Assessment of Corrosion Phenomena of Hydromechanical Fittings and Elements of Excavation Support Under the Conditions of Active Mine Exploitation

Ciosmak Małgorzata, Parzniewski Tomasz

Journal of Ecological Engineering

2023

Vol. 24, nr 5

337--345

The paper presents the results of observations and research conducted in the Lublin Coal Basin (LCB), particularly during active coal mining. The mining technology is characterized by the extraction of usable minerals using underground methods. The safety of the mining operation, both for the people working there and the efficiency of the machinery, requires the use of excavation protection, as well as dewatering of geological layers lying above the zone of the mining operation. The quality of water and air as well as the materials used in the mine create the conditions conducive to corrosion. The duration of contact with the conditions conducive to corrosion and erosion is also important. While working under load, elements of the excavation lining and hydromechanical fittings are exposed to the formation of material defects, which can lead to the occurrence of emergency situations or even their destruction. The authors identify the phenomena conducive to corrosion and indicate the need for their further investigation.
