COAL DEACTIVATION UNIT

The coal deactivation unit (UDU) is designed to work with equipment that supplies water aerosols to the mined-out areas of operating production faces (longwalls) with the purpose of preventing endogenous fires.

COAL HARDNESS ANALYZER

The coal hardness analyzer (POK-1) is designed to determine coal hardness during outburst prediction of coal seam zones that are opened by crosscuts and drifts.

CORE SAMPLER

The core sampler is designed for coal core sampling during drilling of the holes crossing the zones of coal seams to be uncovered in order to determine hardness coefficient on M. M. Protodyakonov’s scale when performing outburst prediction before uncovering coal seams.

MINE AIR TEMPERATURE INDICATOR

The mine air temperature indicator ITRV-1 is designed to monitor the development of coal spontaneous combustion in the mined-out space of existing and abandoned mine sections, in domes and above mining excavation roof support, in pillars and concentrated accumulations of shattered coal based on the temperature dynamics.

STRENGTH MEASURING TOOL

The strength measuring tool (P-1) is an express method to determine coal strength parameters in the face.
