The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of ... 詳細を見る

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to ... 詳細を見る

Soil’s electromagnetic properties adversely affect the performance of electromagnetic induction (EMI) sensors and if conditions are severe enough, render them useless. A simple circuit model is often used to express the electromagnetic induction response of a target analytically. This ... 詳細を見る

There are only two types of naturally-occurring earthquakes anywhere on the Earth: 1) those associated with the dynamics of plate tectonics and 2) those associated with the dynamics of the hydrologic cycle. The first type is characteristic of an INTERplate setting (like the San Andreas ... 詳細を見る

Geothermal systems represent a large resource that can provide, with a reasonable investment, a very high and cost-effective power generating capacity. Despite its unquestionable potential, geothermal exploitation has long been perceived as limited, mainly because of the dependence from ... 詳細を見る

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user ... 詳細を見る

Injection of 3-D hot plume blob develops localized and short-term increases in slab surface temperatures, consistent with the Abukuma adakite, Northeast Japan. 3-D mantle flow develops trough of the lowered slab surface temperatures implying along lowered slab surface temperatures, ... 詳細を見る

The Solargeotherm project is assessing the possibility of using vertical geothermal probes drilled into a rock mass (bedrock) for storing the thermal energy produced by solar panels and later releasing it. The research project relies on the installation of an experimental system and the ... 詳細を見る

Poroelasticity equations describe the interaction between fluid flow and solids deformation within a porous medium. Modeling of poroelasticity is coupling between elastic deformation of porous materials and Darcy’s law. Poroelasticity has numerous real world applications such as in ... 詳細を見る

Introduction: This study presents the 3D electromagnetic model in layered media using induction logging tool. This algorithm utilizes electromagnetic wave frequency domain (EWFD) interface of Maxwell equations. Electromagnetic methods are popular tools for the measurement of resistivity ... 詳細を見る
