Research on Precise Identification of Rock Strength Based on Bolt Drilling Parameters
Energy Science &Engineering, EarlyView.Drilling detection test platform. ABSTRACT During roadway excavation, the presence of weak interlayers and fractured rock masses significantly affects roof stability. To achieve timely and effective roadway support, it is crucial to identify and predict different rock types based on drilling signals from roof bolters.
