Abstract: In view of the characteristics of the existing display instrument mounting in drilling rig which is dispersed, rare kinds and should not be stored, parameters measurement system of tunnel drilling can complete the coal mine drilling better. The characteristics of parameters measurement system are introduced in this paper, and the industrial test of Qi'nan Coal Mine in Huaibei Mining Industry Group is taken as an example, the application of the drilling instrument and track meter of the system is expounded. Application results are shown that the system can alarm in real time when borehole is abnormal and determine whether the accident belongs to the burying drill through the drilling parameters of the instrument software,and hole accident can be prevented; borehole deviation based on the trajectory of two-dimensional or three-dimensional figure can be known, and the late drilling construction can be guided by the combination of both, and the effect of coal seam gas drainage can be improved.
