Abstract:

Purpose. Development of methods for determining the required volume of air for airing workings by the factor of exhaust gases from internal combustion engines (ICE).

Methodology. To determine the actual value of the cleaning efficiency (neutralization) of exhaust gases from automotive diesel emissions from engines which meet the environmental standard Tier III, field measurements on the magnitude of the carbon monoxide concentration (CO) and nitrogen oxides (calculated as NO2) after the catalytic converter were processed; they were conducted in the conditions of the “United Kirov mine” and the Maleevsky, Tishinsky and Dolinny mines of “Kazzinc” LLC (RF).

Findings. The calculation of specific air consumption according to the method developed by the authors has demonstrated that its maximum value for the Tier III environmental standard is achieved when diluting emissions of nitrogen oxides and is equal to 2.86 m3/min. per hp.

Originality. During the study in the field of exhaust efficiency of gas purification after the neutralizer, the gas-cleaning coefficient was derived and applied in the method for calculating the amount of air. Studies performed in the area of calculating the specific air flow rate by the exhaust dilution factor have shown the possibility of significantly reducing the amount of air supplied to the atmosphere of the mine to dilute harmful impurities to standard values.

Practical value. The calculation of the amount of air according to modern standards of diesel equipment will allow reducing the cost of ventilation of mine workings. This will increase the service life of equipment involved in the ventilation of mine workings, and significantly reduce the capital costs of mining enterprises, which will lead to positive economic effect.
