Abstract: In order to research the gas control problem of the area in the coal lane stripes of the single serious outburst coal with unprotected conditions of the deep mining, the surrounding rock stress distribution characteristics were analyzed by using FLAC^3D, and the reasonable space position of roadway during draining coal seam gas by using through bed holes in the coal bottom roadway is studied. Results show that the pre-excavating unloading floor lane arranged the position under the undetermined groove and with the length of normal of 8 to 15m is reasonable and feasible. Both the drilling gas flow rate and the coefficient of permeability in the both sides of the 15 m range seam are increased in varying degrees, as the 213 floor lane located the position of the average offset 9 m under the undetermined groove in the Qujiang Coal Mine of Fengcheng Mining Area. It shortens the extraction time, effectively reduces the danger of coal and gas outburst. At the same time, it can save a lot of drilling engineering, reduce cost, relieve the tense situation of mining by using the drilling borehole cross the seam with adopting the non equidistance arrangement form.
