Determination of the reflectivity of minerals for the choice of optimal conditions of photographing at geological photo-documentation of mine workings

Abstract

Improving the quality of geological documentation can be achieved by photographing mine workings and then compiling photographic schemes that are used for primary geological documentation. This method is simple, but is possible when the reflectivity of the minerals composing the deposit is known, which makes it possible to select photographic materials and light filters that give the opportunity to obtain the most contrasting separation of minerals on the photo ....
