摘要：
In order to ensure safe and efficient coal mining, it is usually necessary to construct a large number of gas drainage holes and water exploring and drainage holes in the coal mine. Directional construction drilling can improve the quality of such drilling construction, measure the main parameters such as drilling inclination angle, azimuth angle and tool orientation angle in real time, draw the drilling trajectory and adjust the drilling attitude according to the needs, realize the efficient utilization of gas drainage, and advance, regional, precise prevention and control of disasters. The measurement while drilling (MWD) system is the necessary support for drilling directional construction, which is applied to various directional drilling rigs in coal mines to measure the drilling trajectory in real time to guide the design and construction of drilling.
