Differential SAR Interferometry (D-InSAR) is an effective tool in monitoring land subsidence because of its greater coverage area and better resolution of height change. A series of Japanese Earth Resources Satallite-1 (JERS-1) images from 1992 to 1998 has been used in monitoring the mine subsidence in the test site of this study, one of the important coal mining areas in China. D-InSAR procedu...

The problem of mined area reduction is addressed in this paper. Pieces of information collected using airborne multispectral scanners and airborne full polarimetric SAR, together with context information, all integrated in a geographical information system, are classified and combined in order to find indicators of mine presence and mine absence and provide image analysts with adequate tools to...

'Ferroplasma acidarmanus' strain Fer1 is an extremely acidophilic archaeon involved in the genesis of acid mine drainage, and was isolated from copper-contaminated mine solutions at Iron Mountain, CA, USA. Here, the initial proteomic and molecular investigation of Cu(2+) resistance in this archaeon is presented. Analysis of Cu(2+) toxicity via batch growth experiments and inhibition of oxygen u...

Explosive growth in the size of spatial databases has highlighted the need for spatial data mining techniques to mine the interesting but implicit spatial patterns within these large databases. This thesis deals with reducing the computational complexity of the exact and approximate spatial autoregression (SAR) model solutions. Estimation of the parameters of the SAR model using Maximum Likelih...

We sequenced and annotated the complete 7,170,504-bp genome of a novel secondary metabolite-producingStreptomycesstrain,Streptomyces albusSM254, isolated from copper-rich subsurface fluids at ~220-m depth within the Soudan Iron Mine (Soudan, MN, USA).

The article describes the development and application of a new discrete time-event simulation modeling methodology used in the copper mining industry in Chile. The proposed methodology creates a simulation model that represents a mine-mill operation, and it is used to evaluate different improvement options to maximize the system performance. Two applications of this methodology to existing copp...

cheshmeh-konan area is located ~15 km northwest of tasuj, east-azarbaidjan province. the most important lithologic units of the area are red sandstones, green-gray sandstones, shale, and marl (miocene). based on field evidence and petrographical investigations, the host sediments were deposited in a peritidal setting associated with a sabkha-type environment. copper mineralization in the area o...

Although bioleaching was used unknowingly by the ancients to extract metals (principally copper) from ores, the development of modern commercial bioleaching processes is relatively new. It began in the late 1940s, with the discovery of the role of bacteria in the formation of acid mine drainage. From there, research and development activities in the field flourished, and the earliest commercial...
