Mathematical Modeling and Numerical Simulation in Rock Mechanics and Mining Engineering

Topic Information

Dear Colleagues,

In recent decades, the design and construction of geotechnical engineering such as mines, tunnels, hydropower stations, and nuclear waste repositories have been surging in scale, and this trend is expected to continue in the future. These large-scale engineering projects are closely related to rock mechanics and mining engineering. As rock engineering goes increasingly deeper for exploitations, the rock masses are susceptible to the effects of high temperatures and high in situ stresses. The complex engineering environment often leads to the instability of engineering rock mass. Hence, it is necessary to use various means to study the behavior of rock mass under THM coupling and optimize the design for safe and efficient mining practices. Mathematical modeling and numerical simulation have become indispensable tools in this field, enabling engineers and scientists to better understand and predict the behavior of rock masses and design effective mining strategies.

This Topic on "Mathematical Modeling and Numerical Simulation in Rock Mechanics and Mining Engineering" aims to provide a platform for researchers to present their latest advances in this rapidly evolving field. The issue will cover a wide range of topics, including but not limited to constitutive modeling of rock materials, numerical methods for rock mechanics (FEM, XFEM, SPH, DDA, DEM, FDEM and NMM, etc.), rock fracture mechanics, numerical simulation of mining processes, geotechnical monitoring and control, and optimization of mining practices. This issue can serve as the missing link between numerical models and engineering practices. Therefore, "Mathematical Modeling and Numerical Simulation in Rock Mechanics and Mining Engineering” is dedicated to and welcomes all relevant scientific research in order to deepen the understanding of mathematical modeling and numerical simulation in rock masses. Authors are invited to submit their relevant research contributions to this Topic.

The mining of shallow coal seams with hard roofs poses a threat to surface structures. In order to ensure the protection of these buildings, backfill mining is increasingly used in these types of coal seams. However, due to the lack of appropriate surface subsidence prediction methods, there are concerns about whether backfill mining can meet the requirements of building protection. In this study, through numerical simulation and physical experiments, the movement characteristics of the strata and surface were studied in the backfill mining of a shallow coal seam with a hard roof. Our results indicate that the backfilling ratio significantly influences strata movement and surface subsidence. As the backfilling ratio increases, the surface deformation in the backfill under the hard roof of the shallow coal seam transitions from discontinuous to continuous. When the backfilling ratio exceeds 60%, the deformation characteristics of the overburden and surface align with the probability integral method model. Consequently, a novel surface subsidence prediction method for backfill mining in shallow coal seams under hard roofs is proposed. This method was successfully applied at Yungang Mine, validating its effectiveness. These research findings have significant practical implications for the design of backfill mining in shallow coal seams under hard roofs. Full article
