摘　　要：本文针对目前矿井井下煤泥水落后的工艺流程及设备存在的不足,采用矿浆絮凝沉降理论、阶梯溢流、预先处理理论,通过实验室试验和工业性试验,提出从源头解决水仓清挖问题为根本,提前逐级处理325目之上的粗颗粒(不进水仓处理),间接处理了水仓,研究了一套基于无人值守的井下煤泥水清淤系统,重点介绍了核心设备—QCG刮板式清仓机;该系统装备采用“机械化换人、自动化减人”,实现井上地面集控室操作、远成视频监控,井下无人值守,最终实现水仓5年以上(或5~10年)清淤一次;解决了工人的劳动强度问题;提前处理粗颗粒,解决了多级泵的磨损问题;时时清挖(不启用备用水仓),提高了水仓的抗水灾能力,彻底解决了矿井安全隐患。Focusing on the deficiencies in the current technological processes and equipment for handling mine slurry in underground mines,this article proposes a comprehensive solution by utilizing theories of slurry flocculation sedimentation,stepped overflow,and pre-treatment.Through laboratory and industrial experiments,the study emphasizes tackling the problem of sump cleaning from its source by preprocessing coarse particles above 325 mesh(without entering the sump),which indirectly manages the sump.A set of unmanned underground coal slurry desilting system is researched and presented,with a key focus on the core equipment,the QCG scraper-type sump cleaner.This system adopts a strategy of"replacing manpower with mechanization and reducing staffing through automation,"enabling remote operation from a centralized control room on the ground,with video surveillance and no need for personnel in the mine.Ultimately,this system achieves a desilting cycle of over five years(or 5-10 years)for the sump,significantly reducing labor intensity for workers.Preprocessing coarse particles mitigates wear on multi-stage pumps.Regular cleaning(without the need to activate backup sumps)enhances the sump's resistance to water disasters,thoroughly addressing safety hazards in mines.
