Improving the efficiency of the maintenance and monitoring system for mine degassing pipelines

Abstract

Degassing pipelines in mine workings frequently change position, causing leaks and joint failures due to geomechanical processes and floor rock heaving, which lead to fatigue and corrosion. This paper reviews maintenance and renovation methods for these pipelines, aiming to develop innovative solutions to enhance operational performance. Research focuses on assessing current maintenance techniques, improving reliability, and implementing new technical solutions under real mine conditions. The proposed technological complex aims to enhance the safety and quality of pipeline maintenance and renovation. Typical production scenarios and monitoring methods for effective control of the technical state of mine degassing systems are considered. Continuous control of degassing wells and pipelines using structural modules of the Automated Mine Degassing Control System (AMDCS) is emphasized. Implementing these modules allows for automatic monitoring of the methane-air mixture and measurement of pressure drops, absolute pressure, temperature, and gas flow volume, thereby providing critical data to operational personnel.
