    Notes: Abstract  Contaminated and possibly hazardous ground represents a problem in all of the industrialized countries of the world. The investigation of a site that is suspected of being contaminated differs somewhat from a routine site investigation. Sampling of soils, groundwater and gas-producing material may be required. Various precautions may be necessary in doing this and operatives may have to wear protective clothing. Four case histories have been chosen to illustrate different aspects of the rehabilitation of abandoned contaminated land, namely, investigation, assessment, ground treatment and redevelopment. The first comes from Leeds in West Yorkshire, England, and outlines how a site investigation was undertaken and the nature of the contamination present, together with a note on the suggested redevelopment. The remaining three case histories are taken from the heavily industrialized district of the Ruhr in Germany, where extensive mining of coal and associated industries were developed from the mid-19th century onwards. The first considers the site of the former Graf Moltke mine near Essen. In this instance, the somewhat novel methods of data assessment and ground treatment are dealt with. The Mont Cenis site at Herne-Sodingen is one of the more notable old mining/industrial sites undergoing redevelopment in the state of North Rhine Westphalia. Hence, the case history concentrates of this aspect of rehabilitation. This involves not only the construction of new and interesting structures but an attempt to reduce energy consumption in an attempt to effect the concept of sustainable development of an urban area. The last example deals with the abandoned site of the Minister Achenbach mine at Lünen, where the ground conditions were further complicated by the presence of old bomb craters that had been filled with a variety of materials. In addition, because of the suspected presence of former foundation structures in the ground an electromagnetic survey was carried out across part of the site, the areas of high conductivity suggesting their presence.

    Notes: Abstract  The impact of mining subsidence on the environment can occasionally be very catastrophic, destroying property and even leading to the loss of life. Usually, however, such subsidence gives rise to varying degrees of structural damage that can range from slight to very severe. Different types of mineral deposits have been mined in different ways and this determines the nature of the associated subsidence. Some mining methods result in contemporaneous subsidence whereas, with others, subsidence may occur long after the mine workings have been abandoned. In the latter instance, it is more or less impossible to predict the effects or timing of subsidence. A number of different mineral deposits have been chosen to illustrate the different types of associated subsidence that result and the problems that arise. The examples provided are gold mining in the Johannesburg area; bord and pillar mining of coal in the Witbank Coalfield, South Africa; longwall mining of coal in the Ruhr district; mining of chalk and limestone in Suffolk and the West Midlands, respectively; and solution mining of salt in Cheshire. These mineral deposits have often been worked for more than 100 years and, therefore, a major problem results from abandoned mines, especially those at shallow depth, the presence of which is unrecorded. Abandoned mines at shallow depth can represent a serious problem in areas that are being developed or redeveloped. Abstraction of natural brine has given rise to subsidence with its own particular problems and cannot be predicted. Although such abstraction is now inconsequential in Cheshire, dereliction associated with past subsidence still remains.

    Description / Table of Contents: Résumé Les sites abandonnés constituent une ressource gaspillée et présentent un effet dégradant sur les régions avoisinantes. C'est pourquoi leur restauration est hautement souhaitable. Quatre études de cas concernant différents aspects de l'abandon et de la restauration sont présentées. Le premier exemple se rapporte à deux vieux terrils du sud du Yorkshire (Angleterre), qui furent restaurés, une partie du site étant aménagé pour une boulangerie tandis que le reste était transformé en espace naturel. De tels travaux de restauration conduisent à des mouvements de terres à grande échelle pour obtenir de nouvelles formes topographiques. Après terrassement des matériaux, installation de drainages et labour, les produits de terril ont été traités à la chaux et recouverts d'un sol. Des engrais ont été répandus avant ensemencement et plantation. L'exemple suivant est relatif à une exploitation abandonnée de sables et graviers de l'ouest du Yorkshire qui fut transformée en une marina. Les anciennes exploitations furent submergées et divisées par deux digues en trois grands bassins. Les terrassements permirent de former un lac avec des îles. Quelques travaux d'extraction et de remblaiement furent nécessaires pour l'aménagement des rives du lac. Le lac fut reliéà un canal voisin et un traitement paysager du site fut réalisé. Les deux autres exemples concernent la région fortement industrialisée de la Ruhr, en Allemagne. Les deux sites correspondant à d'anciennes exploitations de charbon et industries associées étaient contaminés et comportaient des ouvrages aux lourdes fondations. Les études de site et les travaux de réhabilitation de ces deux régions sont décrits.
    Notes: Abstract  Derelict land is a wasted resource and has a blighting effect on the surrounding area hence its restoration is highly desirable. Four case histories involving different aspects of dereliction and restoration are outlined. The first example considers two old colliery spoil heaps in South Yorkshire, England, which were restored, part of the site being developed for a bakery whilst the rest became a parkland. Such restoration work is essentially a large-scale exercise in earthmoving in order to achieve an acceptable contoured landform. After regrading, installation of drainage and harrowing, the spoil was treated with lime and covered with soil. Fertilizers were applied prior to seeding and planting. The next example describes an abandoned sand and gravel pit in West Yorkshire which was converted to a marina. The old workings were flooded and were separated by two berms into three large ponds. The berms were moved to form a lake with islands. Some regrading of the sides of the lake was necessary which involved cut- and -fill. Access was provided from the lake to an adjacent canal and the site was landscaped. The two remaining examples are from the heavily industrialized district of the Ruhr in Germany. Both were sites of former coal mining and associated industries and were contaminated as well as having old heavy foundation structures in the ground. The site investigations and rehabilitation of both areas are described.

    Description: Coal mining has been practised in some parts of the world, notably western Europe, for centuries and this type of mining has evolved over time as mines became deeper and larger. Today coal is worked primarily by room-and-pillar, and by longwall methods. One of the consequences of mining is subsidence, and it is associated with past and present mine workings. Indeed, old abandoned coal mines worked by the room-and-pillar method, which occur at shallow depth, often present a potential hazard as pillars collapse or voids migrate to the surface. Frequently, the situation is compounded by the fact that such workings are unrecorded. Subsidence prediction in such cases is impossible. In longwall mining, the total extraction of panels takes place, the working face being supported, while support is removed from behind the working face allowing the roof to collapse. Subsidence consequent on longwall mining can be regarded as more or less contemporaneous with mining and is normally predictable. This means that it is possible to develop an area after subsidence due to longwall mining has occurred or to incorporate features into the design of buildings and structures that will accommodate ground movements generated by subsidence. The nature of subsidence can be affected by discontinuities in the surface strata or the presence of superficial deposits. Of course, subsidence can adversely affect existing buildings and structures which do not incorporate special design features. In severe cases of subsidence damage, buildings may have to be demolished. Important buildings may be restored. Another problem associated with subsidence is flooding due to notable lowering of the ground surface. Examples of such problems and solutions are highlighted by the examples given.
