Horizontal jet-mechanical combined rock breaking test device and method

A horizontal jet-mechanical combined rock breaking test device, comprising:

• a reaction frame, wherein on the reaction frame is provided a multi-mode cutter head, plural jet-mechanical combined cutters are provided on the multi-mode cutter head, and on one end of the reaction frame is provided with a surrounding rock stress simulation bin for loading a rock sample;
• and
• the multi-mode cutter head is connected to a driving mechanism, and the multi-mode cutter head is configured to advance and rotate horizontally along the reaction frame under the action of the driving mechanism, so that the jet-mechanical combined cutters are capable of acting on the rock sample;
• the multi-mode cutter head comprises a cutter head base, a high-pressure rotary joint, a diverter, the jet-mechanical combined cutter and a pipeline, wherein the jet-mechanical combined cutters are provided on one side of the cutter head base, the high-pressure rotary joint is provided on the other side of the cutter head base, the high-pressure rotary joint is connected to the diverter, and the diverter is connected to a jet nozzle in each jet-mechanical combined cutter through the pipeline;
• the plural jet-mechanical combined cutters comprise a measuring component, the measuring component comprises a ranging sensor, and the ranging sensor is provided on a cutter rest to monitor a distance between a hob of the jet-mechanical combined cutter and a target object;
• and
• each of the jet-mechanical combined cutters comprises a cutter holder, a mechanical cutter module and a jet cutter module are detachably provided on the cutter holder, and relative positions of the jet cutter module and the mechanical cutter module are adjustable.
