Mechanization of selective excavation of oil shales

Abstract

The existing technology of oil shale extraction provides for simultaneous extraction of the entire industrial oil shale stack. This provides the fastest and least labor-intensive destruction of oil shale and allows for mechanized loading in chambers - longwall faces in the case of bulk excavation. However, this method leads to mixing of oil shale and rock, and manual sampling in longwall faces is very labor-intensive and unpromising in terms of increasing labor productivity ...
