| description | The relevance. Nowadays the special fastening compounds and technologies are widely used to increase the roof and walls rock stability, fill visible open cracks and voids. It can prevent rock or coal collapses and dumps during the repair operations into underground mine workings. The rock chemical fastening technology has been successfully used in Russian and foreign coal mines for over 30 years. The main idea of this technology is bonding unstable massif areas with special compounds. The application area of fastening compounds is very wide. It is well known that the presence of roof and walls rock falls leads to formation of domes, a significant increase in the height of mine workings and to formation of deep coal squeezing in the walls. The presence of domes collapses and deep squeezes are the places of methane accumulations in high workings. It has a current interest in mining when fastening compositions form the new technics for mine workings repair operations. The main aim is rock massif fastening parameters and design solutions development using modern fastening compounds during the repair and recovery of mine workings. Methods: field measurements, statistical processing of results. Results. The paper considers a fastening compounds complex review during the mine workings repair operations. A comprehensive analysis of different fastening compounds in terms of the main bonding component was carried out. It took into account fastening compounds technical characteristics, their application areas and equipment requirements. Eight main groups of compounds were allocated. A technological scheme at workings crossway areas for roof and walls rock fastening using polyurethane compounds injection was proposed. |
