Carbon dioxide (CO2) sequestration is considered to be one of the most effective technologies mitigating greenhouse gas emissions. In this technology, single phase supercritical CO2 injected into an underground geological formation such as a deep saline aquifer. Existing projects demonstrate that successful implementations are possible; however, significant uncertainties associated with risks l...

Environmental problems have attracted worldwide attention, and the recognition of their importance has risen through the newspapers and other media every day. In the construction industry, industrial waste resulting from civil engineering work has become a big problem, termed construction pollution. Construction sludge and muddy water resulting from construction or demolition are particularly d...

The goal of this paper is to give a mathematical model describing the global behavior of an underground waste repository, once the containers start to leak. The purpose of such a global model is to be used for the full field simulations used in safety assessements. The physical situation can be described as an array made of high number of leaking modules inside a thin low permeable layer (e.g. ...

The Industrial Revolution has led to a substantial i ncrease in the generation and release of greenhouse gases (GHG) into environment. These GHGs like CO2 if present in abundance in the atmosphere cause damage to the natural ecosystems through global warming. One of the possible approaches to mitigate the global warming phenomena is by safely and long-term underground disposal of CO2 in suitabl...

Due to the constantly deteriorating environmental situation in regions with mining enterprises, article considers topical issue of disposing maximum possible volume waste from and processing low-grade ferrous ores through creation an effective underground geotechnology. Traditional procedure descending reserves a caving system does not allow be disposed gob. The idea is use geotechnology based ...

As the utilization range of smart devices for infrastructure has widen its application owing to flourishing of smart devices, studies on the technologies to graft IT onto underground utilities are actively carried out. In particular, as underground utilities have a characteristic of invisibility, studies on a management system converged with augmented reality are demanded for the efficient mana...

Understanding the effect of underground excavations and barrier capability near field are relevant to geologic disposal nuclear waste. For a repository in crystalline host rock characterization naturally fractured excavated disturbed zone importance study migration radionuclides. Excavations could weaken components that part engineered system. Permeable zones also develop around walls create co...

The current brief review paper on rock stress measurement methods is very crucial factors in mining, civil infrastructure, geothermal energy, nuclear underground disposal, large oil storage caverns, etc as well geology and geophysical area. Measurement of situ a challenging difficult quantity not possible to measure directly. Measure the deformation or displacements hydraulic by perturbing conv...

Research activities in safety regulation of radioactive waste management are presented. Major activities are as follows. As for the geological disposal, major research areas are, developing “safety indicators” to judge the adequacy of site investigation results presented by an implementer (NUMO), compiling basic requirements of safety design and safety assessment needed to make a safety review ...
