Fire prevention

The GCA Mining nitrogen refrigerating unit is designed to be used in underground workings of coal mines, in workings of ‘a’, ‘b’ or ‘c’ level of methane explosion hazard and in workings of "A" or "B" class of coal dust explosion hazard

The container nitrogen generator type PSA is designed for continuous generation of nitrogen of purity min. 97%, with flow rate 700Nm3/h and pressure 6-8 bars from atmospheric air.

The modular mixer type MP is designed for preparation of aqueous mixture of A and B components of foamed mining inhibitor SIG-1.

The main task of SIG-1 is the reduction of coal self-heating tendency by the deactivation of its surface, and thereby the extension of fire incubation period.

We have great experience in construction, modernisation, reconstruction and maintenance of air conditioning systems in coal mines in Poland and the Czech Republic
