辽宁某金矿竖井由于岩石不好,受地压影响,发生了变形,大罐运行受阻。为掌握井筒变形的情况,必须对其进行变形检查测量。以往的办法是:先在井筒内放置钢线,再挂上钢尺,然后检测人员乘坐特制的小型罐笼,以钢线、钢尺为准,对竖井进行检查测量。这种方法费用大(小罐笼需上千元),而且无安全设施。另外,在测量细部时一旦碰到钢线,很长时间稳定不下来,这样占用井筒的时间长,影响生产。为克服上述问题,我们采用了激光代替钢线的办法,免去做小罐笼的费用,其效果也很好。方法是:利用激光指向仪作激光源。按激光指向仪的外形尺寸做一金属架,架上设置三个顶丝。金属架的作用是将激光指向仪固定在井框上;顶丝是为了调
A gold mine shaft in Liaoning due to rock is not good, affected by the pressure, the deformation occurred, blocked the operation of large pots. In order to grasp the wellbore deformation situation, it must be deformed to check the measurement. The previous approach is: first place the steel wire in the wellbore, and then hang the steel ruler, and then inspectors take a special small tank, with steel wire, steel ruler shall prevail, the shaft for inspection measurements. This method costs (small cage need a thousand dollars), but no safety facilities. In addition, in the measurement of detail once hit the steel line, a long time does not stabilize, so take up the wellbore for a long time, affecting production. To overcome the above problems, we use a laser instead of steel wire, eliminating the cost of doing small cage, the effect is also very good. Method is: the use of laser pointing instrument for the laser source. According to the shape of the laser pointer to make a metal frame, the frame set three top silk. Metal frame is the role of the laser pointing device fixed in the well frame; top wire is to tune
