O.T. Underground coal gasification

[Adam Aglionby]

Few licences have been granted in U.K., puff piece about in on eof the papers business pages, The Coal Authority and Enviroment agency seem to be happy clappy about the idea:

friendly sounding Clean Coal Ltd:

such indepth authorative analysis as

`idea of UCG is that you find coal seams which are up to 500m (1,641 ft) underground - far too deep to mine`

Its statistics like that , that make me wonder of anyone has done any research at all....

Too deep to mine?

"Kellingley Colliery is the largest remaining deep mine in Yorkshire and began production in April 1965. Up to 900 tonnes of coal an hour can be brought to the surface through one of two 800 metres deep shafts. The 'Beeston' coal seam, which is currently being mined, will last until at least 2015 after which further reserves will be accessible in the 'Silkstone' coal seam."

The nearest mine tunnel to where I live is just over a mile away. Straight down. That was the highest level still being worked when the pit was closed down, leaving 200 years of reserves in the ground. Other tunnels went a further half mile further down.

Maybe they meant to say 5 km. What is a factor of 10 among friends?

It is in a media report. Of course they haven't done any research.

C4 news falls for similar twaddle "Sending miners down under the sea would never be viable" course not , that s why loads of deep mines extended below the sea bed then.

Being spoon fed a story from a company almost doing a phoenix.

"Following a corporate restructuring, CCL is now owned by its directors and is now embarking on a new additional advisory role where CCL will advise third parties as well as having a trailing equity interest in those projects."

needing the upfront fees rather than the trailing equity liability , mean interest , as elephant in room , apart from groundwater contamination , is CO2 emissions, which is why they have `restructured` since 2010

it goes wrong Swansea becomes Centralia

it isn`t all bad ;-)

now would you - even though that is much closer to the reality. Coal gas production by thermal decompostion was always an evil process.

Underground gasifcation is only clean on an out of sight out of mind basis. With any luck the junk byproducts will stay put down there.

Civil servants and journalists don't do numbers or science. What do you expect? Probably a decimal point error 5000m maybe.

Are there any UK "deep coal mines" as shallow as 500m these days? I though the remaining big ones were all 600-800m now.

Bellona thinks that coal is a good idea. I think that coal is very dirty and that nuclear is clean.

Did not find an english version of this:

thinks that the world has 900 000 000 000 tonn of coal. Statoil has found 3000 000 000 000 tonn of coal at Haltenbanken

A lot has to do with the quality of the coal and if it is an existing mine and there may be more than one coal seam. But most of all, if itcan be bought more cheaply elsewhere.

Bit more on the topic here.

deep mined seams are up to 5m thick. The Silkstone seam is described as a high quality, low sulphur coal used for coke manufacture and as a manufacturing and household coal. There are plenty of other seams in the area that are not worked, either because they are too thin or the rock above them is unstable, making them unsafe to mine, or because the quality of the coal is poor and / or it is mixed with shale and dirt.
