摘要
运用YHQ-X型全方位钻孔测斜仪,确定井下地质前探钻孔的偏斜轨迹,准确控制地质钻孔见煤层、见断层的三维坐标,提高地质资料分析的准确性。同时提出YHQ-X型全方位钻孔测斜仪使用过程中的局限性,并提出改进的方向。
By YHQ-X omnidirectional drilling dipcompass,identifies the skewed trajectory of underground geological advanced exploration drilling,and accurately controls the three-dimensional coordinates of coal seam,fault in geological drilling,improves the accuracy of geological data analysis,meanwhile,puts forward the limitations in the process of using YHQ-X omnidirectional drilling dipcompass and the suggestions for improvement.
