Experimental investigation on the seepage law of pressure-relieved gas under the influence of mining
The stress distribution characteristics of the coal seam floor and the variation of pressure-relieved gas seepage velocity along with working face being advanced are studied experimentally. According to experimental data, the distribution rule and the influence area of abutment pressure of gob floor are analyzed. The scope of three zones formed by gas seepage velocity along lateral direction above the gob is determined, and the coupling rule of pressurerelieved gas is summarized. The above results provide a technical support for the spot gas extraction.
