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. ...
Experimental Study of Influencing Factors on Mechanical Properties for New Coal-Like Materials
Publisher: ASCE
Abstract: Physical similarity simulation is one of the best methods for improving coal bed methane extraction efficiency, and the development of reasonable materials is important for improving physical similarity simulation testing ...
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 ...
Crack Propagation and Material Characteristics of Rocklike Specimens Subject to Different Loading Rates
Publisher: American Society of Civil Engineers
Abstract: This paper evaluates the cracking mechanism and material characteristics of rocklike specimens under five loading rates (0.02, 0.06, 0.10, 0.14, and 0.18 mm/s). The rocklike cylinder specimens were prepared and mixed using ...
