探矿深井高程导入方法研究及应用

Study and application of deep well elevation introduction in exploration

对于深井高程导入测量来说,由于受井下环境等多方面的影响,还是制约我们测量人员的一大难题,就拿本公司的探矿井来说,设计深度将近1000m,现已施工至-740m深度已达到900m,并且中间还有几个中段要贯通,时间紧、任务重。为了此井的高程导入测量,我们也是搞了几次了,但是对成果都不是很满意。为了尽快拿出成果,不耽误施工进度,最后反复论证决定用大钢尺量距结合比长台比长的方法来进行,这样的方法以前只是在没有大钢尺的情况下,只用钢丝量距的一种运用,此次他们展开想象把以前用于比长钢丝的方法,运用于现在比长我们所投放的钢尺,这样既可以对测量成果进行比较又可以相互检验。

For deep into the height measurement,influenced by the underground environment and so on,or restrict a big problem that we measure,take mine exploration of the company,the design depth of nearly 1000 m,now construction to-740 m depth has reached 900 m,and there are several middle and communication time,heavy task.In order to measure the height of the well,we have done a few times,but we are not very satisfied with the results.As soon as possible in order to produce results,not to delay the progress of construction,finally decided to use a large amount of repeated demonstration ruler than long distance combined Taiwan than long method,this method was only in the absence of large steel case,using only a wire distance,the imagination of the former than they used to long wire now,with longer than what we put on the ruler,which can carry on the measurement results and comparison of mutual inspection.
