Abstract 94702 mechanized mining face of Xuecun Mine was thin automated face, whose outer segment stoping had to go through X6 collapse column. According to the X6 collapse column hydrographic evaluation, anti-conducting water subsided column was decided. Therefore, during collapse column mining face pushing, reasonable mining method was conducted, which resulted in passing the collapse column associated fault influence extents, saving reopening the cutting-hole roadway and the second move preparation of the project and accumulating mine stoping experience and methods in similar geological structure.
