Experiments Study on the Briquette Permeability with Temperature and Effective Stress Change

To study the impact law of temperatures and effective stresses on briquette permeability,self-made permeability experiment instrument was taken to do permeability experiments under different temperatures and effective stresses conditions.According to the experiment database figures,when temperature is constant,briquette permeability will decrease with effective stress increasing;when effective stress is constant,briquette permeability will decrease with temperature increasing.By fitting the experiment database,the relationship between briquette permeability and temperature and effective stress was showed exponential function change law.Therefore,the impact of temperature and effective stress on briquette permeability should be considered comprehensively in real practice.
