  • 摘要
    为了缓解采掘失衡、效率低、用人多、装备老旧化、施工工序多,以达到采掘有序接替、装备智能化、掘进快速化,实现矿井安全高效有序生产,针对掘进工作面过断层时存在安全隐患大、煤质差和粉尘浓度大等问题,提出了智能化掘进系统过断层工艺,得到:(1)掘锚机→锚杆转载机组→带式转载机→带式输送机成套掘进装备,实现掘锚一体、锚运破一体掘进工序,提高支护效率、降低人工支护强度、减少支护产生的粉尘及设备移动频率。(2)智能化集控操作系统由工作面集控中心、区队集控中心和调度集控中心构成,均可对掘锚机、锚杆转载机组、带式输送机、局部通风机、除尘箱及配电硐室、照明、通信、摄像头和排水设施等设备进行远程控制。集控中心主要由5G技术、传感器和摄像头对设备进行远程控制,实现自动割煤、行走、喷雾除尘等动作,达到“无人则安”境界。(3)通过FLAC3D数值模拟软件对成套智能化掘进系统快速过断层处支护设计参数进行模拟分析,采用“圆钢锚杆+钢筋网+锚索+W钢带”联合支护的方式后围岩控制效果良好。
  • Abstract

    In order to alleviate mining imbalance, low efficiency, employing more than, old equipment, the construction process, to achieve the orderly mining succeed, intelligent equipment, excavating the rapidness, realize the mine safety and efficient and orderly production, in view of the tunneling faces crossing fault unsafe problems such as big, coal quality is poor and dust concentration, intelligent driving system was put forward through fault process, get: ① A complete set of tunneling equipment, including anchoring machine, bolt reloading unit, belt reloading machine and belt conveyor, can realize the tunneling process of integrating digging and anchoring and transporting and breaking, improve the support efficiency, reduce the strength of artificial support, reduce the dust generated by support and the frequency of equipment movement. ② The intelligent centralized control operating system is composed of the face centralized control center, the district team centralized control center and the dispatch centralized control center, which can be used for remote control of the digging anchor machine, the bolt transfer unit, the belt conveyor, the local ventilator, the dust removal box and the distribution chamber, lighting, communication, cameras and drainage facilities. The centralized control center is mainly controlled remotely by 5G technology, sensors and cameras to realize automatic coal cutting, walking, spray dust removal and other actions, so as to achieve the state of “no one is safe”. ③ FLAC3D numerical simulation software is used to simulate and analyze the support design parameters at the rapid fault crossing of a complete set of intelligent driving system. The combined support method of "round steel bolt + steel mesh + anchor cable +W steel belt" has a good control effect on surrounding rock, which has certain reference significance for the rapid fault crossing under similar geological conditions.
