JGI Geo-Services Ltd has a term appointment to carry out stability assessments of multiple quarry excavations and active & closed tips under the Quarries Regulations 1999 and the Mines & Quarries (Tips) Regulations 1971 at a number of slate mines in North Wales. Slate mining has been undertaken on these mine sites for nearly 200 years, originally by predominantly underground working, but latterly, almost exclusively by surface quarrying. The current quarries are extracting pillars of slate left to support the roof in the former underground workings. The size of the quarries and tips are substantial, with the quarries up to 85m deep and tips up to 90m high.
