Development of formulations and the mechanism of activation of mixtures for underground mining with use of mill tailings

The basic solution, allowing to provide safety and sufficiently high efficiency of underground mining of fields in becoming complicated mining-and-geological and mining conditions, use at production of ores of filling method. From all systems of development existing today fi lling method, the greatest effi ciency reach when using hardening concrete mixes. Results of laboratory researches on development of compoundings and the mechanism of activation of hardening concrete mixes are given in article for underground mining of minerals with use of mill tailings. The conducted researches allowed to reveal regularities of increase of reactionary properties of fi lling method with the chosen activator.
