What we do Outdoor Leader Training & Events Workshop Providers Mine Exploring with Groups In some parts of the country like North Wales, The Lakes and Sussex there are no caves. For some outdoor centres and organisations working with young people this is one of the more exciting activities on the programme. We will visit an old stone mine and see how it worked, see artifacts and perhaps understand hazards. Find out how Long Wall Mining works and what is a pressure arch. Come just to see the mine or understand how it can be used for groups. Level of difficulty: Easy. All equipment provided by Hollowford. Limited to 10 places. Dave Baines runs cave and mine leader training for the British Caving Association in Wales, Derbyshire and the North Pennines. He has been a stakeholder in a lead mine project and has explored mines all over Britain.
