Summary: To address the parametric design problem of blasting with water-coupled medium and improve rock breaking quality, this study quantified and examined blasthole pressure and explosive crack growth length in the scenario of water-coupled blasting. The results showed that in this scenario, both blasthole pressure and crack length decrease as the decoupled coefficient eta increases, with blasthole pressure being more significantly influenced by eta.

Summary: In this study, the influence of key blasthole parameters on tunnel overbreak during blasting construction was determined using an independently developed intelligent detection system. The results showed that blasthole angle, opening position, and charge mass have significant effects on tunnel overbreak, with blasthole opening position being the key parameter. The theoretical analysis, finite element simulation, and measurements yielded consistent distributions of tunnel overbreak volume.

Summary: This study proposes an incremental extreme extraction method to investigate the distribution and characteristics of ground vibration from deep-hole blasting in open-pit mines. The method effectively improves the utilization rate of data by extracting and screening extreme values of blasting vibration signals. The analysis of particle velocity vector reveals that the vertical direction has a significant advantage over the other two directions, and the angle between the extreme particle velocity vector direction and the ground plane is primarily distributed in the range of 60 to 90 degrees.

Summary: The study established an optimal predictive PPV model using a generalized feedforward neural network structure and a novel automated intelligent parameter setting approach. Two new optimized hybrid models were developed, incorporating GFFN with firefly and imperialist competitive metaheuristic algorithms (FMA and ICA). Results showed that the predictability level of the hybrid GFFN-FMA model significantly outperformed the GFFN-ICA and optimum GFFN models.

Summary: With the widespread usage of electronic detonators in blasting engineering, it is crucial to study the frequency spectrum characteristics under precise delay time for blasting design and safety assessment. This paper calculates the frequency spectra induced by blasting vibration under different delay times and distances, investigates the frequency distribution and energy characteristics of various frequency bands, and conducts numerical simulation and electronic detonator blasting experiments to demonstrate the findings. The results show that the delay time and distance have an impact on the frequency and energy distribution of blasting vibration, and a recommended delay time of 7-12 ms is suggested to protect structures in the blasting area.

Summary: The charge structure in the cutting area has significant engineering significance in tunneling practices with soft and broken surrounding rocks. The investigation of the effect of charge structure on blasting performance showed that using an air deck at the blasthole bottom effectively weakened damage and reduced cleaning time for loose rocks. Numerical and field experimental results were consistent in demonstrating the advantages of using an air deck in roadway excavation.

Summary: The study presents a methodology for determining the behavior of vibrations generated in any rock mass based on a single blast in a trench excavation, achieving high confidence level in a simple manner. The proposed approach can have an important impact in reducing potential consequences of vibrations for surrounding construction and achieving the required definition of rock mass, particularly useful for reducing cost and time in projects where blasting techniques are applied.

Summary: This paper investigates and controls blasting-induced ground vibration under cold conditions. Experimental and numerical simulation results show that the wave velocity of frozen rock mass is faster, the vibration propagation speed is slower, and attenuation coefficient decreases with increasing freezing depth, leading to stronger dynamic responses in structures under frozen conditions.

Summary: Blasting is still considered an important alternative for conventional excavations, but the ground vibration it generates can be harmful to nearby structures and should be prevented. A novel Jaya-XGBoost model was developed to predict blast-induced peak particle velocity (PPV) with high reliability using 150 sets of data and the Jaya algorithm for optimization. This model outperformed other machine learning models and traditional empirical models in predicting ground vibration.

Summary: This article points out the problems with current vibration testing methods used for road transport packaging systems, mainly lack of representativeness, failure to consider all vibration scenarios, and excessive reliance on limited data. It is suggested that future improvements to testing methods require comprehensive collection of a broader range of evidence and the use of correct scientific analysis.

Summary: It has been suggested that using liquefied natural gas as a fuel source for heavy goods vehicles could lead to reduced greenhouse gas emissions. However, there has been little comparative analysis across various studies. This review provides a comprehensive examination of the well-to-wheel lifecycle emissions of liquefied natural gas for heavy goods vehicles in comparison to diesel. The primary factors affecting the emissions are the fuel efficiency of natural gas engines relative to diesel and methane leakage across the supply chain.
