Effect of nitric acid on the pore structure and fractal characteristics of coal based on the low-temperature nitrogen adsorption method
TL;DR: In this paper, the pore structure and fractal characteristics of acid-treated coal were analyzed using the low-temperature nitrogen adsorption method, scanning electron microscopy and the fractal theory.
Journal ArticleDOI
Effect of particle size and adsorption equilibrium time on pore structure characterization in low pressure N2 adsorption of coal: An experimental study
TL;DR: In this article, the influence of particle sizes and adsorption equilibrium time (AET) on pore structure characterization using low pressure N2 adaption (LPGA-N2) method was examined.
Journal ArticleDOI
Evolution of pore and fracture of coal under heating–freezing effects: An experimental study
TL;DR: In this article, a tube furnace was used to heat coal samples to 100 and 300°C and liquid nitrogen was applied to freeze the heated coal sample to explore the evolution of coal pore structures.
Journal ArticleDOI
Application of gas wettability alteration to improve methane drainage performance: A case study
TL;DR: In this article, the fluorocarbon surfactants perfluorooctyl methacrylate monomer-containing polymethacrylated (PMP) was used to alter the wettability of coal seam to strong gas-wetness during the hydraulic fracturing process.
Journal ArticleDOI
Role of coal deformation energy in coal and gas outburst: A review
TL;DR: In this paper , a spatiotemporal evolution model of the release of coal and gas outbursts was proposed, and a new energy release model was established to discuss the role of coal deformation energy in actual outburst.
