Researches focusing on shock and vibration in the deep mining environment have rapidly increased in recent years because of the exhaustion of shallow mineral resources and the dramatic increase of destructive hazards induced by intensive deep mining. These challenging issues require researchers to investigate the generation, characteristics, and mechanisms of shock and vibration in deep mining from multiple aspects through different research techniques, as well as to explore feasible solutions to establish a solid foundation for safe and efficient deep mining.

This special issue collects two review articles, where one comprehensively summarizes the damage and failure mechanism of rock under combined multiple strain rates as well as its numerical simulation and another reviews some developments for microseismic/acoustic emission (AE) source localization. Besides, this special issue also collects thirty-one original research contributions that present recent advances about shock and vibration in deep mining science by applying theoretical analysis, numerical simulation, laboratory experiments, field tests, and some coupled research techniques. The collection of papers with different research interests evidently points to the need for communication among these researches. It is hopeful that this special issue will help the dialog to fruition and access insights into directions for future research.

W. Zhu et al. in the review article entitled “Numerical Simulation on Damage and Failure Mechanism of Rock under Combined Multiple Strain Rates” reviewed the state of the art of rock damage and failure under different strain rates, summarized the corresponding numerical models, and presented some numerical examples to provide insights into the rock failure mechanism. The review article by L. Dong et al. entitled “Some Developments and New Insights for Microseismic/Acoustic Emission Source Localization” presented the MS/AE source localization methods used in the dynamic mining environment, and some novel perspectives were proposed for improving location accuracy considering different engineering backgrounds.

The theoretical analysis is mainly applied in six papers, where four papers proposed new methods for effectively analyzing mine seismicity and two papers focused on the damage mechanisms of rock/coal mass. The paper entitled “A Nonparametric Method for Automatic Denoising of Microseismic Data” by P. Peng and L. Wang proposed a nonparametric automatic denoising method for microseismic data that consists of three major steps. Z. Zhou et al. in the paper entitled “Discrimination of Rock Fracture and Blast Events Based on Signal Complexity and Machine Learning” developed a new method for discriminating rock fracture and blast events by combining signal complexity and machine learning.

Zhang et al. entitled “Focus Energy Determination of Mining Microseisms Using Residual Seismic Wave Attenuation in Deep Coal Mining” presented a method to determine the microseismic focus energy based on the energy attenuation characteristics of residual waves in deep rock. The paper by B. Li et al. entitled “Discriminant Model of Coal Mining Microseismic and Blasting Signals Based on Waveform Characteristics” established a discriminant model for coal mining MS and blasting signals by using the Fisher linear discriminant method. Combined with synthetic datasets and filed datasets, the methods proposed by the above four papers showed good performances regarding their research issues. In addition, Y. Wang et al. in the paper entitled “Blast Induced Crack Propagation and Damage Accumulation in Rock Mass Containing Initial Damage” researched the effect of small blasthole diameter blast on crack propagation and damage accumulation in water-bearing rock mass containing initial damage.

Four papers mainly applied the numerical simulation to reveal the fracture propagation and mechanics responses during the mining process. The paper entitled “Adaptive Finite Element-Discrete Element Analysis for Microseismic Modelling of Hydraulic Fracture Propagation of Perforation in Horizontal Well considering Pre-Existing Fractures” by Y. Wang et al. utilized the adaptive finite element-discrete element method to identify the fracture propagation and investigate microseismic modelling. D. Bing et al. in the paper entitled “A Numerical Research on Crack Process of Gypsum Containing Single Flaw with Different Angle and Length in Uniaxial Loading” investigated the crack behavior of rock or rock-like materials in uniaxial loading. Additionally, the responses of the roadheader’s body during the horizontal cutting process are analyzed in the paper by K. Zong et al. entitled “Multifactor Analysis of Roadheader’s Body Pose Responses during the Horizontal Cutting Process.” Similarly, the paper by M. Zhang et al. analyzed the vibration of the roadheader rotary table through the finite-element numerical simulation method.

The laboratory experiment is an effective method for exploring the behavior of rock mass and its characteristics under different engineering backgrounds. This special issue collects sixteen original contributions that take the laboratory experiment as a main research technique. To be specific, Z. Wu et al. in the paper “Experimental Study on the Stress Sensitivity and Influence Factors of Shale under Varying Stress” investigated the relationships between the shale porosity and permeability and the effective stress, as well as analyzed the stress sensitivity of shale.

We believe that this special issue will be useful for researchers and practitioners working in the broad rock engineering and underground engineering.
