Abstract

Purpose. Assessment of technologies and technical means for the using of the phenomenon of an aqueous solution of the natural bischofite in the field of ecology and the mining industry, taking into account the use of solution of the natural bischofite during blasting operations, to prevent of the freezing of rock mass in wagons and ice on highways in quarries, to combat the release of dust during transportation of rock mass by railway transport, during mass explosions in quarries, on quarries highways and at tailings storage facilities. Research methods. During the studying, systematization, and generalization of technologies and technical means of using solution of the natural bischofite, was used the analysis of research and publications, the results of industrial and experimental research at landfills, using standard and new methods with the participation of authors and leading specialists in this field were used. Scientific novelty. The main scientific, practical and social results of the evaluation of technologies and technical means for the using of the phenomenon of aqueous solution of natural bischofite in the field of ecology and mining industry are presented. Practical significance. The technology to prevent winter slippage on quarry roads using solution of the natural bischofite has been developed and implemented. Recommendations are given for combating the release of dust during the transportation of rock mass by rail, during the mass explosions in quarries, on quarry highways, and at tailings storage facilities of GZK, using solution of the natural bischofite and bituminous emulsion, which allow to effectively fix dusty surfaces from dust blowing. Results. When using solution of the natural bischofite instead of water during blasting operations in quarries, the natural bischofite costs are reduced by 1.4-1.5 times and emissions of harmful gases during blasting are reduced by 20-30%. In underground mining operations, when water is replaced with solution of the natural bischofite for moistening natural bischofite granules, the release of gases during a mass explosion in the mine is reduced by 1.3-1.4 times. To prevent the freezing of the rock mass to the inner surface of the open wagons during transportation in the frost, preventive treatment of the inner surface of solution of the natural bischofite railway wagons is carried out. In order to prevent ice on highways in quarries, they are pre-treated with solution of the natural bischofite
