我队于七九年开始用上海地质仪器厂的JGC-40感光记录测斜仪。截止七九年底，在两个矿区测量了二十八个钻孔（其中小口径钻孔二十一个，大口径钻孔七个），共233个测量点。所测钻孔均为直孔。测得顶角最大倾斜角为45°，测得顶角最小倾角0°10′。测量钻孔的平均孔深为803米，测量最大孔深1201.44米。一、仪器的优点1．重量轻，运输方便。该测斜仪包括所有附件总重65公斤。只需3人一次就可以把仪器运至工作现场。而JXK-2型小口径测斜仪，总重量达580公斤，
My team started in 1979 with the Shanghai Geological Instrument Factory JGC-40 photosensitive inclinometer. Till the end of 1979, 28 boreholes were measured in two mines (of which 21 were small bore holes and 7 were large bore holes) for a total of 233 measuring points. The measured holes are straight holes. The maximum inclination angle of the apex was measured as 45 °, and the minimum apex angle of inclination was measured as 0 ° 10 ’. The average hole depth of the measuring hole is 803 meters and the maximum hole depth is 1201.44 meters. First, the advantages of the instrument Light weight, easy to transport. The inclinometer includes all attachments weighing 65 kg. Only 3 people can once shipped the instrument to the job site. The JXK-2 small diameter inclinometer, the total weight of 580 kg,
