As coal mines deepen, the likelihood of sudden emissions increases. At present, seismic acoustic stations (SAS) have been created at all deep coal mines in Donbass, the operators of which listen to the sounds coming from the geophones in order to identify the precursors of the emission - seismic impulses.

The literature does not reflect the working conditions of CAS operators, whose work has a number of physiological and hygienic features that distinguish it from other professions. ,

The working conditions of the SAS operators at 4 mines with flat and inclined bedding of coal seams have been studied and measures have been developed to improve them. The studies were carried out in warm, transitional and cold periods of the year.

Based on the studies carried out in accordance with the methodological recommendations [1], the work of the SAS operators, according to the largest quantitative criterion, was characterized as very intense. Measures have been developed to improve working conditions for CAS operators. The main ones include: unloading the auditory analyzer by reducing the listening paths to 2, distributing the load between the auditory and visual analyzers due to a device that works like a color music, rationalizing the workplace and work and rest modes, increasing the motor activity of operators.

Experimental implementation of these recommendations on one CAS has shown their high efficiency.
