比较法丈量钢丝长度测量井深

Comparison measurement wire rope length measurement depth

本文开创了丈量钢丝的新方法,利用已知深度的矿井或可用测距仪,直接测量出矿井的深度,进行钢丝比长,求得待测矿井的深度,从而将地面已知点高程传递到井下未知点上,完成竖直矿井的高程传递工作。

DD wire created a new method known depth of the mine or can be directly measured range finder depth of the mine shaft,steel than the long,and get measured the depth of the mine,which will be known at the ground elevation transmission Underground unknown to the point of complete vertical elevation transfer of the mine.
