This Research Topic is Volume II of a series. The previous volume can be found here: Advanced Materials and Technologies for Sustainable Development of Underground Resources. The sustainable development of underground mineral resources faces great challenges. On the one hand, as mining continues to develop deeper into the earth, high pressure, high temperature, high water pressure, strong disturbance and complex geological conditions are increasingly aggravating the deformation of surrounding rock in underground engineering structures and even inducing disasters. On the other hand, mining wastes such as coal gangue and tailings pollute water, air and land. Materials and technologies to solve these problems are in urgent need of revolution and optimization. Breakthroughs in theory, method, and applicability are needed to achieve the safe, green and efficient mining of underground resources in harsher environments and more complex conditions.
Constructing stable underground spaces and mining safely through advanced materials and technologies is our primary goal. In this process, the environmental damage caused by mining and waste should also be addressed to achieve the sustainable goal. For example, using alkali activation, nano-modification or other advanced technologies to enhance cemented backfill materials while reducing costs to reply to the great challenge of mining waste management. Developing high-performance grouting materials and methods to solve the corresponding engineering problems in harsh conditions of high-pressure groundwater, high temperature and strong disturbance. In addition, the sustainable goals achieved by functional materials for energy storage, self-healing and carbon capture are also very important. The matching between these materials, technologies and deep earth rocks is also very important, which involves multiple information monitoring and stability assessment.
We encourage new discoveries in rock mechanics and geotechnical engineering. We also encourage the use of advanced materials and technologies to solve current deep engineering problems. Theoretical and simulation work closely related to material, technology and engineering is also encouraged. The multidisciplinary intersection of geotechnic, material and environment is advocated by this topic. We welcome papers covering the following areas including Mechanical properties of rocks and materials, Cemented waste rock backfill, Mining waste leaching and solidification evaluation, Cement-based grouting material characterization, Material functionalization applications, Long-term stability of underground structure, Multi-source information monitoring, Strata movement control, Seepage and water disaster prevention.
