Abstract: In order to solve the problems of large abutment pressure of coal pillar and difficult treatment of coal pillar rock burst in thick seam with mine pressure b umping in potential in deep mine, a trial on the layout of the vertical completed pillarless gateway driving along goaf was conducted in No. 1411 coal mining face of Huaf eng Mine.High deformation and high mine pressure bumping of the mine gateway caused by the gateway driving along goaf with a narrow coal pillar between No.1410 d own gateway and No. 1411 upper gateway were treated and controlled.The mine pressure and microseism observed data showed that the deformation of the roof-to-floo r was reduced by 131.5 mm, the mine seismic grade, released energy ad releases numbers were obviously reduced, the mine seismic over 0.8 grade were reduced by 87% and the released energy was reduced by 96%.
