華东煤田地質勘探局一二二隊在1955年11月份領到國産仿苏联造包良可夫式鑽孔测斜仪一架,經初步試用,效果良好。首先由于该仪器装有罗盤和顶角刻度盤,所以当测斜仪在孔内工作完畢,提出孔口后,鑽孔的顶角和方位角就可以直接讀出,不必另行計算。同时南于操作簡便,从而節省测斜时間,增加純鑽進时間,一二二隊是用鑽具把测斜仪送到孔内進行测斜的,300公尺深的鑽孔测斜一次,包括上下鑽具只用一小时(編者註:如能用專用的鋼絲繩升降测斜
Huadong Coal Geological Exploration Bureau 122 team in November 1955 received a copy of the Soviet-made domestic production of Liangkov-style borehole inclinometer, after a preliminary trial, the effect is good. First of all, because the instrument is equipped with a compass and apex dial, so when the inclinometer in the hole work is completed, put the orifice, the drilling angle and azimuth can be read directly, without having to be calculated separately. At the same time, the South is easy to operate, saving the time of test-tilt and increasing the time of pure drilling. The 112 team used the tool to send the inclinometer to the hole for inclinometer drilling and drilling at a depth of 300 meters Once, including the upper and lower drilling tools only one hour (Editor’s Note: If you can use special wire rope lift tilt
