**Preface to "Mining Safety and Sustainability II"**

The mining industry provides important support for development of the global economy and society. With further economic development and the continuous improvement in people's living standards, the demand for mineral resources is gradually increasing. However, with the increasing depth of mining, the difficulty of mining also increases, thus placing higher requirements for mining equipment and safety. Detection of the mineral exploration environment, improving the safety of mining operations, developing intelligent tunneling equipment, and ensuring the coordination of human–machine–environment in the mining production system have become necessary conditions for promoting the transformation of mining methods and achieving the goal of "double carbon". Exploring safe, efficient, and sustainable methods for mining mineral resources has become urgent. In the past, scholars around the world have carried out extensive research work on safe and sustainable mining, but because mining operations are resource-consuming and characterized by productive behaviors, applying the principles of safety and sustainability to mining itself is challenging.

It is important to reduce the risk of mining accidents and disasters, enhance the safety of mining operations, and improve the efficiency and sustainability of mineral resources development. Therefore, it is necessary to extract useful knowledge from the process of mineral resources development and resource integration by means of experimental techniques, simulation methods, data mining, theoretical innovation, technological development, and other methods. This will provide further theoretical and technical support for guiding the normative, green, safe, and sustainable development of the mining industry. This Reprint aims to present new research and recent advances in the safety and sustainability of mining.

Last but not least, thanks to all authors for their excellent and meaningful contributions to this topic. We welcome more experts and scholars to present your new ideas regarding safety mining, sustainable mining, mineral resource management, technology of intelligent mining, research and development of intelligent mining equipment, sustainable development, new mining methods, and related topics.
