摘　　要：针对使用加速度计和磁强计的煤矿近水平钻孔测斜仪,将校准时需要补偿的各种误差独立分解,使用不同数学算法计算高精度的误差补偿系数,形成了一套煤矿近水平钻孔测斜仪校准方法,并用Matlab实现了相应算法,最终有效提高了测斜仪的测量精度。将校准结果与特殊位置法的结果进行比较,说明了该方法的有效性和校准结果的精确性,并对测斜仪产品进行现场试验,给出轨迹测量结果。In view of the inclinometer worked with accelerometers and magnetometers,we analyze the error correction theory to find out all kinds of errors that need to be corrected separately.Different mathematical algorithms are placed to calculate the calibration parameters and a set of calibration method on inclinometer used in coal mine subhorizontal drilling is established correspondingly.The algorithms are implemented and programmed using Matlab as a programming tool to improve the measurement accuracy of the inclinometer.The measuring results on this method and the traditional special position testing method are compared to express the effective and accurate of this method.Field test of the inclinometer have been experimented in the coal mine and the trajectories on the measuring results are showed in the paper.
