Journal ArticleDOI
Experimental investigation on coal pore and fracture characteristics based on fractal theory
TL;DR: In this article, the fractal curves of the pores and fractures in coal samples with different particle sizes determined from MIP were all divided into two parts by an inflection point.
Journal ArticleDOI
Effect of moisture on the desorption and unsteady-state diffusion properties of gas in low-rank coal
Haijun Guo,Liang Yuan,Yuanping Cheng,Kai Wang,Kai Wang,Chao Xu,Aitao Zhou,Jie Zang,Jiajia Liu +8 more
TL;DR: In this paper, a new water injection device was designed to prepare coal samples with a variety of moisture contents, and a novel method to measure the gas desorption properties in coal containing water was introduced.
Journal ArticleDOI
Square-form structure failure model of mining-affected hard rock strata: theoretical derivation, application and verification
TL;DR: In this article, the failure model of coal-bearing strata was derived theoretically, which was applied to calculate the failure laws of the thick-hard igneous sill, and then, the model was verified by the methods of numerical simulations and surface subsidence measurements.
Journal ArticleDOI
Damage evolution analysis and gas–solid coupling model for coal containing gas
TL;DR: In this article, the authors derived an expression for the damage factor of coal containing gas based on the theory of energy conservation to monitor the evolution law of the damage factors during the entire stress-strain process.
Journal ArticleDOI
Coal permeability evolution characteristics: Analysis under different loading conditions
TL;DR: In this article, coal specimens reconstituted by coal powder with different particle sizes were investigated and their permeability under loading conditions was found to be completely different under constant hydrostatic pressure conditions.
