[0002] In the coal mine underground drilling operation, accurate opening positioning is very important for gas drainage drilling, water detection and drainage drilling and other constructions. The traditional opening positioning method mainly relies on the geological compass to measure the azimuth and inclination of the opening. However, due to the complex construction environment in the coal mine, especially the magnetic field interference of the drilling rig and the coal wall metal support, the measurement accuracy of the geological compass is seriously affected, and it is difficult to meet the needs of high-precision drilling. In addition, the MK series drilling rig and other non-directional drilling rigs cannot perform post-trajectory correction, so that small deviations in opening parameters may cause the drilling construction trajectory to deviate greatly from the design requirements, affecting the construction quality and safety.

[0003] In recent years, the development of high-precision gyroscope measurement technology has gradually popularized the application of opening positioning instrument in drilling construction. Such equipment has the advantages of automatic north-seeking and real-time tracking measurement, greatly improving the accuracy of drilling opening positioning. However, the existing opening positioning instrument cannot be stably and safely fixed on the drilling rig during use, and the measurement personnel often need to hold or temporarily place the instrument for measurement, making it difficult to achieve continuous measurement and parameter tracking. In addition, if there is still deviation after adjusting the posture of the drilling rig, the measurement personnel need to adjust repeatedly, resulting in a decrease in measurement efficiency and failing to fully utilize the advantages of the opening positioning instrument. Therefore, there is an urgent need for a fixing device that can stably fix the opening positioning instrument and ensure that its orientation is consistent with the direction of the drilling rod, in order to improve the measurement accuracy and operation efficiency of drilling construction.
