Method for energizing and retrieving data from deep bore holes uses radio transmission through the wall of the boring column

摘要

A box containing an energy source (3), radio (5) and memory (4) is rotationally attached above ground to the boring column (1). Leads (9) connect to equipment at the lower end as well as (7) to the radio and (11) to the memory unit so that data regarding depth, angle and instructions may be transmitted.
