Study on Deformation Failure Mechanism and Control Technology of Surrounding Rock in Soft Rock Roadway

Geotechnical and Geological Engineering, 2021
In order to reveal the mechanism of surrounding rock deformation and instability of soft rock roadway in 12# working face of Puhe coal mine, and synthetical analysis of the surrounding rock, deformation and failure of the roadway shows that the original support scheme is difficult to maintain the stability of roadway.

Development of fractures in soft rock surrounding a roadway and their control

Mining Science and Technology (China), 2011
Abstract As the excavation of roadway, new fractures will be formed and the pre-existing fractures extend with the redistribution of stress in surrounding rocks. Eventually, fracture zone and bed separation are formed in rocks because of the developed fractures.
