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...

The cryostats of the ATLAS LAr calorimeter system are installed in the ATLAS cavern since several years. Following this, an effort to install and commission the front-end and back-end read-out electronics as well as the timing, trigger and control electronics (infrastructure, crates, and boards) has been ongoing and is finished now, in time for the cavern closure. Following cautious procedures ...

Rectangular caverns are increasingly used in underground engineering projects, the failure mechanism of rectangular cavern wall rock is significantly different as a result of the cross-sectional shape and variations in wall stress distributions. However, the conventional computational method always results in a long-winded computational process and multiple displacement solutions of internal re...

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 ...

The simultaneous occurrence of subcutaneous emphysema and intravascular air due to an air embolism is a rare condition. Here, we report a patient with COPD who developed a severe episode of hemoptysis due to rupture of a previously undiagnosed lung cavern. Intubation and ventilation led to the development of both massive subcutaneous emphysema and a massive air embolism, resulting from aspirati...

It is of great significance to study the mechanical properties rock fracture for stability engineering projects. The properties, including normal compression and shear fracture, are studied by a series tests considering effect lateral stress using self-developed true triaxial test apparatus. results show that initial stiffness maximum closure value increase with stress, peak strength dilatancy ...

Anthropogenic effects on climate can be mitigated through various measures, among them being CO2 sequestration in geological media. Geological sinks for CO2 do not need any major new technological development; the technology exists and has been applied for other uses. The challenge is rather to identify the most appropriate methods and sites for long-term sequestration. There are several potent...

We present an accurate model of the muon-induced background in the DAMA/LIBRA experiment. Our work challenges proposed mechanisms which seek to explain the observed DAMA signal modulation with muon-induced backgrounds. Muon generation and transport are performed using the MUSIC/MUSUN code, and subsequent interactions in the vicinity of the DAMA detector cavern are simulated with Geant4. We esti...
