摘要
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 roadway structure stress, this paper makes a detailed analysis of the computer hardware system and software system of online monitoring system, and introduces the main function of the on -line monitoring system working principle and monitoring system software. The computer monitoring system is used for real - time monitoring of bolt and anchor axial force, the moni- toring results show that the rock burst greatly affect the stress of bolts and cables, when the rock bursts, it will lead to a sudden increas- ing or sudden unloading in the axial force of bolt, if the impact repeats, it will cause cable fatigue breaking. According to the anchor and anchor monitoring results, corresponding measures can be taken to prevent the failure of roadway.
