

This also means that it has more griss - this is the amount of sort of large fragments in it that stop it having a smooth break down the cleavage - therefore this slate breaks into thicker slabs compared to other slates ie welsh or scottish slates. But it also means it is stronger!

The guide dude was called Fred and he was the father-in-law of the guy who set the business up - again I was really impressed as the guy had bought the mine and re-opened it when he had initially known nothing about mining - his grandfather had asked why was the mine closed and he'd just seen the potential and gone with it!

They even went and got a special rock saw from the Itialian marble quarries - this looks like lots of lumpy beads, or sort of an articulated spine of some sort - it is beds of steel or something embadded with industrial diamonds that as Jean point out glittered.

They now mine safely off course but when the mine was origonally open (from the 1700's I think he said but am not sure) they used dangerous tequniques which have resulted in what are known as rate traps - these are rooms where so much of the slate has been removed that the overlaying rock is in danger off coming down on top of the minners if they continue - this was actaully an inefficient way to do it and they get far more out and intact than they used too. Also the range of products they offer now will hopefully buffer them from economic crisis - these are what always closes slate mines as builders stop buying the slates.

One of these rat trap chambers turns out to have great acoustics and a jazz dude has been in there recording this has given me an idea - ok Clare, Ella and Charlee what about us doing something similar - I'm thinking medeaval chants with some electric guitar thrown in would be cool - Becca could even play some flute and Carina how's your guitar playing - infact Becca you play too don't you?

I think we could call ourselves the Mining Babes?

What do you think?

Anyway cough we had a look at the history and stuff and after me rabbiting on about why I thought the cieling of the place worked so well our guide thought that we were musicians but Al and Simon blew my cover and asked me questions about the geology of the place - I was highly embarassed but then it turned out Fred was a Steel Engineer and on top of that I found out that there may be something there that will help me with my MRes project. So I may be going back there sooner than later.

I really love this and Jeany announced that she likes tunnels 🙂 Talking of which there where a few really cool tunnels there that had been in the old days, shored up with the waste stone - this is done with no key stone and is similar to the ancienct burial mounds in Scotland and places. Jean told me off for touching the walls and braeking them which I thought was sweet 🙂 Somehow she ended up getting buscuits out of the other people on the tour :/ How does she do it?

Again photos coming soon hopefully 🙂

    Well I've been in the Essex Baebes, so the Mining Babes should be a doddle! 😉
