-A scene independent linear transformation called – multitemporal Kauth-Thomas transformation (MKT) was implemented in this land surface change monitoring due to mining activities. 5-fold cross validation results indicated the high feasibility of using the MKT method with a computer-based hybrid unsupervised and supervised classification approach for mining monitoring.

Compared to opencut mining, underground coal mining is more common in Australia due to its lesser impact on the environment. Although there are several underground mining methods, such as the longwall, pillar, bord, and miniwall, longwall mining is the most commonly used method due to its high efficiency. However, longwall mining does lead to significant ground subsidence. Mining subsidence is ...

In this paper, we introduce a novel framework called SASA (Smart Ambient Sound Analyser) to support different ambient audio mining tasks (e.g., audio classification and location estimation). To gain comprehensive ambient sound modelling, SASA extracts a variety of acoustic features from different sound components (e.g., music, voice and background), and translates them into structured informati...

While several thousand square kilometers of land area have been subject to surface mining in the Central Appalachians, no reliable estimate exists for how much coal is produced per unit landscape disturbance. We provide this estimate using regional satellite-derived mine delineations and historical county-level coal production data for the period 1985-2005, and further relate the aerial extent ...

We apply the permanent scatterer (PS) technique to interferometric ERS SAR observations to analyse the surface subsidence induced by hard coal mining activities at the ”Prosper-Haniel” mine (Ruhr region, Germany). Underground mining causes extensive subsidence of serveral meters and typically high subsidence rates at the earth‘s surface. We show that this approach is applicable for the measurem...

PROLEGOMENA: We are in an age of intensive earth observation. Critically needed are tools that will enable efficient and accurate characterization of land surface dynamics by analyzing and extracting the spatio-temporal patterns contained in image time series. As domain scientists, rather than computational scientists, we approach the data with some ideas about what constitutes interestingness ...

industrial-scale r&d it projects depend on many sub-technologies which need to be understood and have their risks analysed before the project can begin for their success. when planning such an industrial-scale project, the list of technologies and the associations of these technologies with each other is often complex and form a network. discovery of this network of technologies is time con...

China, as the largest coal-producing and -consuming country in the world, is highly dependent on its coal industry, or “Black Gold” industry, for the national energy and economy. The consequent environmental crises, however, have persisted for decades, and the most serious effect is surface subsidence induced by underground mining. Underground coal excavation in China has ignored this problem f...

This study investigates the application of models traditionally used to estimate erosion and sediment deposition to assess the potential risk of water quality impairment resulting from metal-bearing materials related to mining and mineralization. An integrated watershed analysis using Geographic Information Systems (GIS) based tools was undertaken to examine erosion and sediment transport chara...

Southern Appalachian forests are recognized as a biodiversity hot spot of global significance, particularly for endemic aquatic salamanders and mussels. The dominant driver of land-cover and land-use change in this region is surface mining, with an ever-increasing proportion occurring as mountaintop mining with valley fill operations (MTVF). In MTVF, seams of coal are exposed using explosives, ...
