A history of Maamba coal mine and its socio-economic impact on Zambia, 1968-2010.
This study examines the origins and development of Maamba Coal Mine and its socio-economic impact on Zambia. It demonstrates that although Ian Smith’s Unilateral Declaration of Independence (U.D.I) in Rhodesia, 1965 was the key driver in the development of commercial mining of coal in the country, …

Managing the acidity of abandoned water filled coal mining voids in Collie (Western Australia) using organic matter
… organic matter additions to increase pH in abandoned water filled coal mining voids in Collie was investigated. Previous studies have demonstrated that passing acidic drainage through organic matter increased the waters pH. Laboratory trials using intact sediment cores (collected from …

Detection of collapses and communicating with inaccessible areas in underground coal mines using WSN
… sensor networks (WSN) are used in underground mines to monitor concentration of gases, temperature, and humidity. A WSN deployed in underground mines can also be used for localisation of miners and for detecting collapses. Underground coal mines consist of long and narrow tunnels, several …
