Seismic Advance Detection During Roadway Excavation in Underground Coal Mines: Method and Field Applications

Chuanjiu Zhang, Sushe Chen, Donglin Fan, Fengjuan Tao et autres

Safe and efficient roadway excavation is critical to intelligent coal mine development, while advance geological detection remains challenging under continuous excavation conditions. This study proposes a seismic advance detection method conducted concurrently with excavation, utilizing vibrations generated by roadheaders as seismic sources …

Field Evidence of Frequency-dependent Apparent Body-wave Velocity Transition

Qiyu Wu, M. Peng, Liu Liu, Zhen Ming Shi et autres

Frequency-dependent fluctuations of body-wave traveltimes in heterogeneous media have been extensively documented at global and laboratory scales, yet they have never been systematically observed in geophysical prospecting. The difficulty faced by prospecting stems from a fundamental acquisition challenge: the inherent trade-off between …

Single Borehole Detection of Geological Anomalies in Coal Mine Using Impulse Radar

Fengjuan Tao

Geological anomalies, including faults, fractured zones, and collapse pillars, pose serious threats to mining safety by increasing the risk of water inrush and roof collapse. To enable accurate ahead-of-face detection, this paper presents the development and practical application of a single-borehole impulse …

Long-term horizontal displacement induced by shield tunneling in consolidating soft ground

Haibo Wang, Rongjun Zhang, Fengjuan Tao, Junjie Zheng

• Investigate how consolidating state affects shield tunneling-induced horizontal displacement. • Simulate the magnitude and distribution of long-term horizontal displacement numerically. • Compare the differences in long-term horizontal displacement between normally-consolidated and consolidating cases. • Propose an empirical method to estimate long-term …

Estimation of deformation behaviour of deep excavation in under-consolidated soft ground

Fengjuan Tao, Rongjun Zhang, Haibo Wang, Junjie Zheng et autres

The under-consolidated (UC) state affects the deformation behaviour of deep excavation in soft soil and poses potential risk to the safety of adjacent facilities. However, deformation models for deep excavation in UC ground have not been well investigated. This paper presents a …

Degradation mechanisms of soil arching under a localized cyclic surface loading

Fengjuan Tao, Guanbao Ye, Zhen Zhang, Jie Han et autres

Soil arching causes stress redistribution in many earth structures, such as pile-supported embankments and buried structures. A localized cyclic surface load (e.g., footing and traffic load) would weaken the arching effect and cause structural safety at potential risk. This paper presents a …

Advances in Neoadjuvant Immunotherapy for Locally Advanced Esophageal Cancer

Xue Ji, Lixia Tian, Fengjuan Tao, Tian Xue et autres

Abstract: Esophageal cancer is one of the common malignant tumors in China with a high mortality rate. Neoadjuvant chemoradiotherapy (nRCT) is currently the primary treatment method for locally advanced esophageal cancer. However, nRCT has not been not widely applied in China due …
