ECTON MINE NEWS

Dec.2023 Balance Cone Restoration

Ecton Mine Educational Trust, supported by a FIPL grant from the Peak District National Park Authority, is undertaking restoration of the Ecton engine balance cone. Cutting edge technology in the 1780s, the Ecton engine, built by Bolton and Watt wound copper ore from depths of up to 300m. At the peak of its production in the late 18th century this was the deepest mine in England. The balance cone shaft housed a counterbalance to support some of the weight of the winding rope and reduce the load on the steam engine which was the sixth ever to be commissioned in 1788. Restoration of the balance cone is the final part in preservation of the extensive historic mine site that is considered at risk by Historic England. The Ecton mines are maintained by EMET to facilitate education in the skills needed to provide current hi-tech materials that support the transition to a low carbon economy – a continuation of the role of the mine for the past three thousand years.

The restoration work is carried out under a contract with The Morton Partnership Ltd, project-managed by Lucy Newport. Conservation and construction work is being carried out by Derbyshire Geotechnical Ltd (D-Geo). From the detailed structural investigations required, we have already learned a great deal: in particular that it is not simply a ‘beehive’ pile of rocks and rubble, but has an interesting history that needs to be (and will be!) properly documented.

17 Sept.2023 Heritage Open Day

Deep Ecton was a hive of activity on Sunday 17th September, with a total of 114 visitors underground in 10 guided tours of Deep Ecton followed at the Geoff Cox Study Centre by tea, coffee and videos and a Q&A session with John Barnatt on the history and archaeology of Ecton. The visitor numbers are almost double those of the same event last year, organised in partnership with the Peak District Mines Historical Society.

Ecton Hill is an Ethel !

You may know of the Munros – the highest peaks in Scotland. Well the Peak District has its Ethels to climb. Ecton Hill is one of them! Named after Ethel Haythornthwaite, environmental campaigner and pioneer of the countryside movement. Come to Ecton and bag an Ethel!

Carlson SW is a leading provider of high tech survey equipment and software. The Carlson team visited Ecton to test the latest borehole survey equipment which they have developed.
A slipring cable drum, with winch, lowered a probe through the 70 mm hole in the main winding shaft cap. The probe was lowered down to Deep Ecton level and was able to provide pictures, video and survey scans of the shaft. Further work was done in Salts level to test the high powered light and camera system fitted to the probe.
EMET can provide mine locations and assistance for testing equipment in an environment which is free from the production constraints that are found in working mines.

A new video on Youtube from the 2022 UNEXUP project visit to Ecton. And one that was produced immediately after the visit: Navigating through Ecton

10 Dec 2022

In October 2022 EMET purchased the Balance Cone land, historically known as the Winch Cone, from a local farmer. The Balance Cone is a Scheduled Monument and is a unique surviving historic stone structure in the UK (it was built around a shaft used for a balancing weight to assist operation of the adjacent winding shaft). The objective of the purchase was to enable EMET to apply for a FiPL (Farming in Protected Landscapes) grant to initially survey and assess the stability of the stone structure and then as a second stage, carry out remedial works to repair the structure and ensure the long term stability of the structure for the nation.

Currently assessment of the stability of the structure is underway.

The final UNEXUP project conference was held in Brussels on 18th November, and the results of robot and ROV dives at Ecton during 2021 and 2022 were presented. These included three series of dives by the BlueROV2 comercial submersible, and the March 2022 dives of the UX1-NEO robot.

On 20-21 September, there was a series of four further dives using the BlueROV2 submersible, in the winding and pumping shafts and in the pipe workings, to test the capabilities of this ROV which was acquired for the project to carry out preliminary assessment of proposed dive sites for the UX1 series of robotic submersibles. These dives were also specified to address a number of archaeological and geological questions at Ecton Mine, and achieved some very interesting results, including proof of a postulated stepped ladderway from the Deep Ecton adit level into the main pipe workings.

17 Sept 2022

Heritage Open Day: this was an event organised by the Peak District Mines Historical Society, and EMET provided tours of Deep Ecton adit level. During the day, six scheduled tours took place, with a total of over 60 visitors seeing parts of the mine that are rarely open to such visits – followed by tea and cakes at the Training Centre.

22 May 2022

From 21-23 March there was a second visit by the UNEXMIN team, now in the follow-up project UNEXUP, deploying the new UX1-NEO submersible robot at Ecton. There were three dives: on 22 March in the pumping shaft, to explore and survey some workings that had been discovered in 2019; and two dives on 23 March in the winding shaft. The first of these went to the blockage at the accessible bottom of the shaft, to explore workings that had been identified in 2019: there was some drama during the ascent when a length of what appeared to be nylon fishing line in the shaft became entangled in the robot’s thrusters. The final dive passed through a ‘window’ in the eastern side of the shaft, into the upper pipe workings, and explored these to the north beyond the area that had been visited in 2019. A large quantity of data was obtained from these dive, and the results of interpretation will be published in due course.

