Application of Directional Drilling Technology in F_d13 Fault Detection

According to 3D seismic data that F_d13 fault, which affects the roadway layout of 22110 working face transportation roadway, is in 22110 working face of a coal mine, in order to solve the problem of arranging 22110 working face caused by the fault, taking the reasonable division of 22110 working face, the use of underground MWD directional drilling technology, according to the analysis of two main holes and five branch holes and drilling data, we effectively detect the fault location, fault displacement and direction of F_d13 fault in coal mine, which provides the basis for the reasonable arrangement of cutting hole in coal mine 22110 working face.
