“…Accordingly, the AE signal processing methods can be classified into three categories: (i) signal processing, (ii) feature extraction, and (iii) pattern recognition.

One of the most important products of the majority of tools, processes and, phenomena in mining engineering and earth sciences are high-frequency elastic waves, often referred to as acoustic waves. These acoustic waves can be a useful tool for prediction and measurement, monitoring and diagnosis. Due to the importance of engineering activities that should be specific, measurable, available, reliable and time-based (SMART), Acoustic Emission (AE) techniques can be integrated into engineering operations such as excavation to give exact estimations or simplify some aspects of investigations. Hence, these techniques are expected to play an increasing role in the detection, monitoring, and measurement in engineering applications. With the development of acoustic signal processing methods in earth sciences and the growing need for accurate, fast, and cost-effective prediction, monitoring and measurement methods, AE tools and techniques are expected to turn into powerful alternatives to current methods. The purpose of this paper is to review the application of the acoustic methods as a tool in various projects. For this purpose, the application of AE methods has been reviewed in different fields related to earth sciences including mining engineering, drilling engineering, geology, petroleum engineering, and other related fields. According to the purpose of using these methods, the application of AE is divided into three groups: prediction and estimation, monitoring and performance assessment, and detection. The use of AE methods, among other laboratory or in-situ methods, is very fast and accurate, and by only installing specific sensors with data logging equipment, it has been able to process and analyse data online and remotely. Finally, the possibility of using AE techniques in design and calculating in various projects and as a tool for decision making was evaluated.

“…There are a large number of methods to measure the strength of rocks, such as nondestructive acoustic emission technology [6][7][8] at the microscopic scale and true triaxial systems [9] and dynamic loading systems [10] at the macroscopic scale. In this experiment, the dynamic mechanical properties of rock are studied by the split Hopkinson pressure bar (SHPB) system.…”

Investigations on rock dynamics have been comprehensively focused on when the dynamic impact is perpendicular to the trend of the flaws, while understanding the dynamic mechanical properties and failure characteristics of rock with pre-flaws parallel to the loading direction remains unrevealed. In this study, impact tests are performed to experimentally study the dynamic mechanical properties, failure characteristics, and energy evolution of pre-flawed sandstone using the split Hopkinson pressure bar (SHPB) apparatus, in which the pre-flaws are parallel to the loading direction. The results show that for specimens, the dynamic loading rate and the number of flaws greatly influence the dynamic strength, peak strain, energy absorption rate, and failure behaviors. The dynamic strength increases exponentially with an increase in loading rate and decreases with an increase in flaw numbers. The fractal dimension of triple-flawed specimens is the largest at the same loading rate range. The failure modes of different pre-flawed specimens show a transition from tensile failure to tensile-shear failure with the increase of dynamic loading rate.

“…Then, in order to measure and efficiently estimate the mechanical properties of rock materials under various conditions, many scholars used acoustic waves in real-time and non-destructive detection and monitoring applications to study the mechanical strength and macro-and microstructural characteristics of rock [21]. In Materials 2023, 16, 3041 2 of 17 addition, acoustic frequency analysis methods are also applied to study rock characteristics, and the results show that there is a reliable mathematical relationship between the two factors [22]. Until now, multitudinous scholars have conducted effective research in this field.…”

Considering that a jointed rock mass in a cold area is often affected by periodic freeze–thaw cycles and shear failure, definitions for the mesoscopic and macroscopic damage to a jointed rock mass under the coupling of freeze–thaw and shear are proposed, and the damage mechanism is verified according to experimental results. The results show that: (1) the jointed rock specimens increase macro-joints and meso-defects, the mechanical properties deteriorate significantly under freeze–thaw cycles, and the damage degree becomes more and more significant with the increases in freeze–thaw cycles and joint persistency. (2) When the number of freeze–thaw cycles is constant, the total damage variable value gradually increases with the increase in joint persistency. The damage variable difference in specimens with different persistency is distinct, which is gradually reduced in the later cycles, indicating a weakening influence of persistency on the total damage variable. (3) The shear resistance of non-persistent jointed rock mass in a cold area is determined by the coupling effect of meso-damage and frost heaving macro-damage. The coupling damage variable can accurately describe the damage variation law of jointed rock mass under freeze–thaw cycles and shear load.
