The last three decades have seen significant mining development in the northern regions of Canada, where the freeze and thaw cycle of permafrost and corresponding surface subsidence and heave represent a significant challenge at all mining stages, from the design of infrastructures to the monitoring of restored areas. Over the past ten years, SAR interferometry has been widely used to monitor g...

Abstract Mining activities generate much wastes which degenerate into various geochemical components and affect the natural composition of surface water resources. They cause Acid Mine Drainage (AMDs) influence hydrochemical evolution hydrogeological systems. This study employed parameters to characterize evaluate effects mine discharges on irrigation in mining district Enyigba, SE Nigeria. Twe...

The rapid development of deep learning cannot be achieved without the support abundant labeled data. However, obtaining such a large amount annotated data needs professionals in field synthetic aperture radar (SAR) image understanding, which leads to scarcity SAR datasets with annotations. annotations poses bottleneck performance ship detectors based on learning. Recently, semi-supervised has b...

Ground-based synthetic aperture radar (GBSAR) has the advantage of retrieving submillimeter deformation mine slope by using differential interferometry technique, which is important for safe production in mining applications. However, moving vehicle’s defocus/displaced signal will mask SAR image area affects accuracy interference phase extraction and inversion. In order to remove its influence,...

Mitigating the impact of mining activity is a significant challenge for environmental management. New approaches are required based on environmental information from in-situ, airborne and satellite observations. Airborne hyperspectral remote sensing and geophysical techniques are two such approaches being pursued at the BGS to characterise mine waste and its host rocks and then to monitor its d...

Underground reservoir technology can mitigate water shortage and pollution problems in coal mining areas has a good application prospect. While still new technology, the theory method of underground reservoirs need to be improved. This research focused on hydrochemical characteristics mine their significance for site selection reservoirs. With Shendong area as case study, major ions, toxicologi...

the cheshmeh hafez polymetal deposit is located in troud – chahshirin mountain range in southeastern damghan. in this province, the volcanism and associated mineralization are closely related to major faults anjilo and troud with nw-se trend. the exposed rocks in the study area consist of volcano clastic sequence of sandstone, tuff, volcano breccias and mostly andesitic and andesitic- basalt fl...

groundwaters hydrochemistry of ayrakan and cheshmeh shotori areas and geochemistry of rare earth elements, indicate ayrakan alkali granite as the origin of uranium and other dissolved elements in groundwaters of these areas. geochemical and hydrogeochemical studies as well as the trend of uranium and thorium transition and mobility in aqueous environments of these areas indicate uranium adsorpt...

Excessive exploitation of underground mine resources has caused serious land subsidence in China. This paper focused on monitoring and modeling the single basin coal mining area based SAR interferometry (InSAR). The optimum InSAR processing strategy to monitor was built obtain with large deformation. And a method three-dimensional mathematical measurements presented. Using Jining Coalfield (Chi...
