| Abstract: | A commitment by the National Coal Board Opencast Executive to restore opencast coal areas to agricultural use as efficiently as possible recognizes the need for continual improvement in techniques. The Department of Agriculture and Fisheries for Scotland, as agents to the National Coal Board Opencast Executive, share a similar objective. Both organizations appreciate the need for a comprehensive soil survey, but experience has shown that general-purpose maps and reports are not always adequate for use in opencast mining operations.A soil survey of a proposed site at Keirsbeath is described and, on the basis of results from the use of improved survey methodology, and computer techniques to analyse the data, interpretative maps have been produced. The procedures, together with an examination of soil quantities available for restoration, and of critical moisture levels in soil stripping, are an improvement with significance for the planning and development work stage. A scheme of soil operations has been presented and the relevance of soil data to the forthcoming restoration and rehabilitation stages is discussed. |
