SAK——地音监测系统是评价冲击地压危险程度的实时连续监测系统,此系统在 PRS——4计算机的控制下,可以对矿区井下发生的地音信号进行实时记录和数据分析、处理。它以自动输出信息和报告的形式向矿调度和领导提供评价冲击地压危险程发的依据。一、地音监测的原理在矿山井下内应力异常区岩体和煤层中形成裂隙,在裂隙的扩展和岩体、煤层中发生碎裂的过程中,都会出现其它类型的矿压显现,随之也就产生了地音。在岩体和煤层破坏的过程中,蓄积在岩体内的一部分弹性能量转换成声波能。根据断裂密度,断裂的方位,应力区和裂隙形成
SAK-Tone Monitoring System is a real-time continuous monitoring system for evaluating the risk of rock burst. Under the control of PRS-4 computer, this system can record and analyze the geoacoustic signals in the mine area in real time. It provides the basis for the dispatching and leadership of mines to assess the risk of rockburst in the form of automatic output of information and reports. First, the principle of geo-sounding In the mine underground stress anomaly area of rock and coal seam in the formation of cracks in the expansion of rock and rock, coal seam occurred in the process of fragmentation, there will be other types of rock pressure show, followed by Also produced a local tone. During the destruction of rock mass and coal seam, a part of the elastic energy accumulated in the rock mass is converted into acoustic energy. According to the fracture density, fracture orientation, stress zone and fracture formation
