Study on Influence of Sur-electromagnetic Field to Gas Flow of Coal-body
On the basis of the condition of the problem being existed of methane exploitation and utilization and gas drainage of our country at present, the change rule of adsorption and desorption of coal in electromagnetic field-Electromagnetic Modification(EM), the change of micro structure of coal during electromagnetic modification through infrared spectrum are discussed. Further the microscopic mechanism of adsorption and desorption and EM are analyzed. By studying and utilizing the rule of adsorption and desorption of coal in electromagnetic field-EM and exerting the different frequency or voltage electromagnetic field outside to enhances the permeability, the flow and drainage percentage of the gas, and its application in gas drainage and gas controlling aspects are studied.Through researching the change rule of surface electromagnetism modification to gas adsorptive capacity and its influence to gas storage and transport of the coal-body, and the value simulation of the gas mobile influence in sur-electromagnetic field, the influence to the permeability, flow and drainage percentage of the gas in different frequency and voltage electromagnetic field are studied. And also the reason of change of gas adsorption under the electromagnetic field function is analyzed from the surface and internal microscopic structure of coal. Thus enhances gas drainage effect of the coal -bed. It have important practice and the application value in controlling gas accident effectively and reducing coal and gas outburst occurring in coal mine.
