Field investigation of grout propagation within a caving mass under flowing water conditions in a metal mine

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigated the characteristics of two‐liquid slurry propagation filling of underground concealed spaces under flowing water conditions in metal mines using on‐site engineering tests. We proposed four different grout stratigraphic classifications, investigated four main factors affecting grout propagation, and summarized five different ...

Study on the failure mechanism of the shield excavation face in the sandy cobble stratum under different buried depths

open access: yesDeep Underground Science and Engineering, EarlyView.
Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...
