In view of the problem that the working face was in the shape of " knife handle " and the difficulty of mining was affected by faults and other conditions, No. 11215 gangue filling working face of Xingdong Mine was taken as an example, and takes measures such as modifying the filling body to increase strength and reduce mining stress transfer, adding cement and roller compacted concrete to increase the strength of the filling body, timely rowing of wood cribs and filling gangue and cement slurry after removing the frame, and retaining the roadway along the filling roadway. The application results showed that the deformation of surrounding rock was within the allowable range, which did not affect the normal use of roadway. The reserved 20 m coal pillars were all recovered, which increased the service life of the mine. By using the design and development of the removal platform with multiple sets of winch relay, the 10.5 m super long gangue filling support was moved as a whole. The process realized the rapid moving of the working face, alleviated the tension of mining replacement, and provided a reliable basis for the overall moving of the similar mine working face along the filling and retaining roadway support, which had good economic and social benefits.
