Digital survey in studying open pit wall deformations

Abstract

The article highlights the topical problem of increasing efficiency of survey during monitoring of rock and earth surface displacement when studying various kinds of deformations caused by mining. To settle the problem, new methods based on use of new devices, programmes and technologies are applied along with traditional ones. The object of the study is an open-pit slide. As it is dangerous to stay on, remote monitoring methods become the most efficient ones, digital photogrammetric survey being one of them. Digital survey methods are being improved along with development of more sophisticated devices and software. The article deals with the method of open-pit slide monitoring involving digital ground survey with the Canon EOS1200D camera. Camera station reference was performed on the basis of GPS data and marker reference – by intersections.
