Abstract

The article deals with the issues of labour safety in the mining industry. In order to achieve the goal of the work, the methods of mine atmosphere control have been analysed and improved. Mathematical modelling of the dust meter using nephelometric and turbidimetric methods for measuring concentration and dispersion parameters of dust aerosols has been carried out. The main factors affecting the measurement accuracy, including dust concentration and dispersity, radiation wavelength and geometrical parameters of the optical system, are investigated. It is revealed that the turbidimetric method is more sensitive in measuring low dust concentrations, and the nephelometric method is more effective in determining high concentrations.
