A discrete two-dimensional Fourier transform and the power Fourier spectrum are used for determination of average strains near cracks in a welded seam of Ni-Cr-Fe alloy. The alignment of Kikuchi images with the help of genetic algorithms and subtraction of white Gaussian noise made it possible to more fully take into account the influence of instrumental factors on the formation of electron backscatter diffraction patterns.

The issues of the impact of harmful emissions from technological processes and productions in a mining and processing plant are considered. Investigations of the sources of the formation of poisonous twisted gases and dust in the atmosphere of the quarry were carried out The quantitative and qualitative composition of dust and gas emissions emitted during blasting operations is considered. The simulation of fugitive emissions of substances into the atmosphere with the definition of the main parameters of emissions during explosions. Based on the analysis of the calculations, it was revealed that the concentration of harmful substances in emissions is many times higher than the MPC, which creates a critical situation in the working areas of the plant. A comparative analysis of the project of limit-permissible emissions into the atmosphere and actual emissions at JSC Lebedinsky GOK was performed.

Existing measures for the suppression of dust and gas emissions during mass explosions at the quarry of a mining and processing plant were investigated. Measures have been developed to reduce dust and gas emissions, taking into account the analysis of existing measures to suppress dust and gas emissions from mass explosions in the open pit of the mining and processing plant of Lebedinsky GOK. The studies of surface active substances on the wettability of dust particles. In order to improve working conditions, it was proposed to reduce dust and gas emissions by suppressing them at the source of education, using the method of wetting and sticking of dust particles. The proposed engineering - technical solution can be used to reduce dust and gas emissions during massive explosions in the quarries of various mining and processing enterprises. The developed method is proposed to be used to ensure environmental safety and improve working conditions in industries with high dustiness by increasing the efficiency of dust collection.
