Environmental Monitoring in Polish Coal Mines

Polish coal mines are well equipped with methane monitoring systems,nevertheless the worsening conditions force a continuous impro- vement in the field of environmental monitoring. Application of modern electronic components make it possible to design the new modular telemonitoring system incorporating the best features of the older systems,widely employed in Polish collieries, eliminating their weak points. Several new sensors and portable instru- ments for methane monitoring and early fire detection have been developed and tested in mining conditions.
