Abstract: At present, most coal mining faces have fault problems. In view of the concrete geological occurrence conditions and
fault conditions of 48705 working face in Ximing Coal Mine, this paper determined that the method of overhanging, underhanging
and blasting was used to cross the fault in the working face, determined the specific construction procedure and blasting
parameters, and chose the appropriate method for roof support when crossing the fault. Finally, it put forward the safety technical
measures when crossing fault in working face.

 Key words: crossing faults; construction procedure; blasting parameters; roof support
