Design and application practice of remote centralized liquid supply system for comprehensive mining faces
Remote centralized liquid supply is an important development direction for intelligent liquid supply technology in coal mining faces,which has great significance for improving the underground working environment,reducing safety hazards,and protecting occupational health.Taking the remote liquid supply system of the 31117 comprehensive mining face of Jinjie Coal Mine of Shendong Coal Group as the research object,the composition of the remote liquid supply system,pressure loss calculation,and analysis of the liquid supply effect are elaborated in detail.The practice has shown that centralized liquid supply systems can meet the high-pressure liquid demand of 5500m ultra remote working faces.
