Development of a power recovery-based dynamic loading system for full-size drill rods in coal mines
ObjectiveThis study aims to simulate the actual forces applied to drill rods during the borehole drilling for gas drainage from underground coal mines to satisfy the requirements of drill rods’ fatigue tests. MethodsThis study designed a dynamic loading system for full-size drill rods in coal mines....
