The Boulby Dark Matter Collaboration (BDMC) is running several experiments for particle (WIMP) dark matter search in the Underground Boulby Laboratory. These include a liquid xenon detector (ZEPLIN I) and a low pressure gas TPC with directional sensitivity (DRIFT I). Next stage double-phase xenon detectors ZEPLIN II and ZEPLIN III, and a new TPC DRIFT II will be installed at Boulby in a few mon...

Article describes the issues related to the impact of underground mining exploitation on pipelines in Poland. For this purpose there was conducted the impact analysis of horizontal strains, curvatures and tilt changes of the surface on loads and displacements of these objects. Ground deformations can cause pipelines failures and thereby reduce their reliability. In addition, the examples of typ...

Underground caverns in rock salt deposits are the most secure disposal method and a type of gas-storing facility. Gas storage plays a vital role in ensuring that a strategic relationship is secured between an established energy infrastructure provider and a midstream energy company. The Fischells Brook area is a pillow-shaped body of salts located in the St. George's Bay area of southwest Newfo...

Ensuring the stability and integrity of underground gas storage salt caverns is a very complicated subject due to the non-linear and time-dependent behavior of rock salts under complicated thermal and mechanical loading conditions. For this reason, pressure and temperature fluctuations in the caverns and their surrounding strata must be integrated into the analysis and the numerical tools that ...

To lower stability requirement of gas production in UCG (underground coal gasification), create better space and opportunities of development for UCG, an emerging sunrise industry, in its initial stage, and reduce the emission of blast furnace gas, converter gas, and coke oven gas, this paper, for the first time, puts forward a new mode of utilization of multiple gas sources mainly including gr...

Herein, we report on the results of solventand sorbent-free HS-GC-MS (headspace – gas chromatography – mass spectrometry) analysis of the headspace volatiles (HSVs) of fruits of cultivated melon (Cucumis melo L. cultivar “ananas dinja” [pineapple melon]) and pear (Pyrus communis L. cultivar “Julska lepotica” [the beauty of July]), as well as of underground parts of carrot (Daucus carota L. cult...

This study was designed to monitor molinate losses in surface and underground waters during Ordram application in a rice field situated in central Portugal. Water samples were collected from different sites, before, during and about one month and a half after Ordram application. Molinate quantification was based on a solid-phase microextraction (SPME) method followed by gas chromatography with ...
