JGI Geo-Services Ltd has been commissioned 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 series 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.
JGI Geo-Services Ltd was commissioned to carry out a risk assessment for highways maintenance workers potential exposure to naturally enriched Arsenic within the Jurassic Marlstone Rock Bed on a development site in the east of England. Naturally enriched concentrations of Arsenic are a characteristic of a number of geological formations, of various ages, scattered throughout the United Kingdom. In this instance, the Arsenic concentrations were up to almost 200mg/kg, but concentrations of up to 1,500 mg /kg have been encountered in other parts of the UK. JGI Geo-Services Ltd has extensive experience of assessing the risks posed by such natural geochemical enrichment of Arsenic and indeed other metals, to encourage development on affected sites.
JGI Geo-Services Ltd was commissioned to complete a Phase II ground investigation of a proposed residential development in Cambridgeshire. The site comprised the final phase of a development site. The whole development site had previously been the subject of a Phase I Geo-Environmental Assessment by other consultants, who had also undertaken a Phase II investigation of the other phases of this development.
