RISStudy of Gas Migration in the Fissures of Closed Goaf and CH4 Production Characteristics in Vertical Wells under Different Gas Injection Conditions
Publisher: American Society of Civil Engineers
Abstract: Gas injection displacement is a widely used technique to enhance the recovery of coal methane (CH4) or oil reservoirs. Additionally, this method plays a crucial role in effectively developing CH4 resources in a closed goaf. ...
Low Cycle Fatigue Properties of Corroded Q355B Steel
Publisher: ASCE
Abstract: The low cycle fatigue properties of Q355B structural steel subjected to different levels of corrosion were investigated in the present study. The corroded Q355B steel coupons were obtained by means of cyclic wet–dry immersion ...
Multifactor Evolution and Carbon Sequestration Effect of Coal Pore Structure during CO2 Storage in a Coal Mine Goaf Environment
Publisher: American Society of Civil Engineers
Abstract: Excessive greenhouse gas emissions, primarily CO2, are a principal cause of global warming. China’s extensive abandoned mines and goafs present a unique opportunity for CO2 storage, offering a dual benefit of reducing ...
