In a groundbreaking study published in ‘工程科学学报’ (Journal of Engineering Science), researchers have unveiled a comprehensive analysis of the dynamic–static relationship in rock blasting, a field critical to construction and mining industries. Led by Renshu Yang from the School of Civil and Resource Engineering at the University of Science and Technology Beijing, this research aims to refine how explosives are used for rock fragmentation, a process that has traditionally relied on empirical methods and field tests.
The study highlights the dual nature of the forces at play during blasting: the high-energy, short-duration stress waves generated by explosives, referred to as “dynamic action,” and the lower-energy, longer-lasting effects of blasting gases, termed “quasi-static action.” Understanding the interplay between these two forces is essential for improving the efficiency and safety of blasting operations. Yang emphasizes, “The coupling mechanism between explosive energy release and rock fragmentation is a pivotal area of research that could transform blasting practices.”
Historically, the blasting process has been fraught with challenges, including inefficiency, high costs, and safety risks. Traditional designs often focus solely on the end result—rock fragmentation—while neglecting the nuances of the blasting process itself. Yang’s research introduces a paradigm shift by investigating the dynamic–static relationship, which could lead to more controlled and effective blasting techniques. The study categorizes the evolution of research into three stages, with the latest stage (2016-present) emphasizing the role of blasting gas in the fragmentation process.
As the construction sector increasingly seeks to optimize operations and minimize environmental impacts, the implications of this research are significant. By employing advanced numerical simulations alongside experimental methods, Yang and his team have shed light on how blasting gases influence energy transfer and crack propagation. This could lead to more precise blasting strategies, ultimately saving time and resources while enhancing safety protocols.
“By understanding the behavioral characteristics of blasting gas under different conditions, we can provide theoretical support for practical engineering applications,” Yang notes. This insight not only enhances the safety and efficiency of blasting operations but also aligns with broader industry trends toward sustainable and responsible construction practices.
As the construction industry grapples with the complexities of modern projects, the findings from Yang’s research could pave the way for innovative blasting techniques that prioritize both effectiveness and safety. The study underscores a shift from experience-based practices to data-driven approaches, promising a future where blasting engineering is guided by rigorous theoretical frameworks.
