测量磁性矿区勘探钻孔的顶角和方位,除少数单位使用电测仪或陀螺仪外,多数使用定盘仪或两用测斜仪.后两种测斜仪在结构上都存在一些缺点,加之钻孔施工时往往出现一些复杂情况,影响测斜结果的可靠性.野外勘探队常由于仪器不足,配件缺,检修质量差等原因,给测斜工作带来很多困难,以致满足不了施工的要求.毛主席关于学习理论,反修防修,评论《水浒》等重要指示大大激发了我队广大工人、干部和技术人员的干劲,在学习黑龙江地质二队显影测斜经验的基础上,对这种方 Measurement of the magnetic mining area drilling angle and azimuth, with the exception of a few units using electrical measuring instrument or gyroscope, most of the use of fixer or dual inclinometer.The latter two inclinometers have some shortcomings in the structure, In addition, some complex situations often occur during borehole construction, which affects the reliability of the results of the incline test.The field exploration teams often cause many difficulties in inclinometer work due to lack of equipment, lack of spare parts and overhauling of quality, which can not meet the needs of construction Requirements, Chairman Mao’s important instructions on learning theory, anti-revisionism and anti-revisionism, and comment on “Water Margin” have greatly inspired the motivation of the vast majority of workers, cadres and technicians in our team. On the basis of studying the development experience of the second team of Heilongjiang Geological Team This side
