Research on the evolution patterns of plastic zones in rock masses of multi-disturbance roadways and support control measures
Qiang Yao
The dynamic response characteristics of stress redistribution in roadway surrounding rock and the distribution patterns of plastic zones during different stages are pivotal to controlling rock mass stability. Addressing the vulnerability of retained roadways to repeated mining impacts from adjacent working faces under dual- or multi-roadway layouts, this study examines the 22,104 auxiliary transport roadway at Shangwan Coal Mine. Employing a combined approach of field investigations, theoretical
