Abstract: In order to solve the hidden problems of coal mine water hazard detection and governance problems,to solve the conventional drilling construction distance is short, difficult to drill into the detection layer and other issues, based on the coal mine underground screw motor combined with drilling measurement system directional drilling technology, a set of coal mine water hazard exploration and treatment of precision directional drilling construction technology is introduced, by optimizing the borehole design, the trajectory precise control technology, the construction trajectory is precisely controllable for long distance orientation to detect the water hole. The results show that it is possible to save a lot of cost and improve the efficiency of the working face with the risk of water burst, for the detection of rich water, it can be effectively drilled into the design level, to solve the problem of coal mine water detection, coal mine safety production to provide technical support.
