Abstract: In order to solve the technical problems that the roadway deformation with Y type ventilation was intense and the surrounding rock was difficult to control under the influences of the serious dynamic pressure, choosing track crossheading and the floor roadway of 1252(1) working face in Panyidong Coal Mine as the engineering background, based on evaluation and analysis of roadway support situation, according to the reinforcement principle contained "strengthening before mining" and "maintaining after mining" and control by stages, the bolting and jetting support technology made up of grouting anchor, bolting exterior and shelf inside support technology, pre-stressed lengthening anchor technology were used to control the deformation of surrounding rock. The effect of reinforcement was tested by numerical simulation and observation of roadway deformation. The result shows that after the mining workface crossed the second crosscut, the convergence of the roof and floor of the floor roadway and the two sidewalls is 1180 mm and 675 mm, roof subsidence, floor heave and two walls displacement volume of track crossheading was 150,780, 360 mm after gob-side entry retaining. The deformation of the gateways were effectively controlled and the channel of return air in working face with Y type ventilation was ensured to be unblocked.
