我厂测量人员,在鼓足干劲,力争上游,多快好省地建设社会主义总路线和《鞍钢宪法》光辉旗帜的指引下,贯彻执行毛主席的无产阶级革命路线,坚持“独立自主,自力更生”,“走自己工业发展道路”,对井下测量工具和作业方法进行了大量的技术革新,于一九七○年先后试制成功电光锤球、电光横标尺和电光水准标尺,并用于井下测量作业,从而节约了人力,提高了质量和工作效率。在大量的试验工作的基础上,对所积累的第一性资料,做了较为系统的总结分析,研究了采用电光横标尺视差法测距和观测角精度等问题,为我们今后的井下测量创造了一个好的工作条件。几年来,在官帽山硫铁矿区已全面采用上述方法作业,实践证明这些方法是行之有效的,其精度完全能够满足矿山生产的要求。现将三项主要革新工具的构造和制作方法简介如下:
The measurement personnel of our factory, following the principle of building a socialist general line and the glorious banner of the “Anshan Iron and Steel Constitution” with great energy and enthusiasm for the upper reaches, implemented the proletarian revolutionary line of Chairman Mao, insisted on “independent autonomy, self-reliance”, " Taking its own road to industrial development”, a large number of technical innovations were made in the downhole measurement tools and working methods. In 1970, successful electro-optical hammer balls, electro-optic cross scales, and electro-optic leveling scales were trial-produced and used in downhole measurement operations, thereby saving Manpower, improve quality and work efficiency. On the basis of a large amount of experimental work, a more systematic summary analysis of the first-class data accumulated has been conducted. Problems such as the use of electro-optical horizontal-parameter parallax-based distance measurement and observation angle accuracy have been studied and created for our future downhole surveys. A good working condition. Over the past few years, the above methods have been used in the Guanmeishan pyrite area. Practice has proved that these methods are effective and their accuracy can fully meet the requirements of mine production. The structure and production methods of the three major innovation tools are summarized below:
