Colliery tip landslip
Look like it was a good job this was spotted before a train ran into it.

Re: Colliery tip landslip
The local news are reporting that the landslip is still moving, so engineers are not going to do any more inspections ........it may be "at least two months" before the line re-opens.
Re: Colliery tip landslip
Looking at one of the aerial shots of the heap on the NWR website.
It shows cracking a long way back from the slip front edge, this to me would suggest that the inside of the heap must be totally saturated and ready to move a lot further leaving a pudding bowl like slip in the heap.

As has been said 8 weeks disruption at least to services between Doncaster - Goole and Scunthorpe. At least the freights to Immingham do have a divert route so Wrawby - Gainsborough might be a bit busy for a while.

Re: Colliery tip landslip
It does look like a rotation slope failure, doesn't it? (hence it coming up under the rails).
They think it will stop moving in a couple of weeks? I guess they haven't heard of Mam Tor...
Still moving even though they abandoned the A road back in the 1970s!

Re: Colliery tip landslip
looks as though there was a lake in that light grey area judging by the rings round it also strange is that water coarse which appears to be coming from a culvert under the railway embankment which is in the middle of the slippageBryan wrote:Looking at one of the aerial shots of the heap on the NWR website.

Re: Colliery tip landslip
And more photos - it is still moving:

This blog appears to confirm my initial diagnosis of a rotational failure.
8 weeks after the colliery have fixed the tip. That line is going to be closed for quite a while...
I can already imagine the Engineering Geology papers that will be published next year... lol

Re: Colliery tip landslip
I was due to go over that section of line the day after the intial disturbance was spotted
It's a good job it was noted before it all went pear shaped!
I doubt the line would have been open at present regardless of this landslide - NR is out in force working on Scunthorpe viaduct again, with half the remaining structure on the Eastern side of Scotter road covered in scaffolding. Work is still ongoing with the Eastern embankments visible from Scotter road, brumby wood lane, Scunthorpe general hospital staff car park and station bridge. The only complete arch left is that above Scotter road, the rest of the viaduct's arches either having concrete supports or being filled in with concrete and embankments being built up. The bulk of the work has finished, but as stated, they keep tinkering with the remaining section and the Eastern embankments with the odd disruption to services every now and then.

Re: Colliery tip landslip
Found this apparent technical explanation. I will leave you to judge.

What a mess, think your talking months to clean that up, seems that the lesson they learnt after Aberfan, have been totally forgotten ??????

Re: Colliery tip landslip
Dr Dave (cf the AGU link that a couple of us have posted) has suggested that Aberfan is what makes this event so unexpected in the UK.

Re: Colliery tip landslip
In an accompanying article about Aberfan, it reports on the shameful behaviour of the then National Coal Board, its chairman, and the UK government. It also states the following:
The Aberfan Disaster also led to detailed studies of the behaviour of mine waste, and in particular of their potential to undergo apparently spontaneous catastrophic collapse. Research into this mechanism continues today, but sadly mine waste failures remain common, especially in less developed countries. For example, in September 2008 a mine waste landslide struck the village of Taoshi in the Shaanxi province of China, killing at least 128 villagers. Of course, in the UK the disaster led to major changes to the ways in which mine wastes are managed, and there has been no repeat of this dreadful accident. Since the accident, coal spoil tips have been treated as engineering structures requiring proper design and maintenance. A Derelict Land Unit was setup in Cardiff not long after the disaster to restore brownfield land, including former sites of collieries and land used by the coal industry. New ways to dispose of colliery spoils have also been developed.
You have to wonder if due diligence and engineering protocols were followed in the planning and siting of the Stainforth tip. Thank God no lives were lost.
