RESEARCH ON THE MICROCOSMIC MECHANISM OF COAL-GAS OUTBURST
In order to obtain the mechanism of the coal-gas outburst, the quantum theory is applied to study the mutual absorption between the coal and the methane molecule. The absorption is a physical process, with an energy of 1.16KJ/mol, which can be obtained by the density functional theory. The damage of the rock results from the influence of mining stress and the subsequent changes around the mining face, which produces electromagnetic waves with a wide frequency range. The intergrowth system, which is generated by the absorption, changes from a ground state to an excited state after it absorbs the electromagnetic wave energy. Then, the methane molecule changes from an absorption state to a free state and a large number of molecules escape from the coal pores increasing the pressure. As a result, the coal-gas outburst is more likely occur at the flimsy location.
