Now then now then, how is the digging going are we close...or still another 3 years, blimey we could be out of EU by then or not, who knows.

RNS for Director buy today, dont get 2 excited only £2k's worth.

[hazl] 12/6/2018 15:53

YES still got some....just a bit range-bound as somebody said.

[redips2] 12/6/2018 15:51

.... always here... just watching 'n waiting .

North East achieves fastest output growth since January

Manufacturing remained a bright spot for the North East, according to the latest survey data. The upturn in order books at manufacturing firms was driven by improving business conditions in key export markets and rising global demand for capital goods.

The main positive finding from the latest survey was a rebound in North East business expectations to the highest since March 2016. Manufacturers cited new product launches and plans to boost export sales, while service providers noted hopes of improved operating efficiency and a rebound in consumer demand.

Too tight a spread for me.........am looking for the 30-40% rise/falls.

Goose... let's try it then...Out at 34.7.. back in 34.1.. a good few ..This a few times a day looks possible xx

The Sirius Woodsmith Mine polyhalite seam has an average thickness of 25m but is up to 70m at its thickest point and it is at its maximum thickness – below Woodsmith - that the main mine workings are being developed.

The Sirius Woodsmith Mine polyhalite seam has an average thickness of 25m but is up to 70m at its thickest point and it is at its maximum thickness – below Woodsmith - that the main mine workings are being developed.

The development involves three shafts from ground level at Woodsmith: one for production, another for services and the other for launching of the 5m diameter tunnel boring machines (TBM) that will drive the first section of the 37km material transport system (MTS) tunnel at 360m depth from Woodsmith to Teeside. There is an intermediate shaft at Lockwood Beck from which a second tunnel boring machine will be launched towards Woodsmith. The third TBM, working under a contract recently awarded to Strabag, will be launched from a ramp at Wilton and complete the drive to Lockwood Beck.

The production and service shafts at Woodsmith will extend from the surface to 60m below ground level as 36m diameter chambers with a central 9m diameter shaft extending to the polyhalite seam at 1.5km below ground. The MTS shaft from which the TBM will be launched will extend to 360m and connect to the production and service shafts.

The initial plan was for Bauer to construct six diaphragm wall shafts on the project to include the production and services chambers and take the production, service, MTS and Lockwood Beck shafts to120m, from where they were to be extended to 1.5km by drill and blast techniques.

In February, Sirius announced that it had changed approach for the extension of the shafts andw ould no longer be working with contractor AMC which had been developing a drill and blast system under an early contractor engagement process. Instead, the contract was awarded to DMC, which will use a shaft boring roadheader from Herrenknecht.

“AMC’s approach would have been slower and also had potential issues with health and safety,” says Sirius Minerals corporate communications general manager Maurice Rankin. “The roadheader proposed by DMC has been used in Canada on a similar scheme but never in the UK before.”

Bauer has three cutters on the project – two MC96 machinesand an MC128.
MC96 machines

Bauer’s two 36m shafts are formed by 2.8m wide, 1.2m thick and 60m deep panels – 48 for the service shaft and 44 for the production shaft.

The design of the structures is based on hoop force with steel cages extending to the full depth. The cages used in the primary panels are slightly smaller than those in the secondary panels to allow for overbiting.

The cages are manufactured offsite in six sections which are assembled vertically before being installed the panels.

The large diameter of the shaft means that sequencing is key with Bou-Sleiman aiming to have a maximum of ten days between the construction of a primary panel and its adjacent secondary panel.

Verticality is a challenge too with a maximum deviation of 200mm over the 60m depth of the chamber.

“We are well within these tolerances,” says Bou-Sleiman. “We are using a combination of techniques – CIS technology surveys the machine ropes, kodens are used within the panel and the machine operator also has verticality displays within the cab.”

The service shaft has been used to develop the technique and Bauer expects to complete the structure as this issue of GE went to press. Work will then start on the production chamber and Bauer expects to complete that by October.

The location of the site within the North York Moors National Park has impacted on the approach to construction, as well as the final operation of the site. Sirius has set up a Liebherr concrete plant on site to ensure the 55MPa concrete is not delayed en route to the site and Bauer has had to use shorter, larger diameter silos for the bentonite plant and also paint them a specific hue of green to blend in.
According to Bou-Sleiman the plant is probably the largest in the UK with 1,600m3/he desanding capacity and 4,000m3 of bentonite storage.

6 June, 2018

The Datum Group has been awarded the instrumentation and monitoring contract for the Sirius Minerals’ £2.2bn polyhalite mine development in North Yorkshire.

Datum will provide instrumentation and monitoring for the main diaphragm wall circular 60m deep shafts, being installed by Bauer Technologies for Woodsmith Mine.

The monitoring solution has been created specifically for Bauer Technologies and will see Datum install sensor arrays to measure the performance of the shafts for design verification.

Datum’s online data management system Platform Interactive (PI) will be used to collate and interactively present data from many hundreds of strain gauges and in-place inclinometers.

PI will allow all stakeholders access to the data in real time.

Datum Group CEO Rory O’Rourke said: “Datum is delighted to have been appointed to this prestigious and complex project and is proud to be working with Bauer Technologies to provide the best solution for Sirius Minerals. I was born and bred in Teesside, and to be part of the biggest industrial project in the area is a real honour”.

Bauer Technologies managing director Martin Blower said: “It is essential to the programme and running of the project that Bauer appointed a reputable and experienced monitoring company, Datum has vast experience in providing monitoring solutions and we are confident that they will deliver the hi-tech, innovative monitoring system that this project demands”.

Not following SXX at the moment.......just seems a bit close to 35....

Still like the rise at the open.

Yes, seems a bit range bound 33-35.......share shuffle?????...could be.


Too busy trading oil...its going over $80 again.....try 5WTI, although its Brent that is rising.

Also occupied buying a house to rent.....

And gold, going down, for another P&D by central banks/gold banks..

Goose... Took a trade at 34.7...Maybe buy big around 34 and sell 34.5... frequently ... thoughts ?? X

Poor old Johnidiot.....lol.

I blame the unashamed virtue signaling snowflake NMRN for this.
