No. 10 coal seam mined in Mugua Mine, the upper part was the No. 9 coal seam goaf, the coal seam spacing was very close, and due to the complicated geological conditions, the 10-102 working transport was seriously deformed around the surrounding rock. In order to solve this problem, through the theoretical research and numerical simulation method, the support system was optimized for the rework section. Field application and surrounding rock displacement observation confirmed that when the working face was advanced to this position, the maximum subsidence of the roof of the roadway was about 100 mm, the maximum displacement of the two sides about 180 mm, and the overall deformation of the roadway was small, and the control within a reasonable range, the technology achieved good support and met the requirements of coal transportation, with a good support effect.
