CAUSES OF DEFORMATION OF TRANSBAIKALIA COAL MINESPIT SIDES

The article deals with mining and geological conditions and problems of development of coal deposits of Transbaikalia, associated with a decrease of the stability and the bearing capacity of the rock in the pit sides, the formation of landslides, highin flows of water into the mine workings. The conditions of formation of coal deposits and Transbaikalia permafrost zone are considered.
Particular attention ispaid to the influenceof cryogenic processesand degradation of permafroston the stabilitysides, slopes and dumps. The permafrost characteristic of maincoal fields: Kharanor, Tataurovsky, Urtuyskiy, Apsatskiy is presented. The history of the formation and transformation of the geological environment of coal deposits of Transbaikalia Neogene-Quaternary period was analyzed.
The featuresof deformation processes in the sides of thecoal minesof Transbaikalia, caused follow inggeological and permafrost-hydrogeological factors are considered. These includephysical and mechanical propertiesof overburden rocksand useful minerals, tectonics and neotectonics, groundwaters, permafrosts, dangerous exogenous processes.
Based on the analysisit was found that thereasons of the active development of the Transbaikalia coal minespit sides deformationis acombination of geological, hydro-geologicaland mine technical factors.
