为了评价巷道支护结构的受力情况,详细分析计算机在线监测系统的硬件系统和软件系统,并介绍了在线监测系统工作原理和监测系统软件的主要功能,采用计算机在线监测系统对锚杆和锚索轴力进行了实时监测,监测结果表明:“煤炮”冲击严重影响锚杆和锚索的受力情况,当“煤炮”冲击时,会导致锚杆轴力突然增加或突然卸载,多次冲击时,还会造成锚索的疲劳破断。根据锚索和锚杆监测结果,可以采取相应措施,防止巷道发生失稳破坏。
In order to evaluate the force of roadway supporting structure, the hardware system and software system of online monitoring system are analyzed in detail. The working principle of online monitoring system and the main functions of monitoring system software are introduced. By using computer on-line monitoring system, Cable axial force was monitored in real time. The monitoring results showed that the impact of “coal cannon” seriously affected the stress of the anchor rod and the anchor cable. When the impact of “coal gun” impacted, the axial force of the anchor rod would suddenly increase or Suddenly unloaded, repeated impact, but also cause the cable breakage fatigue. According to the results of cable and bolt monitoring, measures can be taken to prevent the instability of the roadway.
