Numerical simulation of flooding induced uplift for abandoned coal mines: simulation schemes and parameter sensitivity

نویسندگان

چکیده

Abstract Numerical simulation approaches have been widely applied to study mining induced subsidence, and they are potential methods the flooding uplift for abandoned mines. This paper gives an overview about different numerical simulate by underground mines, including three hydraulic conditions, considering both unconfined confined water conditions. Four basic schemes using 1-dimensional rock column models verified analytical solutions demonstrate these procedures. The results reveal that is mainly related pore pressure in mine goaf. parameter documents height stiffness of goaf strongest influence on maximum surface uplift.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Strength Reduction of Coal Pillar after CO2 Sequestration in Abandoned Coal Mines

CO2 geosequestration is currently considered to be the most effective and economical method to dispose of artificial greenhouse gases. There are a large number of coal mines that will be scrapped, and some of them are located in deep formations in China. CO2 storage in abandoned coal mines will be a potential option for greenhouse gas disposal. However, CO2 trapping in deep coal pillars would i...
