About this event

York Potash Limited (YPL) intend to build the first potash mine in the UK for over 40 years – a plan for North Yorkshire that has both local and national significance. A state-of-the-art new mine to extract polyhalite, a unique multi-nutrient form of potash, will not only safeguard UK supplies, but also boost the local, regional and UK national economies.

YPL have already made significant progress towards delivering this vision. The exploration programme has confirmed that the project area has the world's thickest and highest grade of polyhalite and the planning process is now underway for one of the world's most innovatively designed low impact mining operations.

Once the polyhalite is mined it is brought to a depth of 360m where it is loaded directly onto a conveyor belt. From the mine this travels approximately 37km until it rises to surface at Teesside. The conveyor belt sits in a mining tunnel which will follow a stable geological sequence that naturally comes to surface at Teesside.

The talk describes the proposed mine and ground investigations carried out to date, and discusses the various geological, geotechnical and hydrogeological aspects of the tunnel investigations.

Registration and Refreshments from 5.30pm for a 6.00pm start.

Tom Berry

I am an engineering geologist with over 20 years' experience and a passion for what seems to be the two extremes of geology; 'deep geology' for tunnels, geothermal and shale gas as well as shallow Quaternary geology.

I currently lead an applied geology team in York, and jointly lead Arup's Deep Geology capability. I am the industrial supervisor for 2 doctoral research projects in the performance of discontinuities at elevated temperatures and pressures and infrastructure resilience associated with the geology and geotechnical properties of Quaternary sediments.

I have been fortunate enough to have worked on some amazing projects around the world including HS1 (UK), Oresund Link (Denmark-Sweden), Heathrow Terminal 5 (UK), Forth Replacement Crossing (UK), Various LPG tanks (Indonesia & Philippines), California High Speed Rail (USA) and Lake Mead third Straw (USA), the A303 Stonehenge bypass tunnel (UK) and the York Potash Limited Mineral Transport System (UK) that I am going to talk about at this event.

Asher Haynes

I work on the Sirius Minerals owner's team as a graduate geologist, working closely with Tom to plan and implement the project's ground investigation campaigns.

As a geology student from the local area I was privileged to be given a place on the company's undergraduate development programme which has given me an amazing opportunity to begin my professional career with a nationally significant project.
