Experimental Study on Acoustic Time Series Characteristic of Rock Damage

Yue Li, Honglan Shan, Shuai Huang

Abstract

Due to the special geology conditions of metallic mines, an experiment of acoustic emission was carried on the rock to determine the acoustic time series characteristic in metallic rock damage. The critical acoustic emission parameters of rock damage were analyzed and the breakage principle and characteristic of the acoustic emission signals were studied. Comparison tests were individually carried out on homogeneous specimens with cracks. Because of the crack, the regularity of acoustic emission signal of specimen was generalized. The contact surface by reduced rigidity simulated the inner impair of rock and the breakage of rock was studied by different simulated condition. The new method was proposed to study the acoustic emission regulation of impaired rock.
