Abstract: In deep coal mining, skip mining techniques are increasingly adopted, yet their discontinuous extraction sequences and unique coal pillar support mechanisms create complex overburden failure patterns. This complexity gives rise to severe multi-source water hazards, including persistent threats from bed-separation water, goaf water accumulation, and structural water ingress. The intricate hydro-geological conditions, characterized by variable... More

Abstract: With the increasing scale of underground space construction, urban karst geological disasters in China are becoming more and more serious, having a serious impact on people’s daily lives and engineering construction. In this paper, a variety of monitoring methods are used to analyze the spatial and temporal variation characteristics of regional land subsidence during the... More