Something completely new for Ecton: the excellent acoustic properties of the pump and whim chambers were tested by choral singing. The West Bridgford Male Voice Choir sang at Ecton, a selection of mining songs! This was recorded, and the recordings can be heard here. Or you can listen to a short promotional video These songs were recorded to raise funds for charities supported by the West Bridgford choirs. Please contact EMET secretary Phil Read if you are interested in donating.

 

 

30 September 2021

After several months in which the mine was strictly closed due to the pandemic, some activities are re-starting. On 28-30 September, we tested a new submersible ROV (remote-operated vehicle) acquired for the UNEXUP project for preliminary assessment of sites before use of the expensive and virtually irreplaceable UX1-NEO robot. On 28th Sept, initial tests were done in open water at Rudyard Lake. Despite very wet weather, a number of hardware and software bugs were identified and fixed, and the weight distribution was adjusted to give neutral buoyancy for maximum manoeuvrability. Then on 29th and 30th Sept., the ROV was deployed in the pipe workings. Advantage was taken to carry out new exploration in areas not visited by the UNEXMIN project. New discoveries were made, which will be documented separately. The ROV dived to 25m depth – at which water entered through a badly sealed lighting unit – but after fixing the leak, several further dives were completely successful.

Article about UNEXMIN at Ecton in the Buxton Advertiser

June 2019

The month of May saw Ecton study centre become a version of Houston Mission control, with the UNEXMIN submersible robots diving into the depths of the mine. A shipping container was rented for the month to act as secure storage as well as an engineering workshop to carry out maintenance of the two robots which were used. EMET had constructed launch platforms at three sites underground: the Great Shaft, the winding shaft, and the pipe workings. Altogether ten dives were achieved, and an enormous volume of new data were obtained including literally millions of images from the five cameras mounted on each robot, as well as scientific data from on-board instruments. Shafts, cross-cuts, and mined-out regions were mapped in detail by sonar and structured-light sources (laser stripes).

Geology and archaeology have yielded a number of surprises among the high-qualty data recovered, which EMET and UNEXMIN consortium scientists will be working on for years to come. Among the many highlights of the month, Ruth George MP (Labour, High Peak) paid a visit and saw the robots in operation underground as well as at Mission Control.

19 November 2018

Mark Hudson of Geoterra brought his Nautilus ROV to Ecton for a preliminary exploration of two of the shafts and the pipe. The first dive was in the pumping shaft, with the ROV descending to about 50 metres depth. No serious obstacles were encountered, though it found a few timbers including the remains of some staging which might be a hazard for UNEXMIN as there appear to be a number of loose rocks.

At times, visibility was affected by a large amount of calcite ‘snow’ – from calcite that crystallises on the water surface and sinks whenever disturbed. It accumulates on the sides and any horizontal surfaces within the shaft, and movement of the ROV disturbed it. Care will need to be taken to avoid such disturbance as much as possible in the UNEXMIN trials. In the winding shaft and the pipe, the water was much clearer. Geometry of the pipe is more complex than it appears from surface, and the ROV only explored to fairly shallow depths to avoid risk of snagging the umbilical cable. It appears that there may be at least two routes leading downwards, as well as side passages. There is much for UNEXMIN to explore!

November 2018

Major works have now been completed, on restoration of the entrance to Deep Ecton adit, which was becoming structurally unsafe. This work was carried out by a local contractor D-Geo, overseen on behalf of EMET by Nick Hardie of Hard Rock Mining Ltd, with the arching rebuild led by Peter Roe a master mason from Swaledale. The work was monitored by John Barnatt, who did the archaeological watching brief that was a requirement of Historic England, as the entrance lies within a Scheduled Monument.

John Barnatt’s full archaeological report is available here. A summary will also be published in Mining History in due course.

26 June 2018

Richard Shaw of EMET was in Finland this month for the first live trials of the UNEXMIN submersible, in the flooded Kaatiala pegmatite mine. His specific focus was to see the launch and recovery methods, which are likely to be similar to those that will be needed at Ecton. Launching used a standard small hydraulic crane.

