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 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...

In order to improve the availability of solar energy, this paper introduces a new solar energy storage device and its parameters automatic measuring system. The device puts the heat which was gathered by synchronous tracking solar collector into underground concrete storage pile. Meanwhile, the system could simultaneously measure the temperature, pressure and flow of the device, etc. Some deriv...

The KLOTZ Club is a multi-national group of explosives safety specialists concerned with the safe storage of military ammunition and munitions. One topic of present interest to the KLOTZ Club is the effects of the hazardous environment that would result from an accidental explosion in an underground military munitions storage facility. The necessary placement and/or design of nearby above-groun...

Abstract Large-scale underground storage of hydrogen gas is expected to play a key role in the energy transition and near future renewable systems. Despite this potential, experience remains limited. This work critically reviews most important elements crucial technology, including properties their significance for subsurface operations, sources historical set state art. The cyclical nature ope...

Studies were carried out on the localization and mapping of gas stations in the urban area of São Carlos city, for an environmental diagnosis related to soil, surface water and underground water contamination resulting from likely leaking in fuel underground storage tanks. Considering that a provision of legal restriction makes it possible that most of public areas are not located in gas statio...

given the potential for carbon storage in plant tissues, this approach has a serious interest in recent decades. therefore, the ability of carbon storage in astragalus gossypinus and astragalus parrowianus were examined in part of alpine pastures in kermanshah province. after determining the representative districts, according to 4 main aspect and 5 category elevation was determined representat...
