Abstract：Aiming at the hidden risLs of coal mine water hazard detection and governance difficulties, to solve the problems of short construction distance, drilling difficulty into the detection layer and other issues in conventional drilling, a set of coal mine water hazard exploration and treatment of precise directional drilling construction technology is introduced based on the combination of coal mine underground screw motor and drilling measurement system directional drilling technology, which realizes the construction trajectory precisely controllable for long distance orientation to detect the water hole through borehole design optimization and trajectory precise control technology. The results show that it is possible to save a lot of cost and improve the efficiency for the worLing face with water burst risL; as for the detection of rich water, it can be effectively drilled into the design level, to solve the problem of coal mine water detection, and provide technical support coal mine safety production.
