基于含水煤岩声发射特性的矿井底板突水智能监测仪设计

Design of Intelligent Monitor of Water Inrush from Coal Floor Based on Acoustic Emission Characteristic of Moisture Coal-rock

为了提高矿井突水量的预测精度,依据在不同应力速率作用下、不同含水量煤岩破裂时声发射频谱存在差异的特性,介绍了一种基于声发射特性的矿井底板突水智能监测仪,给出了突水危险判断模型,详细介绍了该监测仪的硬件及软件设计,最后对该监测仪进行了实验测试。测试结果表明,该监测仪能为井下突水实时预测提供依据。

In order to improve pridiction accuracy of water irruption quantity of mine, the paper introduced an intelligent monitor of water inrush from coal floor based on acoustic emission characteristic according to spectrums of acoustic emission have difference under diffirent stress speeds and fracture of coal-rock with different water content. It gave judgment model of water inrush hazard, introduced design of hardware and software of the monitor in details, and made experiment test for the monitor. The test result showed that the monitor can provide reference for real-time pridiction of undreground water inrush.
