Abstract: The possibility of filling empty underground spaces, which exist owing to extracting mineral raw materials, with light ash and cement light ash mixes have been studied for the purpose to reduce the impact of deep mining on the surface. The method of physical modelling was used to study the behaviour of light ash mixes deposited in extracted mine spaces. The models were constructed for two different geometries of underground extracted mine spaces - into cavities of the type of large slits created in the course of mining in steeply lode deposits without subsequently filling the empty space and in vertical shafts of rectangular or circular crosssection with horizontal side headings which have partly caved in due to mine shocks or other seismic events. |
