Key technology status and prospect of intelligent rapid excavation in roadway of coal mine

  • 摘要: 巷道智能快掘技术是智慧矿山建设的关键保障之一,是解决采掘接替失衡问题的主要方法。随着掘进设备的发展,我国智能快掘装备经历了由综掘机到掘进机+锚杆钻车再到掘锚一体机,掘-支-运实现了平行作业。针对智能快掘保障技术不足的问题,总结提出了超前钻探、多套钻机协同顺序作业、精准高效智能导向、截割机构实时位置虚拟在线、成套装备的智能连锁控制、故障自诊断及在线监测6个智能快掘保障技术,同时基于设备优化,提出了截割机构进给速度与截割速度的匹配、锚杆钻机优化布置、运输系统各设备之间合理衔接及智能化快掘成套装备除尘系统4个配套设计。智能快掘系统相较于传统掘进系统,掘进效率更高、投入人员更少、安全程度更大。而后总结了现阶段智能快掘技术的不足及发展趋势,以及智能快掘煤矿掘进发展的必然趋势,具有广阔的市场前景。

     

    Abstract: Roadway intelligent rapid excavation technology is one of the key guarantees of smart mine construction, and is the main method to solve the problem of mining and extraction succession imbalance.With the modernization of excavation equipment, China's intelligent rapid excavation equipment has experienced a change from comprehensive rapid excavation machine+anchor drill truck to integrated excavation and anchor machine.Parallel operation of excavation-supporting-transportation is realized.Based on the lack of intelligent rapid excavation security technology, six intelligent rapid excavation guarantee technologies are summarized: advanced drilling, coordinated sequential operation of multiple sets of drilling rigs, precise and efficient intelligent guidance, virtual online position of cutting mechanism in real time, intelligent chain control of complete sets of equipment, fault self-diagnosis and online monitoring.At the same time, based on equipment optimization, four supporting designs are proposed: matching the feed speed of cutting mechanism with cutting speed, optimizing the arrangement of anchor drilling rig, reasonable connection between various equipment of transportation system and intelligent rapid excavation equipment dust removal system.The intelligent rapid excavation system has higher efficiency, fewer personnel and greater safety than traditional excavation systems.Summarizing the shortcomings and development trend of intelligent rapid excavation technology at the current stage, the author has concluded that intelligent rapid excavation is an inevitable trend in the development of coal mine excavation.
