Abstract
By analyzing the control of surrounding rock passing through faults in the excavation face,this paper explored the application of methods and technologies for controlling surrounding rock passing through faults in mining operations.Firstly,it introduced the significance and importance of controlling the surrounding rock when passing through faults,then outlined the current research status and progress in China,and pointed out the existing problems and challenges.Next,it analyzed the technical methods for controlling the surrounding rock of the excavation face through faults,including stability assessment and prediction methods,support and reinforcement methods,geological exploration,and rock layer control techniques.Finally,it pointed out the issues that need to be paid attention to in controlling the fault crossing of the excavation face,such as the relationship between fault type and surrounding rock properties,groundwater leakage and discharge,etc.It is of great significance to guide the control of fault surrounding rock in mining operations.
