Working on this project as a civil engineering grad at the moment. To answer one of the questions the pits can be topped up from the nearby Copperfield river which is how they were filled initially.

It’s

Thank very much. Very interesting and very well explained and appreciate the clear pronunciation. Greetings from Spain.

15 minutes is terrible whoes going to stay behind that extra 5 minutes when high pressure water is cascading in

The whole video was great !

Great presentation Ricardo, well done!!

Good work 👍

at 22:59 Presumably arch 1 is english bonded to the rest of arch 1 and arch 1 is intermittent bonded to arch 2 right?

How did they keep y z level and straight x axis dig?

in Kenya a tunnel believed to have been built by Britons has been discovered in Mau forest,its about six(6)kilometers or so and apparently its untouched as most indigenous believe its risky..can you help please

These people are going to end up destroying earth as we know it

Good work Ahmed Shaz..

Can anyone tell me if they know anyone who can give some advice on filling in a disused rail tunnel. I am involved with a residents group and need some help.

please can I get British standard code for tunneling 6164:2019

Looks like , the best speaker was col sunny , his presentation is very clear one Long live BRO

Amazing lecture

Worst K Pop video ever

caeivm VUR.FYI

Thanks

Brilliant video . I found this after visiting pule hill today and admiring the tunnel shafts and engine houses there. One thing that I was surprised didn't get mentioned was how the depth of the tunnel was calculated, especially for tunnels on an incline such as the Queensbury tunnel where I live. A real shame this wasn't covered.

enjoyed that. really interesting

I would be more impressed if we didn't have to import all of our TBMs from Germany and actually tried to build some of them here.It has been estimated that we have had to purchase in the region of £200,000,000 of tunnelling equipment from Europe in the past 30 years.What the hell is wrong with our civil engineers.

Congratulations Francisco for the very interesting and well delivered presentation. A quick question from my side, are the Ventilation shafts also emergency exits or all the evacuation of the tunnel is designed to be via the stations?

Very interesting video.

CORRECTION : The next BTS Lecture is on 21 October 2021

Great presentation…

They should stop this program all together. God is real is made it all . That’s all they need to no

If you caught you supposed to retreat

Make sure that they keep that hicks field off of me now

wonderful presentation. Cuts straight to the point. no fluff. well done

Very good explanation. Thank You.

CERN should be like father go get food for his son

HI do you have any training course about(TBM) THANKS

In bangkok metro elevated section in orange line, at one location due to space condtraint metro tracks sre going one above other. Can you name that street or video of that

Dear professor,good informative

Thank you so much for sharing your experience Lok

What would you consider the top cost for 20 large hardrock TBM to drive Sydney/Canberra that Australia may be able to pay in Yuan.

Thanks so much for sharing your experience Lok and I as have firsthand experience where after much surface drilling we hit a huge fault 50m from pit bottom in a coal mine I understand how ineffective surface drilling is. Without service roads, fences, bridges or buying land I believe that it would be just as cheap to drive a single tunnel Sydney/Melbourne with initially Parramatta/Canberra using a proven 600km/h Japanese Maglev. If the ten launch shafts are approximately 20 km apart it may be faster to ascertain the exact geology by using a special directional drill that can go ten km using 10m rods and perhaps a remote hydraulic cylinder to push the cutting head as they can do 5km now ascelibrary.org/doi/abs/10.1061/9780784482490.075

awesome presentation!

Thanks Keith - many thoughts on where we go as an underground excavation industry universally. Where, do you think, are the pinch points for being aware, as a client, to know how to buy the very best of underground excavation infrastructure possible - in all regards

Thanks Matthias for this lecture. Thanks for sharing all your knowledge about this important subject. Best regards

Very informative, is there anywhere I can go to research one tunnel in particular? Bolsover being the one in question, thankyou.

Presumably because they used the wires down the shaft to enable them to maintain the correct bearing / alignment of the tunnel - shafts off set would mean that the setting out of the tunnel would be too difficult

Thank you BTS for these two great presentations ...

Highly informative!

Interesting talk. Thanks for posting.
