The laws determining formation of the stress-strain state of the rock mass round development workings of coal mines and potassium pits, having low-power weak intermediate layers in their floor and roof have been found out. A technique of predicting a stability loss of floor rocks and methods of estimation of their expected displacements in development workings retained for their repeated use, regional and local means of protection of development working, means of mechanization of unloading slots have been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
