Switching mechanism and optimisation research on a pressure-attitude adaptive adjusting coal seam water jet slotter

To investigate the attitude-switching mechanisms of existing jet slotters, which integrate drilling, punching and slotting operations, and to improve its fracture ability, we used the power bond diagram theory to analyse the dynamic flow pressure, and force of slotters.A mathematical model was developed for the dynamic characteristics of slotter sy
