In this paper, through study on several commonly used programs cuting through the faults, according to the principles of cutting through faults finely, and combining with the changes of factual geological condtions of working section, comprehensive technolgies for cutting through faults are carried out in No.4305 comprehensive mining section, they are "controlling angles along pseudo-faults—optimizing mechanical rock breaking technology—rock breaking and blasting machines combination". According to changes in the F40502 fault section, relative countermeasures have been carried out to ensure the recovery rate, reduce the loss of coal resources, effectively control the accident rate of the equipment, and ensure safe production.
