ABSTRACT

One of the main problems when carrying out underground mining is to ensure an adequate amount of fresh air in mining excavations. In particular, this applies to longwall workings with powered longwall complexes. These high-performance machine sets enable fast and efficient mining of the rock mass along with the transport of output outside the face zone. The factor affecting their efficiency and effectiveness is adequate ventilation of excavations. The article presents the analysis of ventilation methods of longwall excavations in hard coal mines in Poland and modern systems of registration and monitoring of ventilation parameters in longwall excavations. These solutions require the use of advanced IT and telecommunications solutions. It conforms to the ideas of industry 4.0, which is increasingly used in mining. The practical application of cyber-physical systems can significantly improve the safety and efficiency of mining operations. The example presented in the paper concerns a new longwall excavation, prepared for operation. The use of digital recording and data transmission systems enables the current diagnosis of the methane hazard. The presented concept and research results should improve the efficiency of the entire mining process.
