Deformation of Coal Induced by Methane Adsorption at Geological Conditions
The quenched solid density functional theory (QSDFT) is employed to study methane adsorption on coal at geological conditions. Themain focus is made on coal deformation in the course of adsorption that may result in either expansion/swelling or contraction, depending upon the pressure, temperature, and pore size. Twoqualitatively different types of deformation behaviorwere found depending upon ...
متن کاملStudy of Gas Environment Impacts on Volumetric Coal Matrix Changes
The Outburst can be defined as a sudden release of coal and rock accompanied by large quantities of gas into the underground coal mine workings which represents a major hazard in underground coal mines. Gas drainage has been proven to be successful in reducing outburst hazards by decreasing the in-situ gas pressure. One of aspect of gas drainage from coal seams is coal matrix volume changes. Cu...
متن کاملNumerical Simulation Study on Coal Bed Methane Development
In order to find out the advantages and disadvantages of various development methods of coal bed gas, the experimental block provided by the field is studied, the component calculation model is established by CMG numerical simulation software on the basis of fine geologic modeling. Four development schemes are designed which are depleted development, development of hydraulic fracturing, develop...
