Estimation 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...
متن کاملPermeability 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 کاملInstability leading to coal bumps and nonlinear evolutionary mechanisms for a coal-pillar-and-roof system
This paper studies the unstable mechanisms of the mechanical system that is composed of the stiff hosts (roof and floor) and the coal pillar using catastrophe theory. It is assumed that the roof is an elastic beam and the coal pillar is a strain-softening medium which can be described by the Weibull s distribution theory of strength. It is found that the instability leading to coal bump depends...
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 کاملIntelligent prediction of heating value of coal
The gross calorific value (GCV) or heating value of a sample of fuel is one of the important properties which defines the energy of the fuel. Many researchers have proposed empirical formulas for estimating GCV value of coal. There are some known methods like Bomb Calorimeter for determining the GCV in the laboratory. But these methods are cumbersome, costly and time consuming. In this paper, m...
