Andy Wright, BA, MSc
Geologist

• Geological/Mining Assessment: Desk top investigation of mining history and future mineral potential of a large landholding in Yorkshire. Assessment of reserves of opencast coal, clay and brick shales.
• Site Investigation of contaminated development land on former industrial areas.
• PPC Applications: Preparation of documents for Pollution Prevention and Control applications to the Environment Agency for waste disposal sites in Yorkshire.
• Environmental Risk Assessment: Desk top studies of land parcels in former coal mining areas, indicating potential hazards to future development and potential liabilities from former uses of the land.
• Sheffield City Airport: Prospecting, geological modelling and assessment of the opencast coal reserves under a derelict steelworks. Opencast mine design and restoration design of the landform for the Sheffield City Airport. Following the recovery of 1.5 million tonnes of coal, the airport became operational in 1997.
• Geological Modelling and Prospecting: Many and various UK opencast coal reserves, ranging in size up to six million tonnes. Projects often involved steeply dipping and/or heavily faulted strata, multi-seam prospects and multi-layer old workings.
