Abstract.

Specificity of operation of the up-to-date tachometric device impellers made of different materials and applied in the world mining practices is analyzed in the article. It is noted that mechanical durability of the impeller is a basic indication of their effective operation at different speed of the air flow with maintained accuracy of measurements and maximally possible values. A method is proposed for calculating tensions which cause bending moments in the impeller due to the speed pressure of the air flowing onto the impeller. This method makes possible to choose optimal material for the impeller making with taking into account all measurable factors which can impact the impeller quality. The article also presents basic principles of the method for measuring sections of the mine tunnels of arbitrary shape. The findings can be used for improving the existing model APR-2 and for designing a pre-production model of a device for controlling air consumption and tunnel depression.
