我矿的激光指向仪是在学习兄弟矿山经验的基础上,自己重新设计、加工制成的,共五台,1977年投产使用。我矿的竖井为方井,净断面5.2×2.6米,井深432米。当井筒掘至60米深时,就可安置激光指向仪(井的四角各安置一台)。掘井210多米后,激光管一次都未更换过,证明使用情况良好。激光投向误差可控制在2厘米以内,比垂线指向稳定,符合矿山测量规程要求。(一)结构该指向仪由激光电源、激光器、带调平螺丝的旋转轴和望远镜等四部
My mine’s laser pointing device is based on the experience of brothers mine, re-designed, processed, a total of five units, put into operation in 1977. Mine shaft for the square mine, the net section 5.2 × 2.6 meters, 432 meters deep. When the wellbore is dug to a depth of 60 meters, the laser pointer can be placed (one at each of the four corners of the well). After drilling more than 210 meters, the laser tube has not been replaced once, proving good use. Laser error can be controlled within 2 cm, more stable than the vertical line, in line with the requirements of mine measurement procedures.
