METHOD OF DETERMINING INTENSITY OF DUST CONCENTRATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01N5/00 

FIELD: mining.

SUBSTANCE: invention relates to mining, in particular to safety and health regulations during development of minerals, and can be used to determine intensity of dust concentration. Method of determining intensity of dust concentration involves determination of dust content, dispersed dust composition, moisture content, temperature, air flow speed. Herewith the level of dust content and the dispersed dust composition are determined using the optical method of small scattering angles considering the ambient air moisture content and the air flow speed with evaluation of dust propagation along the length of the mine working. For the method implementation proposed is a sensor for controlling the intensity of dust concentration including a power supply unit, an information processing and transmitting unit, a line for transmitting data to a display, which additionally comprises a module of optical radiation and optical radiation receivers located at different angles to the radiation source and transmitting information to a dispersed dust composition measurement module, an air flow rate measurement module, a moisture content measurement module, a temperature measurement module, an air pressure measurement module, all transmitting information to the information processing and transmitting unit, where all signals are logically linked to signals obtained from the dispersed dust composition measurement module, performed are calculation of dust dispersion and evaluation of intensity of dust concentration.

EFFECT: technical result is higher accuracy of monitoring the state of the atmosphere dust-explosion proofness due to the use of the optical method of small scattering angles for determination of dust dispersion and increasing the number of parameters characterizing the state of the atmosphere.
