To address the challenges of significant pressure loss,poor liquid supply stability,and low intelligent control level faced by traditional liquid supply technologies for fully mechanized top coal caving(FMTC)working faces with the increasing advance length of coal mining faces,and to meet the requirements of efficient and safe mining,this study takes the 221304 intelligent FMTC working face with an annual output of 10 million tons in Xiaojiawa Coal Mine as the research object,conducting research on 4500 m ultra-long-distance liquid supply technology.By analyzing the characteristics of pipeline pressure loss,the optimal scheme of a single-supply and single-return liquid supply pipeline with Φ133 mm×12 mm is determined.Combined with vibration suppression,stress monitoring and other technologies,pressure loss is reduced and pipeline stability is improved.Through integrating intelligent sensing,remote collaboration and other technologies,a"cloud-edge-terminal"three-level intelligent control architecture is constructed,and adaptive fuzzy PID and other algorithms are adopted to achieve precise system regulation.Field application results show that this technology reduces pipeline pressure loss by 18.7%,decreases the monthly average failure rate by 42.2%,and improves maintenance efficiency by 45.9%,ensuring the working face's annual production capacity of 10 million tons.This technical system enhances the reliability and intelligence level of the ultra-long-distance liquid supply system,provides a mature paradigm for deep and complex coal seam mining,and has significant promotion value for promoting the intelligent and green transformation of the coal industry.
