Abstract：With the increasing demand of coal resources, single coal seam resources decrease sharply, and multi-coal seam mining becomes more and more common. Different from single coal seam, the deformation of roadway surrounding rock caused by multi-coal seam mining is more serious and the law is more complicated. In order to study the deformation law and control technology of the surrounding rock of the main roadway under multi-coal seam mining, with Shaqu No.1 Mine in Shanxi as the engineering background, FLAC3D software was applied to analyze the deformation law of the main roadway under multi-coal seam mining from the perspective of the surrounding rock structure and rock mechanical properties, and the support scheme was designed according to the deformation law, and the three support schemes were optimized. The optimal support scheme of floor was obtained, and the pressure relief was made by grooving at the bottom corner of both sides of the main roadway. The feasibility of the design scheme was confirmed by the field monitoring results.
