Leaky faults provide important flow paths for fluids to move underground. It is often necessary to characterize such faults in engineering projects such as deep well injection of waste liquids, underground natural gas storage, and radioactive waste isolation. To provide this characterization, analytical solutions are presented for groundwater flow through saturated aquifer-fault-aquifer systems...

Pulse radar systems, known as subsurface interface radars, have been widely used to locate underground objects. Three-dimensional towershaped antennas were developed to replace conventional plane antennas and accurately detect the location and depth of underground objects like gas pipes, water pipes and transmission cables. The newly developed radar system using these tower-shaped antennas is c...

today, saving and storing water are among the most critical and important issues which have attracted the world's attention. history of storing water in the form of ghanat and water reservoir by iranians goes back to ancient times. studies on this field show that benefiting from underground dams was one of the methods employed for exploiting water in past times. in countries like iran, due...

The article presents a method of forecasting the deformation land surface over large fields underground gas storage facilities located in salt caverns. solution allows for taking into account many parameters characterising operation facilities, such as cavern processes (leaching, enlargement, operational, etc.), their depth, distribution, diameter, shape, and others. advantage applied other ava...

The Giant Mine, located in Yellowknife, Northwest Territories, Canada has been operating as a gold mine since 1948. Giant has been primarily an underground operation which used roaster technology to remove of gold from refractory arsenopyrite ore. The roasting process produced arsenic trioxide bearing dust as a waste product. This dust was pneumatically conveyed into underground storage chamber...

Energy security is a multidimensional and multifaceted concept, therefore defining it complex problem. It requires the consideration of wide set factors from fields economics, geology, ecology geopolitics, all which have an influence on energy or lack thereof. The article focuses natural gas, very specific fuel in European context. most “politicized” source energy, as consequence its growing im...
