Permeability evolution during progressive deformation of intact coal and implications for instability in underground coal seams
We report measurements of deformation, strength and permeability evolution during triaxial compression of initially intact coals. Permeability is continuously measured by the constant pressure differential method, together with axial and volumetric strains for both water (H2O) and strongly adsorbing carbon dioxide (CO2) gas. Strength and Young’s modulus increase with increasing confining stress...
متن کاملSemiotic Seams: Fractal Dynamics of Re-entry
This essay concerns fractal geometry as a bridge between the imaginary and the real, mind and matter, conscious and unconscious. The logic rests upon Jung’s theory of number as the most primitive archetype of order for linking observers with the observed. Whereas Jung focused upon natural numbers as the foundation for order that is already conscious, I offer fractal geometry, with its endlessly...
متن کاملLithotype Characteristics and Variation in Selected Coal Seams of the Gates Fqrmatioin, Northeastern British Columbia
A combined field and laboratory investigation of selected coals within the Gates Formation in the Rocky Mountain foothills. northeastern British Columbia, was undertaken during the summer of 1988. and continued in 1989. with the purpose of gaining a better understanding of the sedimentological factors controlling variations in coal cc~mposition. This project involves examination of both the or...
متن کاملSource and Distribution of Phosphorus in British Columbia Coal Seams
Phosphorus contents of coal from around the world vary although there is a tendency for Permian coals from India and Australia, and Cretaceous coals from Western Canada to have more phosphorus than Carbcmiferous coals from Europ+ and USA (Table 1). This may be because of the evolution of vegetation type over geological time or because of the conditions in the coal swamps. Data presented here su...
متن کاملPyrite Occurrences in Telkwa and Quinsam Coal Seams
Sulphur in coil1 is il major environmental concern. The use of coal for combustion requires the control of sulphur dioxide emissions. To reduce these emissions, the total solphur content in c~ial product ~must he decreased. This can he accomplished by using low-sulphur coal. cleaning coal prior to combustion. retaining sulphw during wmhustion. or hy treatment of tlur gases after combustion. The...