6 May 2018

In preparation for the UNEXMIN pilot tests to take place in 2019, it is necessary to rebuild the stone arching of the outermost few metres of the Deep Ecton adit. This is to be done by a ‘cut and cover’ method, digging a trench, rebuilding the stone arch, and then re-filling the trench. This will necessitate partial or complete demolition of a small ruined stone building which was originally a part of a dairy/creamery complex on this site. Before this can be done, we need to make a detailed archaeological record. This will consist of a series of photographs, and we also plan to produce a 3D model from a large set of photographs of the exterior and interior of the building, using Photomodeller software, which we previously used to generate a 3D model of the dressing-floor wall. A preliminary set of photographs were taken for this purpose on 4th May, and a further series of photos may be taken when the trees around the northern gable end have been removed.

29 Sept 2017

Over the summer, a ground penetrating radar (GPR) survey was carried out over the top of Ecton Hill by TerraVision with the principal purpose of locating any previously undetected ancient shallow underground mine workings. A number of traverses crossed the area in which these were suspected and in which some known workings had already been identified. Apart from detecting very clearly these known workings, a number of new targets were identified. Although most of these are too deep for archaeological excavation, the Trust now has an opportunity to try to match them against existing surveys. The GPR work also provided unexpected evidence of geological structures on the hill which potentially can be linked with geology observed in the accessible underground workings. The survey was carried out by Natalie Staffurth and Daniel Sherwin of Terravision, and Dan’s later de-briefing session with us was very much appreciated!

5 August 2017

Filming in Deep Ecton: On 1st August a team from Boomerang visited Deep Ecton to carry out filming underground for a documentary series they are making, intended for broadcast on Channel 5 later this year. This coincided with another visit by Mark Hudson of Geoterra, as well as Stuart Cadge of GeoSLAM, for further laser scanning for 3D computer modelling of accessible parts of Ecton Mine, in connection with the UNEXMIN project.

1 July 2017

Laser scan survey of Deep Ecton and Salts Level: On 27th and 28th June 2017, Mark Hudson, MD of Geoterra, assisted by John Barnatt and Richard Shaw of EMET, carried out a full laser scan of the accessible parts of Deep Ecton, the ladderway, and Salts Level. Preliminary images show that the survey has produced an excellent 3D model, for the first time linking the two levels with an accurate and detailed graphical representation, and providing data to be combined with a 3D survey of the flooded parts of the mine (which we expect to obtain from the UNEXMIN project).

4 May 2016

UNEXMIN consortium visit to Deep Ecton: On 3rd May 2016, there was a visit to Ecton by members of the UNEXMIN consortium to help them decide on some details of the robot design and on methods for transport, launch, and recovery of the robot.

31 March 2016

Dressing floor progress – 3D model from photos. On 22 March 2016, Mike McLoughlin of Rockmate Ltd visited Ecton Mine to run tests of software to generate 3D computer models from a series of overlapping photographs. From 49 overlapping high-resolution photos of the restored dressing-floor wall he was able to produce a detailed 3D model, which he has made available to EMET.

Historic Ecton Copper Mine in Staffordshire Receives EU Research Project Funding

Ecton Mine Educational Trust (EMET) has become a consortium member for the €4M (£3.5M) UNEXMIN project for underwater exploration of flooded mines using submersible remote-controlled robots, miniaturised and adapted from deep sea technology. It will enable a full survey of the submerged workings, to gain geological and archaeological information.
The 4-year project with 13 consortium members from 7 EU countries has just received the go-ahead from the European Commission and will enable new technology to develop potential strategies to re-work some of Europe’s currently abandoned mines many of which may still contain critical raw materials vital for the UK and Europe’s economy.

It starts with a meeting in February 2016 at Miskolc University, Hungary, who are coordinating the project. This is followed by pilot deployments at mines in Finland, Portugal and Slovenia in progressively more challenging conditions concluding with a full-scale study at Ecton in early 2018.

1 Feb 2016: Dressing Floor Discoveries

This is just a preliminary note. Archaeological work on the wall behind the Dressing Floors has revealed ore hoppers and ore chutes whose presence had not been suspected. At least one is very well preserved, including the wood of the ore chute – last used more than 100 years ago.

2015: Boulton & Watt engine house at Ecton

Over the last few months, intensive archaeological and restoration work has been carried out on the engine house, by the National Trust in collaboration with the Peak National Park Authority, and volunteers. On Friday 6th June there was a formal ‘opening’ by Francis Pryor MBE (the Time Team archaeologist), at which the restoration and archaeological work were shown and explained by Paul Mortimer (NT), John Barnatt (PDNPA), and colleagues in both organisations as well as EMET and EHFSA. Both outside and inside the building, the National Trust has erected a series of explanatory boards which interpret the history and explain the engineering and geological features, as well as the broader environmental context of the Ecton area.
