Abstract

Abstract

Taking the simulation of indigenous coal and tectonically deformed coal in Pingdingshan coal district as the research object, porosity and permeability of different coal samples under different factors are determined in this paper. The variation trend of porosity and permeability under different factors is analyzed. The experimental results show that four factors analyzed have significant impact on both porosity and permeability of coal. The effect of confining pressure is greater than temperature when confining pressure and temperature work together. And part of experiment data are fitted by the Origin software, concluding with the function relationship of porosity and permeability of coal.
- porosity,
- permeability,
- confining pressure,
- temperature,
- moisture,
- tectonically deformed coal
