LOOSEWALL STABILITY IN UNITED KINGDOM SURFACE COAL MINES

The stability of loosewall slopes in surface coal mines is an important factor in the successful exploitation of surface coal mine reserves. Loosewall instability must be avoided not only to ensure negligible risk to both personnel and excavation plant but also to prevent increased production costs. In 1976 the United Kingdom National Coal Board Opencast Executive initiated a programme of slope stability research projects at the Mining Engineering Department of the University of Nottingham. This paper examines the data collected on loosewall slope failures over the last 10 years. The results of a preliminary programme of back analyses of selected loosewall instabilities using limit equilibrium techniques are discussed.
