This study conducted a seepage experiment of broken shale under cyclic loading and unloading conditions to investigate the permeability characteristics with different particle sizes stress disturbance. There were six groups samples sizes, three cycles test shale. The influence number size on damage was analyzed. Furthermore, stress-seepage model established analyze variation sensitivity stages. results show that initial permeability, damage, are negatively correlated first cycle has...
In this study, four types of coal samples (complete, parallel fracture, vertical and inclined fracture) were prepared, mining stress paths designed. Cyclic loading–unloading seepage tests conducted on to study the evolution characteristics. Evolution characteristics permeability porosity investigated. The cycle factor was introduced research effect number permeability. Stress sensitivity coefficients obtained by fitting curves. relationship between analyzed. Results indicate that enhancement...
The permeability evolution characteristics of fractured rock mass under complex stress environment is a key problem to explore the migration law shale gas in unconventional reservoirs. Therefore, this study used loaded body injection displacement test system determine carbonaceous during cyclic loading. experimental results were establish seepage model and structure repeated loads analyzed. show that:(a)the loading negatively correlated with effective stress, decreases stage recovers...
