Summary:

The ¿̐ưNX¿̐ư bore-hole camera was designed and developed by Remington-Rand Corp. and the Army Corps of Engineers for photographing subsurface conditions on the walls of small-diameter borings in rock. The increasing practicality and availability of such equipment for foundation studies and mineral explorations is creating further interest in its use in the study of rocks, some soils, and even in large but otherwise inaccessible openings. Some of the camera's capabilities are presented with techniques of operation and methods of interpretion of geologic features as photographed on either colored or black and white film. Each film frame is a doughnut-shaped picture of a section of the wall of a hole. A graphic method is described for interpreting from a flat photograph the true orientation of the features on the wall of the hole, such as fractures, mineral veins, or geologic contacts and also for determining the true lengths of the lines on the projection. Some examples of interpretative results are also given.
