Vibration Behavior during Underground Drilling Based on an Innovative Measurement Method and the Application

Pressure relief drilling is one of the most common techniques to reduce impact rock burst, but useful dynamic phenomena in process are ignored due lack corresponding technical methods. Based on fact, an innovative measurement method for vibration signals during construction by pneumatic drill rig presented this study. The acquisition and analysis show that information can reflect depth, amplitude different depth pressure, events depths pressure effect. proposed study great significance supervision work quantity, disclosure situation, evaluation
