关键词：Unveiling spatial heterogeneity in urban underground space development patterns and mechanisms for differentiated planning A points of interestbased study Shanghai
摘要：Highlights Spatial heterogeneity of urban underground space (UUS) development in Shanghai was investigated with a high spatial resolution. UUS spatial patterns were quantitatively analyzed by points of interest. UUS development mechanisms diverged significantly in the main city and the suburbs. Differential planning policies were advocated to improve UUS utilization efficiency.

关键词：Seismic analysis and design of tunnels within fault ground A review
摘要：Highlights The main cases of seismic damage to tunnels within fault ground historically are reviewed. Research methods, including field investigations, analytical solutions, physical experiments, and numerical simulations, are discussed. The application of self-designed equipment for tunnel mechanical response under fault dislocation is emphasized. Seismic design and countermeasures for tunnels across faults are analyzed. Future research topics to be investigated for tunnels within fault ground, especially under earthquake forces, are proposed.

关键词：Dynamic cracking properties and generating conditions of coal under rapid gas release
摘要：Highlights The dynamic cracking properties of coal during the rapid gas release (RGR) process were obtained by gas release tests. The critical thresholds of coal cracking and damage during the RGR process were obtained. A new criterion model suitable for coal damage caused by the RGR was constructed, which provides theoretical support for outburst risk prediction from the perspective of fracture mechanics.

关键词：Mechanism and disaster control new technology of strong ground pressure manifestation in ultralarge mining face
摘要：Highlights A new mechanical model for the lateral support system of the mining site has been established, supplementing the traditional S-R rock fracture movement theory. Revealed the mechanism of strong mining pressure manifestation in the double-key strata mining field of extra-thick coal seams. A mining pressure control method has been proposed to effectively protect a large deformation roadway.
