Working environment plays a very important part in human life. In case of underground miner's work the working environment has a lot of hazards caused by geosphere, technosphere as well as atmosphere. Counteraction against atmospheric hazards in underground workings is based mainly on preservation of proper parameters of air composition and physical parameters of the air. Telemetrical systems in Polish mines are subject to intense development from the early 90s of the 20th century. Such systems are intended for automatic measurement of atmospheric air composition as well as its physical parameters. PKiMSA CARBOAUTOMATYKA S.A. from Tychy is one of the companies which had noticed a need to develop multi-directional telemetrical systems. Offer of the CARBOAUTOMATYKA company includes surface telemetrical units, underground units for measurements of chemical parameters as well as physical parameters of the mine atmosphere. Sensing elements operate in the continuous mode while theirs construction enable direct or indirect (after signal's sending to the surface unit) control of external devices, e.g. intended for switching off electric energy in the specified areas of the mine. Measured chemical parameters are concentrations of the following gases: methane, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, nitrogen monoxide and nitrogen dioxide, chlorine, sulphur dioxide, hydrogen cyanide as well as oxygen. Air velocity, absolute pressure, pressure difference, temperature and air humidity are calculated from among physical parameters. Moreover also a rock mass temperature can be measured. This temperature is a basic parameter in heat transfer theories from rock mass to the workings. The mining regulations imposes some measurements of physical and chemical parameters. However fulfilment of regulations requirements gives the necessary minimum safety. More extended safety system is usually used in the mines than it can arise from the regulations and the extension degree depends on evaluation of hazards present. Manual measurements are still inalienable supplementation of the telemetrical measurements. Such manual measurements are carried out in all locations of potential presence of hazard source. Development of the automatic measuring systems and devices intended for individual measurements should be connected with development of measurements interpretation method in order to anticipate beforehand a degree of potential hazard and to plan suitable hazard prevention mechanisms.
