Modulation of annular fluid enhanced self-excited pulsed water jet and its coal breaking characteristics

There are some bottleneck problems in the pressure relief and antireflection technology of submerged water jet in a downward hole, such as weak impact force, low coal breaking efficiency, less coal cutting and poor adaptability. In this study, the idea and principle of coal breaking and antireflecti...
