【摘要】：搭建了礦井突水相似模擬實(shí)驗(yàn)系統(tǒng),研究了礦井突水演化過(guò)程中電磁輻射、聲發(fā)射和表面電位信號(hào)變化特征。研究結(jié)果表明,礦井突水過(guò)程中巖層電磁輻射、聲發(fā)射和表面電位信號(hào)基本呈現(xiàn)初期平穩(wěn)、中期波動(dòng)較大、后期快速減小的變化趨勢(shì);3種信號(hào)均與底板巖層的破裂成正相關(guān)關(guān)系,可反映礦井突水過(guò)程煤巖內(nèi)部破裂情況;3種信號(hào)的快速增大可作為巖層發(fā)生破裂的前兆,而電磁輻射信號(hào)增大后突然減小可作為突水即將發(fā)生的征兆。
[Abstract]:The similar simulation experiment system of mine water inrush is built, and the characteristics of electromagnetic radiation, acoustic emission and surface potential signal in the process of mine water inrush evolution are studied. The results show that the electromagnetic radiation, acoustic emission and surface potential signals in the process of mine water inrush are basically stable in the initial stage, fluctuate greatly in the middle period, and decrease rapidly in the later stage. All of the three signals are positively correlated with the fracture of floor rock, which can reflect the internal fracture of coal and rock during the process of water inrush in mine. The rapid increase of three kinds of signals can be regarded as the precursor of rock burst, while the sudden decrease of electromagnetic radiation signal can be regarded as a sign of the imminent occurrence of water inrush after the increase of electromagnetic radiation signal.
