摘要：
矿用水平定向钻机进尺测量和轨迹跟踪的速度和准确性直接关系到开采效率和安全性。综合国内外研究现状，以石壕煤矿井下断层为研究对象，提出采用分段积分测量进尺消除累积误差的孔口钻杆进尺测量方法，并利用模式识别测量固定进尺修正加速度进尺。在此基础上，对孔底随钻姿态参数开展实时测量，获得每个测量点钻孔的方位角、倾角以及深度。室内试验表明：该方法在置信度为95%时，工具角、俯仰角、方位角最大误差分别为±0.6°、±0.8°和±1.1°。现场试验表明：最大测量误差水平方向为0.08 m，垂直方向为0.15 m，末端钻孔俯仰角为0.2°，方位角为0.5°。

Abstract: The speed and accuracy of drilling footage measurement and trajectory tracking of horizontal directional drilling rig have great influence on mining efficiency and safety. Taking the underground faults in Shihao Coal Mine as the research object, the method of measuring the drill rod footage with piecewise integral footage to eliminate accumulated errors was put forward. The acceleration feed method was corrected by measuring fixed feed parameters with pattern recognition. On this basis, real-time measurement of bottom-hole while-drilling attitude parameters was carried out. And the azimuth angle, dip angle and depth of borehole were obtained at each measuring point. Laboratory tests show that the maximum errors of tool angle, pitch angle and azimuth angle are ±0.6°, ±0.8°, ±1.1°, when the confidence of the method is 95%. Field tests show that the maximum measurement error is 0.08 m in horizontal direction, 0.15 m in vertical direction, 0.2° in pitch and 0.5° in azimuth.
