This chapter reviews methods of coal extraction, with a focus on advances in technology. The two main methods of coal mining – underground and surface mining – are first described. The following sections cover advances in coal mining machinery and systems, with extensive discussion of the role of .
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of ...
Sep 01, 1996· Microbial mining of copper sulphide ores, has been practiced on an industrial scale since the late 1950s. Since then, advances in microbial mining and the role of microorganisms involved in solubilization of metals have assumed commerical importance.
Jun 13, 2012· Coal is one of the cheapest and most reliable sources of energy, and as demand soars new technology will be crucial. With global demand for coal widely expected to rise over the next 20 years, Dr Gareth Evans finds out how a range of new technologies will help the coal mining industry meet that need from both existing and less conventional sources.
Recent advances in genome sequencing and techniques in genetic manipulation have enabled researchers to study the biosynthetic genes of these SMs. Aspergillus terreus is the wellknown producer of lovastatin, a cholesterollowering drug. This fungus also produces other SMs, including acetylaranotin, butyrolactones, and territram, with ...
