WebDec 8, 2024 · The disposal of high-level radioactive waste (HLW) is one of the most challenging issues globally, and granite is considered an ideal host rock. In this paper, we present an experimental study on the transmissivity of fractured granite filled with different materials. A series of tests were carried out to study the effects of different … Webrock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. …
WebHowever, the fluid temperature evolution along the flow path and rock temperature changes was rarely considered. This study investigated flow and heat transfer characteristics of two sets of fractured granite samples each with a single fissure. The samples were collected from a geothermal reservoir of Gonghe basin in Qinghai province in China. WebGroundwater flow and the fate and transport of contaminants in fractured rock are influenced by the characteristics of the rock and thus differ from unconsolidated deposits (e.g., silt, sand, or gravel). Due to the …
WebSep 9, 2024 · To understand the seepage mechanism of fractured rocks under stress, seepage tests on fractured granite and slate specimens after triaxial compression were carried out under confining pressures from 1 to 10 MPa by using the self-developed temperature–stress–seepage coupling test system.
