Coal face fault rock mass crushing method based on directional drilling technology

The invention discloses a coal face fault rock mass crushing method based on a directional drilling technology. The coal face fault rock mass crushing method comprises the steps of determining a coal face fault passing path, determining a directional drilling path, performing directional drilling field tunneling, performing directional drilling and performing blasting. The directional drilling technology is adopted for achieving remote breaking of the hard rock mass of the fault footwall floor of the coal face of the mine, the drilling track is manually controlled, the drilling track is purposefully extended along the trend of the hard rock mass of the fault footwall floor, and therefore the breaking effect of the hard rock mass of the fault is maximized; and directional drilling and long-distance blasting crushing work are carried out at the normal stoping position which does not affect the coal face, normal production of the coal face and equipment safety can be guaranteed, long-distance accurate crushing i
