Abstract

Carbon capture, utilization, and storage is a crucial technological approach to mitigating global warming. As a promising geological storage technology, CO2 storage in coal mine goafs not only addresses the challenge of source-sink mismatch but also facilitates the resource utilization of abandoned coal mine goafs and shafts worldwide. However, ensuring the long-term sealing and integrity of the caprock and preventing CO2 leakage remain the core challenges for this technology. This paper systematically summarizes and analyzes CO2 storage in coal mine goafs from the perspectives of storage mechanisms, capacity evaluation, monitoring and early-warning systems, and multi-field coupling effects. The study reveals that establishing a real-time, systematic, and intelligent lifecycle safety assurance system is the key to overcoming the core challenges of CO2 storage in coal mine goafs and achieving long-term safe and stable operation. This paper aims to provide a scientific basis for the development and application of CO2 storage technology in coal mine goafs.
