尽管对钻进设备进行过多次改进,但仍无法解决钻孔垂直度问题。借助钻孔解释物探测量结果,和正确圈出矿体,都必须精确测量出孔斜度。瑞典 Atlas Copco 和 Aga Geotronics公司研制一种有助于测量孔斜的新仪器。该装置位于钻机给进臂上,靠调节指针和仪器管内空气泡的中心度来达到理想倾斜,其误差一般小于0.2%。 Despite many improvements to the drilling equipment, the hole perpendicularity problem still can not be solved. With borehole interpretation of the geophysical survey results, and the correct circle of the ore body, the borehole inclination must be accurately measured. Atlas Copco and Aga Geotronics in Sweden have developed a new instrument to help measure borehole inclination. The device is located on the rig feed arm, by adjusting the center of the pointer and instrument tube air bubbles to achieve the ideal tilt, the error is generally less than 0.2%.
