Minewater remediation in the United Kingdom

Philpott K. D.

Polish Geological Institute Special Papers

2002

Vol. 7

207-214

The author will outline the history of minewater remediation in the UK with special reference to investigations and construction schemes undertaken by SRK in England, Scotland and Wales over the past seven years. The influence of mining and geology on the waters, the flow of minewater and its discharge location, and then the subsequent choice of remediation methodology, site and construction option will be examined at specific sites. At Polkemmet Colliery in Scotland rising minewater was prevented from discharging in an uncontrolled manner by installing pumps into an old mine shaft and constructing a semi-active treatment plant on site before discharging the water to a nearby stream. Edmondsley remediation scheme in County Durham involves the treatment of a ferruginous discharge from a drainage adit by the pumping of minewater through a woodland nature reserve up to a three cell wetland, and then by gravity return to a nearby stream. In Derbyshire, the Fender scheme has recently been constructed and involves treatment through reedbeds sited on former colliery and ironworks tips with the water first being pumped across an existing river from shafts sited in the yard of a factory unit. At Blaenavon construction has recently commenced. The scheme involves the capture and piping of two ferruginous minewater flows underground and then treatment through reedbeds. The water flows through Big Pit, a former mine reopened to the public as a tourist attraction.

Evaluation of the Bogdanka Mine, Poland

During the early part of 1999 Steffen, Robertson and Kirsten (UK) Ltd (SRK) were commissioned by Price Waterhouse Coopers to carry out the technical due diligence study of the Bogdanka Coal Mine as part of their contract with the Treasury Ministry of Poland for pre-privatisation analysis. A visit was undertaken by four experienced consultants specialising in the fields of geology, mining, coal preparation and environment. The team also undertook a review of management, manning levels, performance and other broad issues affecting the operation of the mine. In this paper the author outlines the general geology of the mine, and attempts to show how an experienced consultant comes to terms with a meaningful assessment of a mine and coalfield of which he has little or no previous knowledge, particularly given the very short time available for the commission.The relevance of such aspects as mineral rights and concessions, the exploration history, cover deposits, coal bearing strata, geological structure, coal quality and potential hazards to the assessment will be examined. The assessment of reserves and resources to standards acceptable to international banking organisations will be looked at in more detail. Finally some of the critical non-geological factors of the assessment will be outlined.
