Study on spatiotemporal evolution law of surrounding rock stress in deep high-stress soft rock roadways

To address large deformation and support failure in deep, high-stress soft-rock roadways, this study investigates the − 810 m track main roadway of Pansan Coal Mine using fiber Bragg grating three-dimensional stress monitoring and borehole fracture observation, combined with FLAC3D numerical simulations. Results show t...

Scientific basis of geomechanical monitoring and support design in deep gold mining

Deep-level underground gold mining is characterized by complex geomechanical conditions, particularly within tectonically disturbed zones where stress redistribution and rock mass heterogeneity significantly affect excavation stability. This study aims to develop scientific foundations for ground support design based o...

Precise three-dimensional borehole pressure relief technology for surrounding rock control of large deformation roadways in high-stress coal seams.

To address the large deformation control problem of surrounding rock in high-stress roadways subjected to multiple disturbances, the 112 transport crosscut of Laoyingshan Coal Mine in Guizhou Province was taken as the engineering background. The deformation and failure mechanism of surrounding rock in disturbed high-st...
