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 کاملSpecialties of Coal Seams Mining under Conditions of Western Donbas
Nowadays, one of the main tasks of Ukrainian coal industry is increasing labour productivity by means of complex mechanization and automatization of mining operations with usage of modern equipment. The best example is implementation of modern plow complexes on Western Donbas mines, PJSC “DTEK Pavlogradvugillia”. Currently, plowing is one of perspective directions of coal extraction development...
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...
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 کاملEstimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine
Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' safety. The purpose of this work is to provide the prediction maps for the C1, C2, and B2...
