冲击矿压是矿山开采中发生的煤(岩)动力现象之一,这种动力灾害通常是在煤(岩)力学系统达到强度极限时,聚积在煤(岩)体中的弹性能量以突然、急剧、猛烈的形式释放,在井巷发生爆炸性事故,造成煤(岩)体振动和破坏,动力将煤(岩)抛向井巷,同时发生强烈声响,造成支架与设备、井巷的破坏以及人员的伤亡等。矿井冲压事故危害性极大,严重影响矿山的安全生产。因此,人们一直在探索其规律并寻求有效的预测方法。自从Obert 和Duvall 发现岩石具有声发射现象以来,岩体声发射技术在矿山得到了广泛的应用。用仪器检测、分析声发射信号和利用声发射信号推断声发射源的技术称为声发射技术。声发射技术是根据结构内部发出的应力波来判断内部损伤程度的一种新型动态无损检测方法。它可以在构件或材料的内部结构、缺陷或潜在缺陷处于运动变化的过程中进行动态检测、监测和评价构件的结构完整性。本设计是利用虚拟软件LabVIEW对冲压矿井的地音信号进行模拟和预测,用小波变换对含噪声的地音信号进行去噪处理。对去除噪声的地音信号进行分析处理。

Abstract:
Rock burst is one of dynamic phenomena in mining, this dynamic disaster generally happens when mechanical system of coal (rock) reaches ultimate strength and the flexible energy accumulated in coal (rock) release suddenly, sharp, fiercely, it can cause explosive accidents in mine, and vibrate and destroy the coal(rock), the dynamic power throws coal(rock) to the mine, and strong sound happens simultaneously, stent and equipments and mine may be destroyed and The casualties will be occurred, etc. Rock burst accident is great harmful and serious to mine’s safety production. So, people have been exploring the rules of rock burst and seek an effective way to predict it. Rock mass acoustic emission technology has been widely used when Obert and Duvall discovered that rock has the ability of acoustic emission. Detection of using instruments, Signal Analysis of acoustic emission and to deduce the destination of acoustic emission, these called acoustic emission technology, Wh
