Book Description
Quarrying and all other branches of surface mining rather than diminishing in importance have become of more and more consequence economically, industrially and particularly with the depletion of high-grade deep-mined mineral reserves. Low-grade minerals require low cost extraction and this in many cases necessitates very expensive mechanized equipment with the cost of individual units running into millions of pounds in the case of large scale operations with high productivity. There has been, and there still is, a tendency for the smaller single quarries to be amalgamated into groups with large financial resources and therefore with the ability to purchase these expensive machines so necessary to make operations viable. This in turn requires wider administrative and technical knowledge in executives of these groups and as these often handle a wide range of products from widely differing systems of working, this technical knowledge should embrace the exploitation of many different types of deposits. There is, at present, a great dearth throughout the world of such qualified executives as is apparent from advertisements of vacancies in the technical press. It would appear that these industries offer an attractive career to the widely qualified and experienced technologist in these fields. This book deals with methods of working in the surface extractive indus tries, quarry management and power supply-but does not deal with related ancillary processes except where these affect quarrying operations.

Book Description
KWIC Index of Rock Mechanics Literature, Part 2: 1969-1976 is an index of subjects in rock mechanics. The KWIC (keyword-in-context) index is produced by cyclic permutation of significant words in the title of the publication. The text covers materials in rock mechanics and geomechanics published around the 70s. The book will be of great use to students, researchers, and practitioners of geological sciences.

Book Description
Supergene and Surficial Ore Deposits; Textures and Fabrics is a collection of papers that deals with economic geological deposits, particularly as endogenic type, or as an integral part of their geological environment. One paper explores the possibility that the evolution of ores of sedimentary affiliation or of sedimentary rocks and their chemistry during geologic history can be a product of the evolution of the outer spheres of the earth combined with a cycling phenomena that proceeds in a spiral way. Another paper discusses the role of climate on a large range of depositional environments through mobilization, both by chemical and physical events, of metal-ions. Mobilization can also occur by controlled deposition and enrichment of the "mobilized" ions in a certain sedimentary environment. Various depositions occur in different climates, for example, bauxites, requiring higher precipitation levels, form in humid zones. One paper points that ore-mineral accumulations controlled by descending supergene solutions play a significant role in ore-mineral depositions. The collection is beneficial to geologists, industrial chemists, researchers, technical designers, and engineers whose works are related with ore deposits and mining.

Book Description
Winner of the 2007 E.B. Burwell, Jr. Award of the Geological Society of America Mining activity has left a legacy of hazards to the environment, such as waste, unstable ground and contamination, which can be problematic when redeveloping land. This book highlights the effects of past mining and provides information on the types of problems it may cause in both urban and rural areas. By way of example, the book also demonstrates how such problems may be anticipated, investigated, predicted, prevented and controlled. Furthermore, it shows how sites already affected by mining problems and hazards can be remediated and rehabilitated. Covering subsidence, surface mining, disposal of waste, problems resulting from mine closure and mineral processing, Mining and its Impact on the Environment is an excellent reference for practising mining and geotechnical engineers, as well as students in this field.
