Abstract

The development of modern physics has promoted the progress of traditional rock physics and mechanics, especially Sheng emission technology based on acoustics. In order to study the acoustic characteristics of rock specimens under compression, the test is carried out with the help of Sheng emission technology, the mechanical characteristic parameters of rock physics and mechanics are measured, and the sound source position and radiation energy parameters of rock fracture are obtained. Combined with the numerical simulation software MATLAB and fractal theory, the energy release mechanism of rock samples is analyzed. The acoustic characteristics of rock samples are remarkable, and the three-dimensional spatial coordinates of rock fracture source can be measured scientifically and accurately, with an accuracy of 99.98%, making it possible to reproduce the three-dimensional fracture source. It is found that the distribution of main fracture sources and high-energy fracture sources can be one-to-one corresponding and consistent with the external fracture failure mode of rock; Through interpolation inversion and energy parameter simulation analysis, slice processing is carried out to obtain the inversion results of energy distribution and test pieces. The process of microcrack propagation and propagation is completely consistent. Based on the analysis of physical mechanics and acoustic characteristics: the numerical simulation analysis of rock specimen failure process can not only reflect the dynamic failure process of rock, but also provide guidance for the prediction and analysis of mine disaster evolution.
