摘要

摘要:本文采用声发射(AE)方法在实验室中对三种不同强度混凝土进行了区分。在全尺寸切削试验台上进行了不同条件下的切削试验，并进行了声发射测量。声发射测量通过震级进行评估。然后，利用移动极大值算法对声发射信号进行处理，并利用处理后的图生成地表等高线图。可以清楚地看到，声发射测量可以根据强度差异来区分被切割的材料，例如高强度混凝土产生的声发射信号强度较高，而低强度混凝土显示的声发射信号强度较低。

Differentiation of artificial rocks in mechanical cutting using acoustics emission (AE) towards selective mining

ABSTRACT In this paper, acoustic emission (AE) method was used to differentiate three concretes having different strengths in laboratory. Cutting tests under different conditions in full-scale cutting testing rig coupled with AE measurements were realised. AE measurements were evaluated by means of magnitude. Afterwards, moving maximum algorithm was utilised to process AE signals, and processed plots were employed to create surface contour plots. It was clearly seen that AE measurements can be used to differentiate materials being cut in terms of strength differences, such that higher strength concrete yielded higher magnitudes of AE signals where lower strength concrete showed lower magnitudes.
